摘　　要：三坐标相控阵雷达探测的空中目标为无人机、直升机等,各型目标的飞行一般都有其典型高度,不会超过某个固定高度。结合某雷达系统的总体方案设计,根据雷达在俯仰维内探测目标的空域分布典型特点,提出一种探测空域和波形精细化设计方法,在保证雷达正常搜索范围的前提下,可有效地缩短雷达的对空搜索时间,提高雷达搜索数据率。该方法同样可用于对地面目标的探测波形设计中。Three-coordinate phased array radar detects aerial targets such as unmanned aerial vehicles and helicopters.The flight of each type of target generally has its typical height,and will not exceed a fixed height.Based on the general scheme design of radar system and the typical characteristics of radar target distribution in pitch dimension,a refined design method for detecting airspace and waveform is presented,which may effectively shorten the radar searching time and improve the radar searching.This method can also be used in the design of detection waveforms for ground targets.
