1.6 RADAR Accuracy
Background
The correct measurement of a target position by radar is determined by the bearing and range accuracy
of the radar system. Both parameters are depending on physics, on installation, and on the ability of the
user to read accurate values from the screen.
As far as the physics is concerned, the accuracy of bearing measurement basically depends on the
narrowness of the radar beam. The radar beam for X-band has a horizontal beam width of 1.5° with the
5 foot antenna and 0.95° with 8 foot antenna. For S-band the corresponding value is 1.8° with 14 foot
antenna. These values describe the 3 dB corners on each side of the beam, where the transmitted power
is half of the centre value. Experience shows, that typically at sea these values are doubled. So the prac-
tical beam width of an 8 foot X-band antenna is about 2°. It provides an echoe with a size of:
-> 6 nm x sin 2° = 387 m
Further on physics is involved with range measurement. It depends on the pulse rate and length which
are determined by the user selected range. To minimize error when measuring the range of a target, put
the target echo at an outer position on the screen by selecting a suitable range.
In terms of installation the bearing is usually taken relative to the ship's heading, and thus, proper
adjustment of the heading line at installation is an important factor in ensuring bearing accuracy.
Finally the user aspect has to be considered. To minimize error when taking the bearing of a target from
screen, put the target echo at an outer position on the screen by selecting again a suitable range.
Results
According to IMO (MSC.192/5.2) the radar system range and bearing accuracy shall be as follows:
• "Range: within 30 m or 1 % of the range scale in use, whichever is greater;
• "Bearing: within 1°
in typical operational and environmental conditions.
A well adjusted

Platinum RADARpilot is exceeding these requirements as follows:
• "Range: within 15 m or 0.3 % of the range scale in use, whichever is greater;
• "Bearing: within 0.5°
in typical operational and environmental conditions.
