巡航导弹对抗相控阵雷达突防能力分析是巡航导弹总体设计的重要内容,为研究巡航导弹不同设计参数对其突防能力指标的影响。提出了一种巡航导弹对抗相控阵雷达突防能力仿真分析的新方法,可根据巡航导弹对抗相控阵雷达的空间几何关系,提出采用探测区概念描述突防能力指标;运用物理光学法建立巡航导弹雷达散射特性的计算模型;在以上基础上,建立探测区突防能力指标计算模型;并给出探测区突防能力指标计算流程进行仿真。仿真结果表明,所建突防能力指标能够反映巡航导弹飞行高度、雷达散射截面积等性能参数对突防能力大小的影响,同时,通过仿真获得了巡航导弹不同巡航高度下,探测区突防能力指标的变化情况,验证了提出的方法有效性,并为提高巡航导弹突防能力途径提供借鉴。

The penetration effectiveness analysis of Cruise Missile Radar is important in design of Cruise Missile. In this paper, a new simulated method which can analyze the performance of penetration effectiveness was proposed to evaluate the influence of different parameters on the performance of penetration effectiveness. Firstly, based on geo- metric relationship of radar, the index describing the performance of penetration effectiveness using detection-zero concepts was proposed here. Secondly, based on the physical optical method, the mathematic model was used to ana- lyze the divergence parameters of Cruise Missile Radar. Then the mathematic model of index describing the perform- ance of penetration effectiveness in detection-zero was presented. Besides, the calculating process of index describing the performance of penetration effectiveness was given as well. As last, the simulated examples and the analyzed re- sults were proposed. The results show that the index describing the performance of penetration effectiveness can re- flect the influences of the Aviation altitude, area of RCS and so on. Meanwhile, the variation of index describing the performance of penetration effectiveness has been obtained in different aviation altitudes of CM through simulating. It is concluded that the method for penetration analysis proposed in this paper can fully meet the requirements of scheme demonstration.
