Anti-interference method for navigation receiver

The invention provides an anti-interference method for a navigation receiver. The method comprises the following steps: respectively carrying out space-time adaptive anti-interference processing on each digital beam by adopting a blind digital multi-beam forming technology; performing space-time null widening processing on each digital beam to obtain a data covariance matrix after null widening; and performing signal distortion processing to correct the steering vector of the target satellite. According to the method, the anti-interference freedom degree can be effectively improved, navigation signal distortion is avoided, a high-dynamic environment and various non-ideal factors (array errors, mutual coupling, channel amplitude-phase inconsistency and the like) can be effectively handled, and gains of different satellites are remarkably improved, so that the working robustness and navigation positioning precision of a satellite navigation receiver in a complex environment are remarkably improved. 本发明提供一种导航接收机
