Array sparse anti-jamming algorithm for satellite navigation terminals
Aiming at the problem of excessive computation in engineering applications for space time joint processing that is a commonly used technical means for anti-jamming of navigation terminals,the paper proposed a spatial correlation coefficient-based sparse algorithm for airtime array:antenna subsets combined with spatial correlation coefficients were used to maximize the spatial separation of signal and interference,and the optimal antenna subset was obtained by Taylor approximation.Simulational results showed that the performance of the sparse array obtained by the proposed algorithm could approximate the full array,while its computational effort would be 34.3%of the full array.
