Radar signal waveform and target angle joint estimation method under non-Gaussian noise

Abstract

The invention discloses a radar signal waveform and target angle joint estimation method under non-Gaussian noise. The method comprises the steps of acquiring echo signals collected by a radar array antenna under the non-Gaussian noise, wherein the non-Gaussian noise is pulse noise and echo data abnormal values; according to the echo signal, performing optimization target processing on the echo signal to obtain an optimization target processing result; and obtaining a waveform and a target angle of the echo signal according to the optimization target processing result. According to the embodiment of the invention, the radar signal waveform and the target angle are estimated at the same time under the non-Gaussian noise background, and the imaging characteristics of the target can be obtained while the position of the target is accurately estimated.
