Abstract

Radar Signal Processing is a very important aspect of Radar systems. Pulse Compression Technique is a Signal Processing Technique used in Radar systems to avail the benefits of large range detection capability of long duration pulse and high range resolution capability of short duration pulse. But at the output of Pulse Compression filter, sidelobes are present and these unwanted outputs may mask a weaker target which is present nearer to a stronger target. Hence, these sidelobes affect the performance of the Radar detection system. In this paper, focus is given on which technique achieves less number of sidelobes, narrow mainlobe width, better range resolution and low Peak Sidelobe Level (PSL) under various Doppler shift, multiple target environment and noise conditions,. For these purposes, the three very important Radar Pulse Compression techniques, Polyphase, Biphase and Linear Frequency Modulated (LFM) Codes are discussed in detail. Simulations are carried out to know the effectiveness of the Codes used in the Pulse Compression Signal Processing Techniques of Radar.

雷达脉冲压缩信号处理技术的有效性

雷达信号处理是雷达系统的一个重要方面。脉冲压缩技术是一种用于雷达系统的信号处理技术，它利用了长持续脉冲的大距离探测能力和短持续脉冲的高距离分辨能力。但在脉冲压缩滤波器的输出，副瓣是存在的，这些不需要的输出可能掩盖了一个较弱的目标，这是更接近于一个更强的目标。因此，这些副瓣会影响雷达探测系统的性能。本文重点研究了在各种多普勒频移、多目标环境和噪声条件下，哪种技术能实现旁瓣数量少、主瓣宽度窄、距离分辨率高、峰值旁瓣电平低的特点。为此，详细讨论了三种非常重要的雷达脉冲压缩技术:多相、双相和线性调频码。通过仿真验证了这些编码在雷达脉冲压缩信号处理技术中的有效性。
