摘　　要：为解决对雷达组网的多机协同噪声干扰的资源分配优化问题,用全程发现概率作为噪声干扰效果评估指标,建立了资源分配优化模型.首先根据信噪比经验公式,提出了利用雷达接收信噪比估算单站发现概率来获得全程发现概率的多机协同噪声干扰效果评估方法.其次建立了固定航迹下多机协同噪声干扰的全航程资源分配优化模型,解决了航线过程中分配方案产生变化而影响干扰效果的问题,同时给出了利用改进遗传算法对该模型求解的步骤.最后进行了仿真,仿真结果验证了该模型在不同干扰机及雷达数目情况下的有效性.In order to solve the problem of resource allocation optimization for multi-jammer cooperative noise jamming in radar network, this paper uses the whole process detection probability as the evaluation index of noise jamming effect to establish an optimization model of resource allocation. Firstly, based on the empirical formula of SNR, the paper proposes the method of evaluating the probability of multi-jammer cooperative noise jamming, in which method to obtain the whole process detection probability, radar received SNR is used to estimate the discovery probability of a single radar station. Secondly, the paper establishes a resource allocation optimization model of the whole range of multi-jammer cooperative noise interference under a fixed track, and solves the problem of the flight course change affecting the jamming effect; at the same time the paper also gives the steps of using improved genetic algorithm to solve the model. Finally, the simulation results show the effectiveness of the proposed model with different types of jammer and different number of radar sets.
