摘要
本文描述了基于线性调频(LFM)信号的脉冲压缩雷达的基本原理,提出了基于LFM的脉冲压缩雷达检测多目标信号和提取多个目标信息的算法架构,并对此进行了实例仿真分析,着重讲述了根据雷达设计指标如何确定脉冲压缩雷达的技术参数和匹配滤波器的设计流程。实例分析说明脉冲压缩雷达具有高分辨力的多目标检测能力以及较小的测量误差,对提升作战雷达在复杂的战场环境下的多目标检测能力和抗干扰能力具有重要的意义。
In this paper,the basic principle of pulse compression radar based on linear frequency modulation(LFM)signal is described.An algorithm architecture for detecting multi-target signals and extracting multiple target information based on LFM-based pulse compression radar is proposed,and an example simulation analysis is carried out.It mainly describes how to determine the technical parameters of the pulse compression radar and the design flow of the matched filter according to the radar design index.The example analysis shows that the pulse compression radar has high resol ution multi-target detection capability and small measurement error,which is of great significance for improving the multi-target detection capability and anti-interference ability of combat radar in complex battlefield environment.
