摘要：
A fast Conjugate-Gradient Iterative Algorithm (CGIA) for solving optimal space-time adaptive processing (STAP) problem is proposed in this paper. The algorithm is based on FFT by exploring Block Toeplitz with Toeplitz Block (BTTB) structure of the interference covariance matrix. Therefore computational complexity is significantly reduced as compared with the matrix inversion method. Computer simulations are provided for illustrating the effectiveness of the proposed method.
