摘要
The present invention describes a space-time adaptive processing (STAP) system and method combining adaptive processing with automatic phase calibration providing an improved signal-to-noise ratio of a received signal. The adaptive processing is accomplished by calculating a reduced rank approximation of a factorization of a covariance matrix via a partial singular value decomposition of the data matrix. According to the present invention, the calculation of a white noise gain constraint does not require knowledge or estimation of the noise floor. Automatic phase calibration using the signal data as the calibration source combined with the adaptive processing according to the present invention provides and enhance signal-to-noise ratio and clutter suppression.
