摘要
A space-time adaptive processing algorithm for delay tracking and acquisition of GPS signal with interference rejection capability is developed. The interference consists of both broadband and narrowband. The narrowband interferences are modeled as vector autoregressive processes and rejected by temporal whitening. The spatial nulling is implicitly achieved by estimating a sample covariance matrix and feeding its inverse into the extended Kalman filter. Computer simulations demonstrate the performance capability of the algorithm during severe jamming.
