摘要
为了提高反辐射导引头角度搜索的速度,文中提出了一种基于数字波束形成的快速测向技术。该技术基于折半查找的思想,将角度搜索问题转换为利用不同宽度的数字波束进行空间目标角度的折半查找问题。研究了该方法的基本原理,分析了其搜索速度和运算量。仿真结果显示,该方法在保证应有的测角精度与角度分辨力的条件下,解决了传统数字波束形成时侦测时间较长,且效率低的问题。
A fast direction finding technology based of anti-radiation seekers. The problem of angle searching digital beam with different widths. The basic principles, studied. The simulation results show that the searing time while keeping the same angle measurement accuracy and on digital beam forming is p is converted into the binary angles searching in space using the speed and the amount of computation of this method are casting and efficiency are improved by the proposed method resolution.
