摘要
从电子对抗中雷达信号侦察的角度出发,介绍了现代采用的五种分析方法——时域、频域、调制域、谱相关和时-频分布,并对这五种方法进行了简要的原理分析,分析表明它们是侦察雷达信号的有效手段。最后对雷达诱饵为保护雷达所应具有的信号特征提出了一些看法。
In this article,from the point of view of radar signal detection in ECM,we introduce five kinds of signal analysis methods,including time domain,frequency domain,modulation domain, spectral correlation and time-frequency distribution. And then we analyze their principles in brief. The results indicate that they are effective for detecting the radar signals. At the end,we discuss some opinions about the signal feature of decoy used for protecting radar.
