摘　　要：航空光电侦察平台具有稳定跟踪功能,能够隔离载机姿态运动和其他干扰力矩所造成的摄像机光轴在惯性空间内的抖动,以保证获取清晰的图像。光电侦察平台能够输出摄像机的方位角、高低角,并能通过激光测距机测量目标和载机的距离,这给目标测速的实现提供了可能。基于航空光电侦察平台,结合载机自身的导航数据,提出一种新的目标测速算法。介绍测速系统结构和坐标系定义,推导动目标测速算法,并建立测速误差模型。仿真结果表明,该算法能够有效测量目标速度,具有较强的实用性。Aerial electro-optical platform has the stable tracking function, which can insulate the jitter of the camera optic axis caused by the aircraft attitude change and other disturbance torques to obtain the clear images. The electro-optical platform can output azimuth angle and elevation angle of camera, and the distance between target and aircraft can be measured by the laser range finder, which offer the possibility to realize the velocity measurement of moving target. Based on the electro-optical platform, with the navigation data of the aircraft, a novel target velocity measurement algorithm is proposed. Firstly, the system structure of velocity measurement is described and the coordinate systems are defined. Then, the velocity measurement algorithm for moving target is deduced and the velocity measurement error model is established. The simulation result shows that the algorithm can effectively measure the target velocity and has great practicality.
