摘　　要：为解决有源欺骗干扰条件下天波雷达抗干扰能力的定量评估问题,根据天波雷达特点和雷达信号截获的必要条件,建立了截获概率模型。采用灰色度量方法估算了天波雷达抗欺骗性干扰措施有效概率。给出了分选识别概率、模拟雷达信号概率和干噪比达到要求的概率计算模型,在此基础上,构建了天波雷达抗欺骗性干扰概率评估模型。应用模型对金达莱天波雷达系统在典型条件下抗欺骗干扰能力进行了评估,从而验证了评估模型的可行性和有效性。To solve the problem of quantitative evaluation of sky-wave radar anti-jamming capability under active deception jamming conditions, an intercepting probability model was established based on the characteristics of sky-wave radar and necessary conditions for intercepting radar signal. The effective probability of sky-wave radar anti-deception jamming measures was estimated by using the grey measurement method, and models were given for calculating the sorting and identification probability, the probability of simulating radar signals and the probability that interference-to-noise ratio met the requirement. On which basis, a model for evaluating the sky-wave radar anti-deception jamming probability was established. The anti-deception jamming capability of Azalea sky-wave radar system was evaluated under typical conditions by use of this evaluation model, thus confirming its feasibility and validity.
