Advanced optimization for subarray structure in electronic warfare environment

Advanced Genetic Algorithm (AGA) is an algorithm that could be beneficial to both the jammer suppression and subarray structure, which could obtain an array structure with relatively concentrated subarray structure and better jammer suppression. The structure of subarray level optimization is analyzed and the signal model is presented. Subarray level optimization could suppress jammer effectively; compared with conventional genetic algorithm at subarray level (only adaptive processing in jammer), better subarray structure gained and the cost of hardware could be reduced remarkably. Simulation results demonstrate the validity of the introduced approach.
