摘　　要：雷达信号的低截获概率技术体现于雷达系统的各个方面,其中波形设计是低截获概率技术的核心.对低截获概率波形的设计原则和验证方法进行了研究,提出了基于截获因子的在线计算方法和基于信号波形复杂度因子多因素分选与识别的方法.该方法能对多种设计的低截获概率波形进行评判,并给出正确的评判结论,对实际工程应用具有参考价值.The concept of Low Probability Interception（LPI） is very important in each part in designing Radar, and most of all, the wave design is the core. In this paper, we analyze the principle of designing LPI waves and the method of testing the designed waves＇ ability of anti-deinterleaving. We give a way of calculating the intercept factor and a de-interleaving method based on the complexity of designed waves. It is convenient to test many kinds of LPI signals＇ performance, with accurate and useful results given.
