An Overview of Space-Time Adaptive Processing Technology Based on Sparsity of Space-Time Power Spectrum
摘要
Abstract
With the development of compressive sensing theory ,the space-time adaptive processing (STAP ) technology based on sparsity of space-time power spectrum (STPS) receives a growing interest .This paper firstly reviews the traditional STAP algorithms and shows analysis of sparsity of STPS from three different points of view and potential advantages of STAP technology based on sparsity of STPS .Then ,the current developed STAP algorithms based on sparsity of STPS are categorized into three class-es ,such as STAP based on prior knowledge of array manifold ,STAP based on sparse recovery of STPS and STAP based on both prior knowledge of array manifold and sparse recovery of STPS .It also performs an overview of those algorithms .Finally ,based on the progress of the existing research ,some key issues to enhance the performance of clutter suppression and moving target detection are introduced ,which include intrinsic mechanism analysis of sparsity ,space-time steering dictionary design ,easy parameters setting , fast and low complexity algorithms design ,robust algorithm design ,STAP algorithms based on sparse recovery of STPS design by exploiting different types of prior knowledge ,and constant false alarm rate detector design of STAP based on sparsity of STPS and validation using measurement data .关键词
