Therefore, when observing the vicinity of own ship, use the smaller observation range. 2 When decreasing the observation range, press the [RANGE-] key. Decreasing the observation range will enable the vicinity of own ship to be enlarged. However, caution must be taken because video images of the area beyond the observation range cannot be displayed.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-100.png)
![3-6 3.2 Observe and Adjust Video yy y3 3.2.3 Tune CAUTION Normally, use the automatic tune mode. Use the manual tune mode only when best tuning is not possible in the automatic tune mode due to deterioration of magnetron. This radar system provides the automatic tune mode and the manual tune mode. The automatic tune mode automatically adjusts the tuning of the transmitting frequency and the receiving frequency, and the manual tune mode enables tuning to be adjusted by using the dial located on the operation unit. The tune mode currently being used is displayed in the tune mode switching (lower left of the display ⑫ on page 2-18). When using the automatic tune mode Procedures 1 Put the cursor on the tune mode switching (lower left of the display ⑫ on page 2-18) and press the [ENT] key.

![3-7 3.2.4 Adjust Gain [GAIN / PL] CAUTION If the gain is too high, unnecessary signals including receiver noise and false video increase resulting in reduction of visibility of targets. On the contrary, if the gain is too low, targets including ships and dangerous objects may not be clearly indicated. Procedures 1 Adjust noise of the display by turning the [GAIN / PL] dial until targets can be easily observed. Turning [GAIN / PL] dial clockwise increases gain. Turning [GAIN / PL] dial counterclockwise decreases gain. By increasing receiving gain, the range to observe radar video is widened. To observe densely crowded targets or short-range targets, reducing the receiving gain will enable the targets to be easily observed. 3.2.5 Suppress Sea Clutter [AUTO-SEA] CAUTION When using the sea clutter suppression function, never set the suppression level too high canceling out all image noises from the sea surface at close range. Detection of not only echoes from waves but also targets such as other ships or dangerous objects will become inhibited. When using the sea clutter suppression function, make sure to choose the most appropriate image noise suppression level.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-102.png)

Turning [AUTO-SEA] dial clockwise suppresses sea clutter returns. Turning [AUTO-SEA] dial counterclockwise intensifies sea clutter returns. The sea clutter suppression function suppresses sea clutter returns by decreasing the receiving gain on a short range. Turning the [AUTO-SEA] dial clockwise heightens the effect of sea clutter suppression. However, be careful that excessive suppression causes low signal-strength targets such as buoys and boats to disappear from the radar display. Using the automatic sea clutter suppression mode The sea clutter suppression in accordance with the intensity of sea clutter is possible. Use this mode when the sea clutter's intensity differs according to directional orientation. Procedures 1 Press the [AUTO-SEA] dial.

![3-9 3.2.6 Suppress Rain / Snow Clutter [AUTO-RAIN] CAUTION When using the rain / snow clutter suppression function, never set the suppression level too high canceling out all image noises from the rain or snow at the close range. Detection of not only echoes from the rain or snow but also targets such as other ships or dangerous objects will become inhibited. When using the rain / snow clutter suppression function, make sure to choose the most appropriate image noise suppression level. Using the manual rain / snow clutter suppression mode Procedures 1 Adjust the rain / snow clutter returns of the display by turning the [AUTO-RAIN] dial until targets can be easily observed. Turning [AUTO-RAIN] dial clockwise suppresses rain / snow clutter returns. Turning [AUTO-RAIN] dial counterclockwise intensifies rain / snow clutter returns. When the [AUTO-RAIN] dial is turned clockwise, the rain / snow clutter suppression function suppresses rain / snow clutter returns and gets targets hidden by rain / snow clutter returns to appear of the display. However, be careful that excessive suppression may cause small targets to be overlooked. Since the rain / snow clutter suppression function also has the effect of suppressing sea clutter, the suppression efficiency improves when the [AUTO-RAIN] dial is used with the [AUTO-SEA] dial. In general, turn the [AUTO-RAIN] dial fully to the left.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-104.png)

![3-94 3.9 Use Function Key yy y3 3.9 USE FUNCTION KEY [FUNC] “Radar Function Setting” is provided for easily obtaining the best radar video by saving complex radar signal processing settings in the optimum status by use, and calling the setting in accordance with the conditions for using the function. Functions are factory-set for general use, and the settings can be fine adjusted by operating the menu. Four function modes are available, and they are factory-set as follows: Function 1 : Coast Useful for observing short-range videos. Function 2 : Deepsea This setting is suitable for general long-distance videos. Function 3 : Fishnet Useful for small target. Function 4 : Storm Useful for observing videos in stormy weather. 3.9.1 Operation Procedures [FUNC] Calling a Function Procedures 1 Press the [FUNC] key. Each time the [FUNC] key is pressed, the selection changes cyclically as follows. Function Off → Function 1 → Function 2 → Function 3 → Function 4 → Function Off The name of the current function mode is displayed in the function (FUNC) mode switching ( lower left of the display ⑤ on page 2-18). Alternatively, put the cursor on the function (FUNC) mode switching, and press the [ENT] key to conduct the same operation as the above. Changing Function Setting (temporary change) • When radar signal processing setting is changed by using the menu or button of the display while function 1 to 4 is called, the change is temporarily reflected to the operating state. • Since this method does not change the memory contents, the new setting is discarded as soon as another function is called. • When the previous function is called again, operation is performed according to the memory contents. Changing Function Setting (memory contents change) • To change the memory contents of functions 1 to 4, use the function setting menu. • For how to operate the function setting menu, see Section 3.9.3.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-189.png)

Procedures 1 Press the [FUNC] key for 2 seconds. The User Function Setting menu will appear. Specify the number for the function for which the settings are to be changed. The following are the operation overviews of each function setting item. [Page 1] [1] Mode • Selects the function name to be indicated at the lower left of the display when the function is selected. • When the setting is changed back to the factory setting, the initial value of the selected mode is called. • The following 11 modes are provided. Coast : Use this mode to monitor a relatively short range, for example, bays and coasts where many boats and ships are running. (Importance is attached to resolution.) Deepsea : Use this mode to monitor a relatively long range. (Importance is attached to long-range gain.) Fishnet : Use this mode to detect small targets hidden by sea clutter returns. (Importance is attached to sea clutter suppression, and gain to moving targets lowers.) Storm : Use this mode when many rain / snow clutter returns or sea clutter returns are detected in stormy weather. (Importance is attached to rain / snow clutter and sea clutter suppression, and gain slightly lowers.) Calm : Use this mode when only a few rain / snow clutter returns or sea clutter returns are detected. Rain : Use this mode when sea clutter is not strong but rain / snow clutter is strong. (Importance is attached to rain / snow clutter suppression, and gain slightly lowers.) Bird : Use this mode to detect flocks of sea birds. Long : Use this mode to monitor utmost distances in the broad ocean. Buoy : Use this mode to detect small targets like radio buoys in areas outside the sea clutter area. (This mode displays targets of which detection probability is low.) User1 : General mode used when the nine modes above are not applicable. User2 : General mode used when the nine modes above are not applicable.

[Page 1] [5] Auto STC / FTC (Auto Sea / Rain) • Detects unwanted waves such as rain / snow clutter and sea clutter and automatically suppresses them. • When the sea state or weather changes, this function automatically performs suppression processing in accordance with the situation. • Suppression processing is not full automatic, and requires the operator to adjust the afterimages of unwanted waves. • To adjust the afterimage of sea clutter, use the [SEA] dial. • To adjust the afterimage of rain / snow clutter, use the [RAIN] dial. • In areas where the density of unwanted waves is low, unwanted waves may remain being judged as targets. Thus, use the automatic clutter suppression mode together with the video process mode. • Characteristics of the automatic clutter suppression function. Off : Disables the automatic clutter suppression function. Select off when rain / snow clutter and sea clutter are not strong. AUTO Sea : Automatically detects the strength of sea clutter, and performs the most suitable sea clutter suppression processing. Even when the strength of sea clutter varies depending on the wind direction, AUTO Sea performs the most suitable suppression processing. Land like islands can be displayed naturally. Since rain clouds outside sea clutter areas are recognized as land, there is no effect of suppressing rain / snow clutter. AUTO Sea/Rain : Along with AUTO Sea, AUTO Rain automatically detects the strength of rain / snow clutter, and performs the most suitable rain / snow clutter suppression processing. When rain clouds are scattered about, AUTO Rain performs rain / snow clutter suppression processing for only the rain-cloud areas. Since land is recognized as rain clouds, land videos become obscure.

[Page 5] [1] Gain Offset • Corrects gain while the function mode is called. • Since the displayed noise level varies depending on the combination of the video process mode and the interference rejection level, gain needs fine adjustment for always obtaining the highest level. • The gain correction function saves the correction value set by the gain adjust in each function mode, so it can obtain the highest gain without the gain adjust being operated when the function mode is changed. • To set high gain, set a value on the “+” side. • To set low gain, set a value on the “-” side. • When the radar interference rejection level is increased, the noise level is lowered. Thus, set a gain correction value to the “+” side. • When the video process mode 3Scan CORREL , 4Scan CORREL , or 5Scan CORREL is used, the noise level is lowered. Thus, set a gain correction value to the “+” side. • When the video process mode Remain or Peak Hold is used, noise is hard to disappear. Thus, set a gain correction value to the “-” side. [Page 5] [2] PRF • Same function as in the Pulse Repetition Frequency described in 3.8.3.

![5-1 z There are the following limitations on use of the target acquisition and target tracking functions. [I] Resolution between adjacent targets and swapping during automatic target tracking Depending on the particular distance and echo size, resolution between adjacent targets during automatic target tracking usually ranges somewhere between 0.03 to 0.05 NM. If multiple targets approach each other, resolution will become about 0.05 NM and this may cause the system to regard them as one target and thus to swap them or lose part of them. Such swapping or less of targets may also occur if the picture of the target being tracked is affected by rain/snow clutter returns or sea clutter returns or moves very close to land. [II] Intensity of echoes and the target tracking function The intensity of echoes and the tracking function have a correlationship, and thus the target will be lost if no echoes are detected during six scans in succession. If a lost target exists, therefore, radar gain must be increased to support detection of the target. If, however, radar gain is increased too significantly, sea clutter returns or other noise may be erroneously detected and tracked as a target, and resultingly, a false alarm may be issued. [III] Adverse effects of error sources on automatic tracking To execute accurate tracking, it becomes necessary first to appropriately adjust the [GAIN], [SEA] and [RAIN] dials of the radar so that the target to be acquired and tracked id clearly displayed on the radar display. Inappropriate settings of these adjustments reduce the reliability / accuracy of automatic tracking.

![6-5 6.3 SEA CLUTTER AND RAIN AND SNOW CLUTTER In addition to the echo required for observing ships and land radar video image also includes unnecessary echo, such as reflection from waves on the sea surface and reflection from rain and snow. Reflection from the sea surface is called "sea clutter," and reflection from rain and snow is called "rain and snow clutter," and those spurious waves must be eliminated by the clutter rejection function. [I] Sea clutter Sea clutter appears as an image radiating outwardly from the center of the radar display and changing depending on the size and the shape of waves. Generally, as waves become larger, image level of the sea clutter is intensified and the clutter far away is also displayed. When waves are large and the sea clutter level is high, it is difficult to distinguish sea clutter from a small boat whose reflection intensity is weak. Accordingly, it is necessary to properly adjust the sea clutter rejection function. Table 6.2 shows the relation between the sea state (SS) showing the size of waves generated by wind and the radar's detection probability. Table 6.2 Sea state and probability of target detection S band radar (probability to detect a target at a distance of 0.4 NM) X band radar (probability to detect a target at a distance of 0.7 NM) V: Detection probability of 80 % M: Detection probability of 50 % NV: Detection probability of less than 50 % RCS SS1 to 2 SS2 to 3 SS3 to 4 SS4 to 5 0.1m2 V V-M M-NV 0.5 m2 V V V-M M-NV 1 m2 V V V V-M RCS SS1 to 2 SS2 to 3 SS3 to 4 SS4 to 5 1m2 V-M M-NV 5 m2 V V-M M-NV 10 m2 V V V V-M](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-305.png)
![6-6 6.3 Sea Clutter and Rain and Snow Clutteryyyyyy6 As shown in Table 6.3, the number of SS increases as the wind speed becomes high and the waves become large. Table 6.2 reveals that detection probability decreases from V (80 %) to NV (less than 50 %) as the number of SS increases. Therefore, even if the sea state is calm and a target clearly appears on the radar display, when the sea state becomes rough, target detection probability decreases resulting in difficulty of target detection by the radar. Table 6.3 Relation between Douglas sea state and average wind speed and significant wave height Significant wave height: an average of top N/3 higher waves when the number of waves detected within a constant time duration is N For example, in the case of a standard marine buoy, RCS of X band radar is 5 m2 as shown in Table 6.1. When observing such a target in the sea state (SS3) in which significant wave height exceeds 1.2 meters, detection probability is M-NV, as shown in Table 6.2, which indicates 50 % or less. [II] Rain and snow clutter Rain and snow clutter is a video image that appears in a location where rain or snow is falling. The image changes according to the amount of rain (or the amount of snowfall). As precipitation increases, the image of rain and snow clutter becomes intensified on the radar display, and in the case of localized heavy rain, an image similar to the image indicating land is displayed in some cases. Furthermore, because radio waves tend to attenuate due to rain and snow, the ability to detect a target in the rain and snow clutter or a target beyond the rain and snow clutter may decrease. The amount of attenuation depends on the transmission frequency, antenna beam width, and the pulse length. Figure 6.3 and Figure 6.4 show examples in which detection distance is reduced due to the influence of precipitation. Because of this, a target, which clearly appeared up to 10 NM by an X band radar (pulse width of 0.8 μs) when it was not raining, may become dimly visible up to 5 NM when the amount of rain becomes 4 millimeters per hour. Furthermore, when comparing the X band radar with the S band radar, target detection distance decreases less when an S band radar is used, which means it is influenced less by precipitation.

![6-8 6.3 Sea Clutter and Rain and Snow Clutteryyyyyy6 [III] Coping with sea clutter and rain and snow clutter When the weather is bad and the ocean is rough, the use of an S band radar is effective because the radar is not influenced by sea clutter so much and attenuation due to rain drops is small. When an X band radar is used, reducing the pulse width will reduce the influence by spurious waves, and also the spurious wave rejection function effectively works; therefore, the use of short pulse is effective when the weather is bad. By using image processing functions PROC 1 to 3, it is expected that spurious waves are further suppressed. Since optimal settings for those items can be automatically made by using the function mode, it is recommended that FUNC Storm or FUNC Rain be used by selecting the function mode when the weather is bad. For details of the function mode, see Chapter 3.9. However, these functions may make some targets invisible, particularly targets with higher speeds.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-308.png)
![6-9 6.4 FALSE ECHOES The radar observer may be embarrassed with some echoes that do not exist actually. These false echoes appear by the following causes that are well known: [I] Shadow When the radar scanner is installed near a funnel or mast, the echo of a target that exists in the direction of the funnel or mast cannot appear on the radar display because the radar beam is reflected on the funnel or mast. Whether there are some false echoes due to shadows can be checked monitoring the sea clutter returns, in which there may be a part of weak or no returns. Such shadows appear always in the same directions, which the operator should have in mind in radar operation. [II] Side Lobe Effect A broken-line circular arc may appear at the same range as the main lobe of the radar beam on the radar display. This type of false echo can easily be discriminated when a target echo appears isolated. (See Figure 6.5) HL Figure 6.5 [III] False Echo by Secondary Reflection When a target exists near own ship, two echoes from the single target may appear on the radar display. One of those echoes is the direct echo return from the target and the other is the secondary reflection return from a mast or funnel that stands in the same direction as shown in Figure 6.6. Radar scannerFunnelHLDirect microwaveSecondary reflectionof microwaveActual targetFalse echo from funnel Figure 6.6](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-309.png)
![6-10 6.4 False Echoesyyyyyy6 [IV] False Echo by Multiple Reflection When there is a large structure or ship with a high vertical surface near own ship as shown in Figure 6.7, multiple refection returns may appear on the radar display. These echoes appear in the same intervals, of which the nearest echo is the true echo of the target. Figure 6.7 [V] Second Time Echoes The maximum radar detection range depends upon the height of the scanner and the height of a target as described in the section of “The Horizon for Radar Beam Radiation”. If a so-called “duct” occurs on the sea surface due to a certain weather condition, however, the radar beam may propagate to a abnormally long distance, at which a target may be detected by the radar. For instance, assuming that the pulse length is MP3 (on the repetition frequency of 1400 Hz), the first pulse is reflected from a target at about 58 NM or more and received during the next pulse repetition time. In this case, a false echo (second time echo) appears at a position that is about 58 NM shorter than the actual distance. If the false echo appears at 5 NM on the radar display, the true distance of the target is 5+58=63 NM. On the pulse length is SP1 (on the repetition frequency of 2250 Hz), a false echo may appear at a position that is about 36 NM shorter than the actual distance. This type of false echo can be discriminated by changing over the range scale (the repetition frequency), because the distance of the target changes accordingly. If second time echo is appeared, the use of Economy mode in PRF menu is effective. Otherwise, Stagger Trigger menu set to on. (See section 3.8.3)](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-310.png)
![6-11 [VI] Radar Interference When another radar equipment using the same frequency band as that on own ship is near own ship, a radar interference pattern may appear on the radar display. This interference pattern consists of a number of spots which appear in various forms. In many cases, these spots do not always appear at the same places, so that they can be discriminated from the target echoes. (See Figure 6.8) HL HL Figure 6.8 If radar equipment causing an interference pattern and this radar are of the same model, their transmitting repetition frequency is nearly the same. As a result, interference patterns may be displayed concentrically. In this case, the interference patterns cannot be eliminated by using only the interference reflector function, so press [TX/PRF] key several times to fine-tune the transmitting repetition frequency. An interference suppressing effect can be heightened by applying a different transmitting repetition frequency to the interference pattern source radar and this radar.](https://usermanual.wiki/Japan-Radio/NKE1130.Users-Manual/User-Guide-1510228-Page-311.png)
