The DOA Estimation Algorithm of Ship Swing Based on Ship-borne Radar

With the continuous development of radar signal research, there are mature theories to measure target azimuth. Virtual interpolation is one of the valid solutions that could improve the measurement result. Actually, the fluctuation of the sea surface will affect the radar’s monitoring of the target. Therefore, in order to estimate the target angle in complex sea state, this paper will focus on the influence of ship-borne swinging target.
