Research on extraction method of flat gain characteristics of multi-channel radar antenna

Abstract

The beam flatness gain of multichannel radar antenna is an important auxiliary characteristic in the process of target detection and recognition. Active multi-target jamming is a typical method to extract flat beam gain of multi-channel radar antenna. It affects the detection, tracking and recognition ability of phased array radar, and also affects the judgment of phased array radar on the status. In order to improve the detection ability and networking ability of phased array radar, this paper optimizes the extraction method of beam flattening gain characteristics of multi-channel radar antenna under the background of accurate main lobe interference, so as to ensure the normal operation of radar antenna device. Finally, the numerical simulation is carried out. Experimental results show that this method can effectively suppress active multi-target interference. This conclusion is of great significance to improve the detection ability of radar in complex electromagnetic environment.
