单脉冲雷达扫描方式分析与仿真

摘要

针状波束单脉冲雷达作为跟踪雷达对目标进行跟踪时,首先需要在指定空域完成目标的搜索捕获,而后再进入跟踪状态.雷达扫描方式的不同对目标的捕获性能特别是捕获概率的影响也较大.基于已有的研究对几种常用的扫描方式进行了分析与仿真,比较了各自的优劣情况,给出一种最优化思想及实现方法.仿真结果表明,螺旋形扫描性能最好,但是对系统性能要求较高,栅形扫描对系统要求较低,但扫描性能最差,其他扫描方式性能居于上述扫描方式之间.%As a tracking radar system, the monopluse radar with acerate beam needs to search and acquire targets first in the assigned space. The capability of acquiring targets, especially the acquisition probability, is largely influenced by the scanning mode. So this paper analyzes the regular used modes based on the existing study, compares their advantages and disadvantages, and indicates an optimization method and it.s realization.The simulation result shows that the screw scanning mode has the best capability but needs more systemic requirements, the grid scanning mode is contrary to the screw and the others just between them.
