Adaptive clutter suppression for non-side-looking airborne phased array radar

The clutter suppression methods of spatial-temporal adaptive signal processing for non-side-looking airborne phased array radar is studied. On analyzing the non-side-looking spatial-temporal clutter distribution properties, three practical processors are presented based on spatial and temporal repetition structure. Spatial element repetition cascade temporal pulse repetition structure followed by adaptive processing is a practical spatial-temporal adaptive signal processing method. It can achieve sub-optimum performance by using element and pulse signal information more efficiently.
