2. DESCRIPTION OF RADAR

2.1 General

2.1.1 Minimum and maximum ranges

Minimum range

The minimum range is defined by the shortest distance at which, using a scale of

0.0625 or 0.125 nm, a target that has an echoing area of 10 m2 is shown separate from

the point that shows the antenna position.

The minimum range depends on the pulselength, antenna height, and signal process-

ing (like main bang suppression and digital quantization). Use a shorter range scale

as far as it gives favorable definition or clarity of picture.

Maximum range

The maximum detection range, Rmax, changes depending on the height of the anten-

na, the height of the target above the sea, the size, shape and material of the target,

and the atmospheric conditions.

Under normal atmospheric conditions, the maximum range is equal or a little shorter

than the optical horizon. The radar horizon is longer than the optical one by approxi-

mately 6%, because of the diffraction property of the radar signal. The Rmax is shown

in the following formula.

If the height of the antenna is 9 m and the height of the target is 16 m, the maximum

radar range is;

Note: The detection range is reduced by any precipitation (which absorbs the radar

signal).

2.1.2 Radar resolution

The bearing resolution and range resolution are important in radar resolution.

Bearing resolution

The bearing resolution is the ability of the radar to display the echoes received from

two targets at the same range as the separate echoes. The bearing resolution is pro-

portional to the antenna length and the wavelength.

Bearing resolution

Range resolution

The range resolution is the ability to display the echoes received from two targets on

the same bearing as separate echoes. The range resolution is calculated by only

pulselength.

The test targets used to calculate the range and bearing resolution are radar reflectors

that have an echoing area of 10 m2.

2.1.3 Bearing accuracy

One of the most important features of the radar is how accurately the bearing of a tar-

get can be measured. The accuracy of bearing measurement depends on the narrow-

ness of the radar beam. The bearing taken is relative to the heading of the ship.

Correct adjustment of the heading line at installation is important to get accurate bear-

ings. To minimize the error when you measure the bearing of a target, put the target

echo at the extreme position on the screen by selecting a suitable range.

2.1.4 Range measurement

Measurement of the range to a target is important function of the radar. There are

three methods to measure range: the fixed range rings, the Variable Range Marker

(VRM), and the cursor (if the cursor is set to measure range and bearing). The fixed

range rings appear on the screen with a given interval and provide a rough estimate

of the range to a target. The diameter of VRM is increased or decreased so that the

marker touches the inner edge of the target (see paragraph 1.15.2). The VRM is a

more accurate range measurement than the fixed range rings. For cursor, see

section 1.13.

2.2 False Echoes

The echo signals can appear on the screen at positions where there is no target or

disappear when there are targets. These false echoes are shown below.

2.2.1 Multiple echoes

Multiple echoes occur when a transmitted pulse returns from a solid object like a large

ship, bridge, or breakwater. A second, a third or more echoes can be seen on the dis-

play at double, triple or other multiples of the actual range of the target as shown be-

low. You can reduce and remove the multiple reflection echoes with the A/C SEA

control.

2.2.2 Sidelobe echoes

When the radar pulse is transmitted, some radiation escapes on each side of the

beam, called "sidelobes”. If a target is where a target can be detected by the sidelobes

as well as the mainlobe, the side echoes can be shown on both sides of the true echo

at the same range. Sidelobes show normally only on short ranges and from strong tar-

gets. You can reduce the sidelobes with the A/C SEA control.

2.2.3 Virtual image

A large target close your ship can appear at two positions on the screen. One of them

is the true echo reflected by the target. The other is a false echo which is caused by

the mirror effect of a large object on or close your ship as shown in the following figure.

If your ship comes near a large metal bridge, for example, a false echo can temporarily

appear on the screen.

2.2.4 Shadow sector

Funnels, stacks, masts, or derricks near the antenna interrupt the radar beam, and a

non-detecting sector can occur. Radar can not detect targets within this sector.

2.3 SART (Search and Rescue Transponder)

2.3.1 SART description

A Search and Rescue Transponder (SART) responds to any X-band (3 cm) radar with-

in a range of approximately 8 nm. Each radar pulse received causes the SART to

transmit a response which is swept continuously across the complete radar frequency

band.

2.3.2 General remarks on receiving SART

SART range errors

When the SART is at a range greater than approximately 1 nm, the first dot is dis-

played at 0.64 nm past the true position of the SART. When the range closes so that

the fast-sweep responses are also seen, the first range echoes are displayed at 150

m past the true position.

Range scale

When you find the SART position, do as follows:

1. Use the RANGE key to set the range scale to 6 nm or 12 nm.

2. Turn off [A/C Auto].

3. Turn off [Int Rejector].

SART display

To display only the SART echo clearly on the radar screen, reduce the tuning on man-

ual mode. The normal radar echoes get weak, but the SART echoes remain. Your ship

comes near the SART, the arc for the SART display becomes larger. Most of the radar

screen becomes fuzzy. Adjust the A/C SEA and GAIN controls to display the neces-

sary screen.

2.4 RACON

The RACON is a RAdar beaCON which sends radar-receivable signals in the radar

frequency spectrum (X- or S-band). There are several signal formats; in general, the

RACON signal appears on the radar screen as an echo in the shape of a rectangle

originating at a point just past the position of the radar beacon. It has a Morse coded

pattern. Note that the position on the radar display is not accurate.

3. ARPA OPERATION

The Automatic Radar Plotter ARP-11 (option) manually or automatically acquires and

tracks ten targets. When a target is acquired automatically or manually, a target is au-

tomatically tracked within 0.1 to 16 nm.

3.1 Precautions for Use

3.2 Controls for Use with ARPA

ENTER: Acquire the cursor-selected target. Display data for tracked target (in the data

box at the bottom of the screen).

CANCEL/HL OFF: Remove data of cursor-selected tracked target from the data box.

Stop tracking the cursor-selected target (when its data is not displayed in the data

box).

MENU: Access the [Target] and [ARPA] menus for ARPA operations.

CursorPad: Select a target to acquire (or cancel the tracking). Select a target to show

(or remove) target data.

Do not depend on one navigation device

for the navigation of the ship. The

navigator must check all aids available

to confirm position. Electronic aids are

not a replacement for basic navigation

principles and common sense.

· The ARPA automatically tracks an

automatically or manually acquired radar

target and calculates its course and

speed, indicating them by a vector. Since

the data from the auto plotter depend on

the selected radar targets, the radar must

be optimally tuned for use with the auto

plotter, to ensure required targets will not

be lost or unnecessary targets like sea

returns and noise will not be acquired

and tracked.

· A target is not always a landmass, reef,

ship, but can be returns from the sea

surface and clutter. As the level of clutter

changes with the environment, the

operator must correctly adjust the A/C

SEA, A/C RAIN and GAIN controls so

that the target echoes do not disappear

from the radar screen.

The plotting accuracy and response of

this ARPA meets IMO standards.

The tracking accuracy is affected by the

following:

· The tracking accuracy is affected by

course change. One to two minutes is

required to restore vectors to full

accuracy after a sudden course change.

(The actual amount depends on

gyrocompass specifications.)

· The amount of tracking delay is inversely

proportional to the relative speed of the

target. Delay is on the order of 15-30

seconds for high relative speed; 30-60

seconds for low relative speed.

The display accuracy is affected by the

following:

· Echo intensity

· Pulse width of radar transmission

· Radar bearing error

· Gyrocompass error

· Course change (your ship or target)

The ARPA target symbol changes over time as shown below. A vector which indicates

the motion direction of the target appears approximately one minute after the acquisi-

tion.

ARPA target symbol

Target number

[River] and [Sea] (Non-IEC system): An acquired target gets the youngest unused

number. When a target is lost and disappears from the number list, the next acquired

target takes the number of that lost target (ie: In a five-target list, if the target 2 is lost,

the next acquired target takes the number of target 2).

[IEC] and [Russian-River] (IEC system): An acquired target gets the youngest un-

used number. When a target is lost and disappears from the number list, the next ac-

quired target takes the next sequential number until reaching a maximum 10. If the

target number reaches a maximum 10, the next acquired target takes the number of

a previously lost target.
