运动平台轨迹计算方法研究

Study on Trajectory Algorithm of Motion Platform

摘要: 飞行试验过程中，采用多种设备进行被测目标的全程跟踪，由于受设备作用距离，通讯带宽，飞机姿态引起的遮挡等原因，测量雷达、光电经纬仪和无线通讯设备接收到的飞行轨迹信息含有大量异常信息且不连续，为了获得目标完整的可靠的全局轨迹，根据各设备的特点，结合运动动平台的位置和姿态信息，设计了一种轨迹生成算法，可以稳定、连续的获得跟踪目标全局轨迹，满足飞行测试与指挥的需要。

Abstract: The tracked plane target is tested by a variety of devices in whole flight test. The plane trajectory signals which are received through moving base radar, moving base photo-electric theodolite and wireless communication device, are discontinuous and contaminated. The discontinuous data and outlines are caused by the devices coverage, communication bandwidth limitation as well as signal blockage. In order to get the whole trajectory, a sort of common track synthesis algorithm is de-signed according to the characteristics of the device, the moving platform position and attitude. The steady continuous trajectory can be get, and the trajectory data are satisfied for the need of flight control and test.
