Abstract

Abstract:

In order to reduce the computational burden of space-time processing filter groups, a space-time processing filter groups designed method is proposed. This method can be easily implemented owing to low computational complexity and modular structures. Under the strong jamming scenario a cascaded space-time adaptive processing scheme is deviced with its first stage as ordinary space-time adaptive processing with a certain constraint and the second stage as the beam former aided with information extracted from the cyclic-covariance matrix. Experiments show that such a cascaded scheme could bring signal-to-noise-ratio improvement for the space-time processing.

Key words: cyclostationarity, space-time processing, interference suppression, QR decomposition
