摘　　要：反辐射导弹的迅速发展对雷达构成了极大的威胁,研究切实可行的反辐射导弹对抗措施显得十分迫切。首先介绍了低截获概率雷达的定义;然后推导出低截获概率方程,得到雷达截获因子公式;最后根据截获因子公式,以扩谱技术、脉冲压缩和脉冲积累为例,论述低截获概率技术对抗反辐射导弹的有效性,并分别进行了仿真分析。这为雷达对抗反辐射导弹的提供了理论指导。The fast development of antiradiation missile （ARM） has posed a great threat to radar, and thus it is urgent to find a new effective countermeasure against ARM. First the definition of low prob- ability of intercept （LPI） radar is introduced; then the equation of LPI and intercept formula are derived; finally, according to the intercept formula, and the effectiveness is verified with examples of spreading spectrum technique, pulse compression and pulse accumulation. This research has certain theoretical val- ue for studying countermeasures against ARM.
