弱小信号雷达目标的信噪比分析及提高方法

Analysis of puny signal target's signal process method

对付弱小信号的雷达目标,如何提高信噪比(SNR)是信号处理的主要工作,也是成功检测目标的重要保障。本文通过对信号处理系统的仿真,分析信号处理对弱小信号目标回波的信噪比改善以及各环节的信噪比损失情况。

To deal with the puny signal target, it is important to improve the signal-to-Noise （SNR） which can ensure the detection well. According to the simulation of the signal process system, analyzing the improvements of SNR from puny signal of targets echo and reducing the influence to SNR from other modules are presented.
