摘　　要：针对目前雷达干扰效能计算方法普遍较为复杂,指标参数获取困难,计算难度较大等问题,基于相控阵体制警戒雷达特点,提出了一种干扰效能快速计算方法,并对各指标参数进行了分析。利用速算图表、列线图等方式,实现雷达干扰效能快速计算,并绘制出雷达干扰效果图。研究结果表明,干扰效果主要与被掩护目标和干扰机对雷达张角、干扰机至雷达距离有关,通过保持干扰机、掩护目标和雷达的三点一线态势,并使干扰机尽可能抵近雷达实施干扰,可发挥最大雷达干扰效能。Aiming at the problem that the radar jamming effectiveness calculation method is complex,the index parameters are difficult to obtain,and the calculation is difficult,a fast calculation method of jamming effectiveness based on the characteristics of phased array warning radar is proposed.Analysis about each index parameter is carried out.Fast calculation charts and nomograms are used to quickly calculate radar jamming effectiveness and draw radar jamming renderings.The research results show that the jamming effect is mainly related to the angle between the covered target and the jammer to the radar,and the distance between the jammer and the radar.The maximum radar jamming effectiveness can be achieved by maintaining the three-point one-line situation of the jammer,cover target and radar,and making the jammer as close to the radar as possible to implement jamming.
