摘要
针对雷达电磁环境模拟系统遮盖性干扰的模拟仿真,分别建立干信比和压制系数数学模型,然后利用功率准则分析评估遮盖性干扰效果.仿真分析表明:有效干扰区域由干扰方位、最小干扰距离和天线方向图形状3个要素决定;最小干扰距离受有效干扰功率、干扰机与雷达的距离和雷达发射功率影响较大.
Aimed at the simulation of blanket jamming of the radar electromagnetic environment simulation system, this paper establishes the models of interference-to-signal ratio and jamming blanket factor respectively, and then, analyzes and evaluates the effect of blanket jamming using power criterion. Simulation analysis shows that the effective interference area depends on the three key elements, such as interference orientation, minimum jamming range and the shape of antenna radiation pattern, and the minimum jamming range is mainly determined by effective interference power, distance between the jammer and the radar and the transmitted power of the radar.
