摘　　要：脉冲压缩是一种现代雷达信号处理技术,能够有效地改善单一载频信号在作用距离和距离分辨率上的矛盾。快速发展的DSP芯片为提高雷达信号处理的实时性提供了良好的硬件平台。详细介绍基于多核数字信号处理器TMS320C6678实现对LFM信号进行实时脉冲压缩的并行流水的实现方法。理论分析和实现结果表明,多核并行流水方法能获得比普通单核更好的系统实时性。Pulse compression is an important technology of modern radar system. It can reduce the collision between operating distance and range resolution effectively. The developing DSP provides the hardware for raising efficiency of radar signal processing. This paper introduces the parallel implementation of pulse compression of LFM signals using DSP TMS320C6678,which is a digital signal processor based on multi-core, to compress LFM signal with pulse compression algorithm. Compared with the single core processing, parallel operation shows better real-time feature.
