摘　　要：针对传统的抗干扰能力评价方式没有给出定量的情况,建立了复合制导系统联合探测概率与虚警率的模型。以被动雷达/红外复合制导对目标检测基本原理与流程为基础,利用似然比准则计算双模寻的系统的理论检测阈值,实现了复合制导抗干扰能力的定量评价,并通过计算机仿真验证该模型的适用性。仿真结果表明:与单模制导相比较,复合制导较单一制导体制具有很强的优势。理论分析所得到的主要结论对复合制导系统探测门限及其它有关参数的设计具有指导意义。In view of the problems of traditional performance evaluation without quantification,target detection probability and false probability mathematics model of dual-model compound seeker were founded.Based on the principle of detection and process of the Passive Radar/IR dual-model compound seeker,the likelihood ratio criterion was used to computer the liminal value of dual-model compound seeker,quantificational evaluation of the anti-jamming ability was realized,the applicability of which is validated by computer simulations.Simulation results show that dual-model compound guidance method has great advantages over single model guidance method alone.Conclusions drawn from the theoretical analysis are benefitial to the design of thresholds and other related parameters.
