Chapter 8 DETAIL PERFORMANCE SETTING 100 8-1-1 MAIN BANG SUPPRESSION (Usually, doesn’t need set up. adjust if necessary) This adjustment is decrease the transmitted signal which appears as a circular echo around the center. Adjustment is done so as to main bang is observe slightly seen. Excess adjusting is danger for nearest small target observation. If the main bang is not so big, use as factory setting.
Chapter 8 DETAIL RFORMANCE SETTING 101 8-1-2 TARGET EXPANSION Level setting. The level which can be set up is level 1, the level 2, the level 3, and the level 4. Expansion and the magnifying the observation target size.. Tap the “Level1, Level2, Level3, Level4“ icon. 8-1-3 GAIN LEVEL (Important adjustment. Since adjusted in factory, adjustment is not necessary in the field.)
Chapter 8 DETAIL PERFORMANCE SETTING 102 8-1-4 SEA CLUTTER LEVEL (Important adjustment. Since adjusted in factory, adjustment is not necessary in the field.)
Chapter 8 DETAIL RFORMANCE SETTING 103 8-1-5 RAIN AND SNOW CLUTTER LEVEL (Important adjustment. Since adjusted in factory, adjustment is not necessary in the field.)

Chapter 8 DETAIL RFORMANCE SETTING 105 8-2 TT(TARGET TRACKING) FUNCTION (Important adjustment. Since adjusted in factory, adjustment is not necessary in the field.) Vector shows the movement of the target. Vector Constant large. Vector is stable, but the response is slow. Vector Constant small. Vector is unstable, but the response is quick.. Tap Vector Constant, setting Bar appears lower part of screen. Set up by flick or tap + -. Rotary knob adjusting is possible. Click and set. Gate Display: The region automatically search target moving area. ON: Confirmation is possible under green searching area. OFF: Doesn’t display automatically searching area.
Chapter 8 DETAIL PERFORMANCE SETTING 106 Gate Size: Set up the region size which can search the moving target automatically. Wide region: Possible to track fast moving target, but many clutters are include. Sometime do miss tracking because of much noise. Narrow region Possible to track stable, but fast moving target are tend to lost. Because of first target soon goes outside of the region.
Chapter 8 DETAIL RFORMANCE SETTING 107 8-3 SCANNER FUNCTION 8-3-1 PULSE REPETITION FREQUENCY FINE TUNING (PRF ADJUST) When existing the same frequency radar, in the same area, they interfere each other. If p.r.f.(pulse reputation frequency)is the same, Interference can’t reject on the screen. In that case shift the p.r.f. a little may decrease the radar interference. PRF Fine Tuning: If radar interference cannot reject completely, it is effective way to shift the PRF. Watching the screen echo, rotate the Rotary knob and stop when radar interference are fade out from screen.
Chapter 8 DETAIL PERFORMANCE SETTING 108 8-3-2 STAGGER TRIGGER When existing the same frequency radar, in the same area, they interfere each other. If p.r.f.(pulse reputation frequency)is the same, Interference can’t reject on the screen. Another way to decease interference is shift the transmitting time randomly. Not synchronize signal which transmit randomly is eliminate. So decrease the other radar interference echo on screen. ON Stagger: Stagger trigger is generated OFF Stagger: Stagger trigger stop. (Normal trigger timing) Select and Tap . Watching the screen echo, select off or on when heavy radar interference on screen. return to the menu
Chapter 8 DETAIL RFORMANCE SETTING 109 8-3-3 SCANNER ROTATIONAL SPEED The rotational speed of inside microwave radiator is possible to change. The sensitivity of radar are low speed is more higher. So scanner rotation speed is possible to change according observing range. Every pulse length can select the Antenna rotation speed. Short range uses short pulse (SP). Medium range uses medium pulse (MP) Long range uses Long pulse (LP) Shorter range requires the High speed refresh screen. Longer range requires the Low speed for High sensitivity. User can select rotational speed according to his request.
Chapter 8 DETAIL PERFORMANCE SETTING 110 8-3-4 ECONOMY MAGNETRON SETUP (PRF , PULSE LENGTH) The life of magnetron proportion to the total transmitting pulse power. Low power transmission makes magnetron life more longer. Selection Normal: It is the usual factory setup. Usually, this is chosen. Economy: Selected the shorter pulse, repeat frequency is also selected lowest 650 Hz. The life of a magnetron keeps more longer time. Sensitivity is decrease somewhat from Normal. High Power: High sensitivity high performance. 8-3-5 TIMED TX The life of magnetron proportion to the total transmitting pulse power. Timed TX can save magnetron life longer. return to the menu Select and Tap
Chapter 8 DETAIL RFORMANCE SETTING 111 8-3-6 TUNE PEAK LEVEL Normally, adjustment is not necessary. (In case of adjustment the tuning peak point is shifted from maximum echo point.) This adjustment must be done with (8-3-7 Tuning indicator) alternately. Set RANGE at 24NM Display tuning level indicator menu. Tune maximum echo point. At this point adjust tuning level, so as to seen within the green bar. Adjusting data is 0 to 127 . 8-3-7 TUNE INDICATOR LEVEL Normally, adjustment is not necessary. (Adjust ,in case of tuning level is too low.) Set RANGE at 24NM Display the Tune Indicator menu. Tuning region is 0 to 127 NOTE! If tuning level is too excess setting, can’t work automatic tuning function. Adjust the tuning level bar moves within 80 to 90%.
