Abstract
Joint space-time adaptive process (STAP) is an advanced interference suppression method for GNSS receiver. The STAP method based on power inversion (PI) and beam forming (BF) optimal criterion is widely used. We usually hope that anti-jamming processing not only null the interference direction, but also beam forming the satellite signal for antenna array processing gain. But satellite signal is too weak to hardly estimation the direction of arrive (DOA), and the estimation error cause anti-jamming performance drop quickly. Aim at this problem, a joint space-time anti-jamming method based on Maximum CNR criterion is proposed. Firstly, we use PI method to suppress interference primarily, and acquisition and tracking to get the desired code spread signal, and estimate the satellite signal direction vector. Then we compare the output CNR of PI and BF method, control the output to maximum the CNR of output signal. The proposed method not only avoid the complexity of traditional satellite DOA estimation, but also overcome the performance loss by the estimation error. The performance is much better than PI and BF method and the complexity is simple, it is benefit for engineer realization.
