摘　　要：在稳定的惯性空间中,利用被动目标测量装置测得的目标方位角和俯仰角,求取载机到地面目标的距离,实现对丘陵目标和山地目标的精确定位,并完成了数字仿真和精度计算。该方法的计算模型简单,占有的计算时间和存贮容量都比较少。通过仿真计算和精度分析说明,该方法适用的载机飞行高度速度范围广,具有良好的推广应用价值。There are various sorts of methods for locating the ground targets from the aircraft. In this paper, the range to a target on a hilly land is calculated out by using its azimuth and elevation measured by passive detection devices onboard the aircraft, and thus the precise location of the target can be obtained. The digital simulation and the accuracy analysis are also implemented. The model of the method is simple, and the required executing time and memory capacity are less. The results of the simulation and accuracy analysis show that the method is applicable to a wide scope of flight altitude and flight velocity.
