针对在主要作战方向上工作的光电侦察系统，提出一种低成本的光电搜索设备获取目标数据的方法。采用光电探测器持续以固定角速度周转扫描的方法，多次连续捕获目标，不断迭代刷新目标方位和时间数据，完成对来袭目标相对侦察设备的角位置和水平距离的解算。推导出观测目标数据的数学模型，通过设计仿真软件，实验程序可在目标进入侦察设备观测边界范围后解算出其方位角，得出目标在不同时间的方位角、俯仰角和水平距离等信息，能够满足在侦察距离不小于20 km的状态下实现对速度不大于500 m/s、高度不超过5 km的目标进行跟踪，完成了对光电侦察设备的仿真验证，为后续火控计算提供了可靠数据。

Aiming at the photoelectric reconnaissance system working in the main operational direction, a method for obtaining the target data with low-cost photoelectric search equipment was proposed. The method of continuously scanning at a fixed angular velocity was utilized for the photodetector to capture the target at several times and to iterate and update the target azimuth and time data continuously, thus complete the calculation of the angular position and horizontal distance of the incoming target relative to the reconnaissance device.Furthermore,we deduced the mathematical model of target data.Through designing the simulation software, the experimental procedure can calculate the azimuth angle of target after the target enters into the observation boundary of reconnaissance equipment, and the information of target at different time azimuths, pitch angles and horizontal distances can be obtained .It can meet the tracking requirements for targets with a speed of no more than 500 m/s and a height of no more than 5 km in a state where the reconnaissance distance is not less than 20 km, realizes the simulation verification of the optical reconnaissance equipment,and provides reliable data for subsequent fire control calculations.
