摘要

A new method to extend the satellite navigation anti-jamming degree of freedom based on synthetic aperture is proposed. In this paper, by means of using the motion characteristics of single antenna, the time-domain sampling of signal is converted into spatial sampling and virtual array is synthesized. When the number of virtual elements in the array is limited, the number of interferences which can be suppressed can be greatly increased, which can solve the problem that the freedom of anti-interference is limited by the number of elements. Combined with the optimal anti-jamming weighting criterion, the space-frequency anti-jamming algorithm is used for anti-jamming processing, and the covariance matrix broadening algorithm is used to optimize the anti-jamming processing results, which solves the problem of how to deal with robust anti-jamming under the condition of unfixed anti-jamming degree of freedom. The simulation results verify the effectiveness of the method.
