摘要：

本文分析了并行Costas信号脉压方法，设计了基于“通用图形处理单元（GPGPU）”的处理模型，并基于“铺路爪”雷达参数实现了Costas信号的方案。该方案在8片Nvidia tesla C1060的异构系统上对5418个通道脉压处理耗时514.3 ms，比通用CPU处理系统速度提升574倍。研究结果对新一代异构高性能雷达信号处理系统的设计具有很好的参考意义。

Abstract:

This paper presents a general purpose graphics processing unit (GPGPU) based pulse compression processing model for parallel Costas signals. Our experiments demonstrate its performance and effectiveness. The processing model will provide a better reference for the design of a high-performance radar signal processing system.

Key words: high-speed radar signal processing, Costas signal, multi-velocity channel processing, general purpose graphics processing unit
