Amplitude Angle Monopulse Estimation for the Four-Channel Hybrid Polarimetric Radar System

In this letter, the regular amplitude angle monopulse estimation method is proven not suitable for polarimetric radars because it sets up correlation between azimuth angle and elevation angle of the target and can result in low accuracy. To solve this problem, the polarimetric amplitude angle monopulse estimation method is proposed to obtain the correct angle. By changing the channel synthesis method when the radar receives the signals, the proposed method shows a higher accuracy than the regular method through formulation and the experiment results.
