A research of robust GPS anti-jamming scheme
|
Abstract:
In order to solve the problem of GPS anti-jamming performance degradation in the condition of small sample support, a novel scheme of iteration correlation subtraction algorithm-multistage wiener filter(ICSA-MWF)based on adaptive diagonal loading is proposed. The scheme is a new solution of adaptive anti-jamming by analyzing ICSA-MWF's recursion process based on making full use of the jam and noise's eigenvalue information provided by ICSA-MWF. The experiment results show that the diagonal loading factor is adjusted adaptively, the robust of GPS anti-jamming is increased largely, and the computational burden is reduced by using the novel method. The real-time property of anti-jamming is enhanced.
