摘　　要：针对传统的评价方式没有考虑在有干扰时性能变化的情况,建立了复合制导系统在有干扰和无干扰情况下的检测率与虚警率的模型。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。In view of the problems of traditional evaluation without jamming, target detection probability and false probability mathematics model of dual-model compound seeker are founded on jamming and no jamming period. Use object detection principle and process of passive radar/ infrared compound guidance as base, and adopt likelihood ratio principle to calculate the liminal value of dual-model compound seeker, realize quantificational evaluation of the anti-jamming ability, 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.
