摘要
根据数字阵列雷达预警搜索工作模式,结合在正弦空间中天线方向图不随扫描角变化的特点,提出了一种适用于数字阵列雷达搜索空域覆盖的波位设计方法。该方法利用三角变化和二次方程解算实现了搜索区域内波位指向的快速计算,与传统波位编排方法相比,在完成覆盖搜索空域的同时有效减少了波位数量。
According to the early-warning search mode of the digital array radar,combining the characteristics that the antenna pattern does not change with the scanning angle in sinusoidal space,a beam arrangement method is proposed for airspace coverage search of the digital array radar,through which the rapid calculation of the beam pointing is achieved in the search area with the conversion of trigonometric function and quadratic equation solution.Compared with conventional beam arrangement methods,it can effectively reduce the number of beams while completing airspace coverage search.
