US Patent 10243761 Scalable space frequency adaptive processing (SFAP)

Embodiments of the inventive concepts disclosed herein are directed to systems and methods for signal processing. An antenna array can receive signal information. A signal processing device can perform a time-domain-to-transform-domain transform with N transform domain bins, on the signal information. The signal processing device can determine N covariance matrices each corresponding to a respective one of the N transform domain bins. The signal processing device can group covariance matrices from the N covariance matrices into groups of M covariance matrices. Each group can correspond to a respective group of M adjacent bins from the N bins. The signal processing device can produce a combined spatial covariance matrix for each group of M covariance matrices, by performing a weighted combination of covariance matrices within the respective group of M covariance matrices. The signal processing device can calculate spatial weights from each of the spatial covariance matrices, for anti-jamming processing.
