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 designed 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.
