Study on satellite adaptive nulling antennas with hybrid genetic algorithm

Abstract

Combining genetic algorithm with LMS,a hybrid genetic algorithm（GALMS）for satellite adaptive nulling antenna beam space was proposed.The hybrid algorithm performance of various parameter selections was studied.At last a simultaneous parameter adaptation scheme was introduced.The scheme could reduce difficulty and improve effi-ciency of parameter selection and can dynamically adjust the parameters for better anti-jamming performance.
