Paper Abstract

The extended target that the size is larger that the diameter of the light beam can be tracked in the laser tracking radar designed on the basic of the method and the algorithm of the staring edge tracking. A moving aluminium plate is tracked by a coherent CO2 laser tracking radar facility with transmitter power 5W and the divergent angle of the transmitter light beam less than 0.18 mrad at a n approximate range of 1 km. The error signals of the azimuth and the elevation are generated from the quad detector. This successful experiment results indicates that the question that the traditional tracking method of quad detector is vain to the extended target has been overcome and testifies that our theory of the staring edge tracking is correct. This tracking method has many advantages. For example, is we choose the tracking position at the top of the target, then the ground target is not easy to lose. So it can avoid tracking the ground. On the other hand, the range of the laser radar using this method is longer than the range of the radar using the point tracking, because the target using narrow light beam illumination is taken as an extended Lambertian target.
