航迹规划中雷达探测空间的生成

从飞机突防习行任务规划出发，综合考虑地球曲率、陆地（或海洋）的反射和杂波干扰、大气折射和吸收损耗等因素的影响，采用临界散射截面法生成了对空警戒雷达在不同地貌、发现概率下，对不同雷达散射截面的目标的探测空间。计算并分析了飞行高度、目标雷达散射截面、发现概率和地貌等因素对雷达探测空间的影响，以便选择低探测概率的飞行走廓，这对制定和实施安全突防飞行策略有实际意义。

Generation of radar detection space in the flight vehicle route planning

With the view to aircraft penetration flight mission planning,detection space of early warning radar which detects different radar cross section(RCS)of targets at different physiognomy and in different detection probability is generated by critical RCS method,with the following factors being taken into account:curvature of the earth,reflection and clutter interference of land or sea,atmospheric refraction,atmospheric loss,and so on. The influence of flight height,target RCS,detection probability and physiognomy on the radar detection space is calculated and analyzed in order to select a low detection probability flight corridor. It is of practical significance to draw up and implement safe penetration flight strategy.
