摘　　要：通过对基于综合战场感知的射频辐射的研究,构建射频辐射风险评估指标体系,建立相关指标的计算模型。引进施里海尔截获因子,研究机载雷达天线空域扫描方式发生捷变对射频隐身性能的影响,得到截获率基本公式。分析发射机对截获接收机的照射时间,截获接收机的帧时间,无线波束的覆盖面积,接收机密度等参数的关系,得到截获率计算模型,在此基础上可进行风险评估和风险规避,为实现射频辐射隐身性的对策研究提供了理论依据。最后,以仿真算例验证截获率计算模型。By studying the radio frequency （RF） radiation based on synthetical battlefield sensing, the index system of RF radiation risk evaluation is constructed, and the computational model of the related indexes is con- stituted. The fundamental formulation of intercept probability is obtained by introducing the Schleher intercept factor and investigating the influence of the agile space scanning mode of antenna on a warplane RF stealth per formance. By analyzing the parameter relations among the irradiation time of transmitter, the frame time of in- tercepting receiver, the covering area of wireless wave cluster and the density of receivers, the computational model of intercept probability is obtained, and the risk evaluation and risk elusion based on the above results can be implemented, which provides the theoretical basis of accomplishing game investigation of RF radiation in stealth performance. Finally, the computational model of intercept probability is validated by the simulation ex- amples.
