Abstract

Abstract:

In order to solve the problem that the direct matrix inverse(DMI) algorithm for clutter suppression can not be real-time processing in the passive radar engineering application, a segmented parallel DMI algorithm(called P-DMI) is proposed. By considering the feature of the DMI algorithm, the entire operation block is broken up into several identical sub-blocks, and in the Compute Unified Device Architecture, these sub-blocks are processed in parallel to achieve the purpose of improving the processing efficiency. Experimental results indicate that this algorithm's computation efficiency is raised more than 25 times compared with the traditional serial algorithm when the sampling rate is 200kHz and the clutter cancelation order is equal to 128. Also, the method has been used in real-time signal processing for passive radar successfully.
