ATA (Automatic Tracking Aid)

I ATA (Automatic Tracking Aid)

By tracking automatically the target chosen by the cursor key, the closest point of approach (CPA) and the time to

closest point of approach (TCPA) limit of a own ship and a target are calculated.

ATA is the function to tell about to alarm sound, when both CPA and TCPA becomes below a setting value (the ap-

proach watch area).

The range of the target which can be registered is taken as a target with a highest luminosity level of 0.2–16 miles.

•Max. 10 targets can be plotted on the screen.

•Plot positions shall be identiﬁed by an approved symbol mark (p. 20) and associated plot number.

•The vector origin will move across the screen at a rate and direction deﬁned by the calculated true or relative

course and speed.

•The vector will be displayed on the target.

•Display accuracy may increase by the self-ship and course change of target or acceleration, slowdown, etc.

BASIC RADAR THEORY

Radar uses a form of electromagnetic radiation, which like light, can be reﬂected. Because of this property, some

objects may cause false echoes on the screen where in fact no targets actually exist.

These echoes may appear if a large vessel, bridge, or tank is in proximity. Operators should be familiar with the ef-

fects of these phenomena. In some cases, echoes can be reduced.

I Side-lobe echoes

Radiation can escape on each side of the beam inside

the lobes. If a target reﬂects this radiation, it will be dis-

played on the screen as an echo.

Side-lobe echoes usually occur at short ranges and as

a result of large (strongly reﬂective) targets. They can

be reduced with proper adjustment of the

] control.

echoes

I Indirect echoes

Indirect echoes may be returned from either a passing

ship, or returned from a reﬂecting surface, such as a

mast on your own ship.

An indirect echo from a reﬂecting surface will appear

on a different bearing from the direct (true) echo, but

the distance will be approximately the same for both.

BASIC RADAR THEORY

I Multiple echoes

Multiple echoes may appear when a short-range and

strong echo is received from a ship, bridge, or break-

water.

Multiple echoes will appear beyond the target’s true

echo point on the same bearing of a large target. They

can be reduced with proper adjustment of the

[SEA]/[

] control.

See p. 10 for the [SEA]/[

] control.

I Minimum range

Detection at short range is very important. Minimum

range is determined primarily by transmitter pulse

length, vertical beam width and height of the scanner

unit. The shorter the transmission time, the quicker the

return echoes can be received and their distance mea-

sured.

The ability to see targets very close to the ship is de-

creased if the scanner is mounted too high off the

water, because the bottom of the vertical beam of the

scanner cuts off nearby targets.

Vertical beam width

BASIC RADAR THEORY

I Blind and Shadow sectors

Blind or Shadow sectors may exist because of ob-

structions such as masts, derricks or stacks. An ob-

struction may throw either a complete or partial

shadow as shown in the diagram below. If a target is in

a shadow sector, target echoes may not appear on the

screen.

When tall and massive targets such as a large island

are located at close range also shadowed without pro-

ducing any echoes. This phenomenon is called blind

sector. It is very important to know the bearings and

widths of all shadow sectors caused by your own

ship’s obstructions.

I Target resolution

Target resolution is determined by the horizontal beam

width and transmit pulse width. Sometimes it is difﬁcult

to detect two targets which are separated by short dis-

tances or which are in the same direction.

DDistance resolution

When two targets are separated by more than the

MAINTENANCE

Continued, reliable operation of the radar depends on how you care for your equipment. The simple maintenance

tips that follow can help you save time and money, and avoid premature equipment failures.

I Periodic maintenance

qKeep the equipment as clean as possible.

•Use a soft cloth to remove dirt, dust and water.

wCheck all hardware for loose screws, bolts, etc.

WARNING: BE SURE the power is OFF before

performing any maintenance.

eCheck cables and terminal connections.

I Scanner unit maintenance

cloth.

•DO NOT use strong solvents such as benzene or alco-

hol.

wCheck that there is no drift or caked salt.

•A heavy deposit of dirt or caked salt on the painted sur-

face of the upper scanner unit will cause a considerable

drop in radar performance.

eCheck for cracks or deterioration of the rubber

packing and replace it if necessary.

DPainting (MR-1000TII only)

To prevent the corrosion, paint the surface of the

scanner body (except the antenna unit) twice a year

or more.

DMounting

Check the mounting bolts of the scanner unit and

tighten if necessary.
