- With own ship at zero speed, an antenna height of 15 m above the sea level and in calm conditions, the navigational buoy in Table should be detected at a minimum horizontal range of 40 m from the antenna position and up to a range of 1 NM, without changing the setting of control functions other than the range scale selector.
- Compensation for any range error should be automatically applied for each selected antenna, where multiple antennas are installed
RANGE & BEARING DISCRIMINATION
Range and bearing discrimination should be measured in calm conditions, on a range scale of 1.5 NM or less and at between 50% and 100% of the range scale selected:
Range
The radar system should be capable of displaying two point targets on the same bearing, separated by 40 m in range, as two distinct objects.
Bearing
The radar system should be capable of displaying two point targets at the same range, separated by 2.5° in bearing, as two distinct objects
ROLL AND PITCH
The target detection performance of the equipment should not be substantially impaired when own ship is rolling or pitching upto +/-10°.
