Parallel Implementation of Sliding Extensive Cancellation Algorithm for Passive Radar System
摘要
Abstract
Cancellation of clutter is one of the key signal processing techniques in passive radar.Sliding extensive cancellation algorithm (ECA-S) has broken through the limitations of extensive cancellation algorithm batches (ECA-B) in the number of batches during realdata processing.By adding a sliding window to each segmented signal,a sufficient integrated time is ensured while the number of batches is increased,and a batter filtering effect is obtained.However,this improvement is achieved at the cost of increasing the space and time complexity.Considering the advantages of graphic processing unit (GPU) in high memory throughput,parallel processing,and computationally intensive problem,this paper proposes a parallel realization of ECA-S algorithm based on GPUs.The experimental results verify the effectiveness of the proposed algorithm.It also meets the demands of real-time processing.关键词
