防空情报雷达反干扰能力综合分析和评估

摘要

Aiming at the problem of evaluation of air defence surveillance radar anti-jamming performance in complex electromagnetism circumstance, the paper analyzes the method and rule of radar anti-jamming performance evaluation. According to the characteristics of air defence surveillance radars and the method of multiattribute decision-making, the evaluation model of anti-jamming is built based on synthesizing five radar attributes:resolution, power, frequency, system and anti-jamming technical measures. In the assumptive jamming circumstances, the model is applied to the anti-jamming performance evaluation of three kinds of air defence surveillance radars. The result of the model can reflect the practical situations because of considering all kinds of attributes about anti-jamming performance. The model is valuable in practice.%针对在复杂电磁环境下防空情报雷达反干扰能力评估难的问题,分析了雷达反干扰能力评估的方法和准则,根据防空情报雷达自身特点,依据多属性决策方法,分别建立了分辨率、功率、频率、雷达体制和反干扰技术措施五个属性的评估模型,在此基础上建立了反干扰能力综合评估模型.在想定干扰环境下,应用评估模型对三种不同型号防空情报雷达的反干扰能力进行了计算.评估模型考虑了影响防空情报雷达反干扰能力的各种因素,所得结果能准确地反映出实际情况,具有一定的应用价值.
