Abstract

The invention belongs to phased array radar array processing technology, and relates to a subarray weight value determination method for phased array radar difference beam side lobe suppression. The steps to determine the subarray-level weight value are as follows: encode the subarray weights that suppress the sidelobe of the difference beam, and establish an initial population; perform genetic optimization; perform the second stage of genetic optimization; decode the obtained optimal individual, and output Subarray weighting. The invention proposes a sub-array-level weight value determination method for phased array radar differential beam sidelobe suppression, which omits a large number of analog microwave devices, simplifies the array structure, and reduces hardware costs.

Description

Method for Determining Subarray Weighted Values ​​of Differential Beam Sidelobe Suppression in Phased Array Radar technical field The invention belongs to phased array radar array processing technology, and relates to a subarray weight value determination method for phased array radar difference beam side lobe suppression. Background technique Phased array radar has important application value in the field of national defense. A digital receiving channel (including frequency mixing, amplification, filtering and A / D conversion, etc.) is connected behind each array element of phased array radar to obtain the digital array Phased array radar. It adopts array signal processing technology, so that many advanced array processing methods can be applied, so that the performance of phased array radar is greatly improved. The digital array phased array radar has incomparable advantages over the traditional phased array radar, which greatly improves the information detection and pro...
