摘　　要：在截获概率概念和截获条件的基础上,综合时域、空域、频域等窗口函数构建截获概率模型,分别建立截获过程的4个窗口函数子模型,研究截获概率与窗口函数变量的影响关系。以SPS-48雷达为辐射源,仿真分析各窗口函数变量对截获概率的影响程度,讨论分区策略下无源雷达参数优化对截获概率的影响并总结截获概率提高方法,为无源雷达设计、研制、试验以及使用提供技术支撑。Based on the concept and conditions of the probability of intercept,the model of probability of intercept is constructed by combining the window functions of time domain,area space and frequency domain.The four window function models are established and the influences of the probability of intercept and window function variables are studied. Taking the SPS-48 radar as an example,the influences of window function variables on the probability of intercept are simulated and analyzed.The effects of parameters optimization of passive radar on the probability of intercept are studied by a region search strategy and some methods for improving the probability of intercept are summarized,which can provide technical support for the design,development,test and use of the passive radar.
