Abstract
In order to address the deployment and application of multiple jamming sources against adaptive nulling GPS antenna,this paper analyzes the basic principle and anti-jamming characteristics of power inversion algorithm based on the least mean square(LMS)to realize adaptive nulling.And then,aiming at the characteris-tics of poor convergence and limited number of anti-jamming sources when the eigenvalues of the autocorrelation matrix are dispersed,the paper proposes a jamming method of two-station strong and weak coordinative and multi-station joint suppression.The simulation results are shown as follows:The two-station strong and weak syn-ergistic jamming method has better jamming efficiency in the area near the two-station baseline,and in time of de-ployment and application,the power difference between strong and weak jamming sources and the power of weak jamming sources should be increased as much as possible.The multi-station joint jamming suppression method can effectively increase the effective area of jamming but has obvious discreteness,and in time of deployment and application,the number of the jamming sources and jamming power should be increased as much as possible.关键词
