A Study of Real-Time Spatial-Filtering Algorithm for Missile-Borne Phased-Array PD Radar Target Detection

For application of missile-borne phased-array pulse-Doppler radar target acquisition and detection, a novel sub-array based spatial filtering algorithm of side-lobe clutter suppression is presented. The algorithm evidently lowers the computation by using reduction of dimensionality in azimuth and pitch direction with reasonable losses in performance of clutter suppression.
