Considering the real-time requirement of interference suppression in INS-assisted GPS (GPS/INS) receiver, a novel adaptive interference suppression approach for the GPS/INS receiver is presented based on the Kalman filter.An adaptive generalized sidelobe canceller (GSC) always employs the least-mean-square (LMS) algorithm for weight adaptation due to the lower complexity, but its convergence rate is lower and even make the receiver interrupt in severe cases. First, Householder transformation is employed for the design of the blocking matrix of the GSC, which can block desired signal received by an arbitrary planar array type. Then, update the adaptive weight on the low path by the Kalman filter, which exhibits great advantage for the output signal-to-interference-noise ratio (SINR). Theoretical analysis and simulation results demonstrate that the proposed method can effectively suppress the impact of interference on the receiver,and improve real-time characteristics of interference mitigation.
