摘　　要：针对区域选择性精确干扰中干扰阵型的优化设计问题,对采用的分布式协同干扰体制、窄波束天线形式以及类脉冲的干扰信号样式进行了简单介绍,为保证精确干扰的同步要求需控制干扰信号的脉宽及发射时序。在此干扰体制及时、空域基础上,研究干扰阵型的孔径对区域精确干扰的影响,通过仿真不同孔径参数下考察区域和干扰区域内干扰合成效果的变化情况,分析干扰阵型孔径与干扰距离的比例关系对区域选择性干扰的影响及其规律,为分布式协同干扰的阵型结构优化设计提供指导。This paper introduces briefly the distributed collaborative jamming system,narrow-beam antenna type and pulse-like jamming signal types for optimal design of jamming array architecture in region-selective accurate jamming. In order to meet the synchronous demands of accurate jamming,the pulse width and launch time sequence need be controlled. On the basis of this jamming system,time and space domain,the influence of aperture of jamming array architecture on regional accurate jamming is studied. By simulating jamming combined effects of the considered region and the jamming region under different aperture parameters,the influences of the ratio of jamming array aperture to jamming distance on region-selective jamming and the influence rules are analyzed,which provides a guide for the array architecture optimization in the distributed collaborative jamming.
