摘要
现代雷达波形既要满足探测性能还得具有一定的反截获性能。文章提出了一个用来分析波形反截获性能的指标，然后重点分析了线性调频信号，Costas信号，二相编码信号和Frank多相编码信号这几种传统雷达波形的反截获性能。未来雷达波形设计会向着组合调制和随机信号等方面发展。
Modern radar waveform should not only meet radar detection performance requirement but also has certain anti-interception performance. In this paper, an index used to ana- lyze the anti-interception performance of waveform is introduced. Then, the anti-interception performances of several conventional radar waveforms, such as the linear frequency modulated （LFM） , the Costas waveform, Barker code waveform and Frank coded waveform are analyzed. The future radar waveform design will develop towards the combination of modulation and random signals aspect.
