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 fact that the quantitative evaluation method of anti-jamming ability is not given, the model of combined detection probability and false alarm rate is established. Based on the principle and flow of target detection by passive radar / infrared composite guidance, the theoretical detection threshold of dual-mode homing system was calculated by the likelihood ratio criterion, and the quantitative evaluation of composite guidance anti-interference ability was realized. The computer simulation verified that Applicability of the model. The simulation results show that the composite guidance has a strong advantage over the single guidance system in comparison with single-mode guidance. Theoretical analysis of the main conclusions of the composite guidance system detection threshold and other relevant parameters of the design guide.
