Angle-of-Arrival Estimation Error for Shipboard Monopulse Radars

Abstract

Angle estimates by shipboard monopulse radars are corrupted by sea- reflected multipath. It is shown that even though the elevation and azimuth estimates in antenna coordinates are badly corrupted for conditions of crosslevel and sea-reflected multipath, the azimuth error in the plane of the sea may be tolerable. The azimuth errors in the plane of the sea are often less than 0.1 beamwidth. The errors were studied under a variety of conditions and the effect of scanning off axis as in a phased array was also included.
