Abstract
The aim of this paper is to propose a joint STAP-WVD based slowly moving target detection and imaging approach for airborne phased array SAR system. The difference of models of received echoes backscattered from extended scene and point like moving target between SAR and AEW system is investigated and it shows the quadric phase can not be ignored in SAR system like that in AEW system for its long coherent processing period. A modified STAP is put forward to suppress the clutter while retain the phase history of the moving target. The concept of the `weight signal' was proposed to retrieve the phase history of the moving target, which was damaged by the STAP due to the optimum SAR clutter cancellation. The computer simulation results, which lend support to the conclusions reached through theoretical analysis, were presented throughout the paper.
