“…Avoid the problem of that it is difficult to find the values of four parameters to satisfy the equation (7) and (8) in direction of the elevation and azimuth at same time. If the tracked target is a smooth and evasive angle, then it is impossible to find the solution associated with equation (7) and (8) using the previous methods.…”

“…The question of four parameters in equation (5) and (6) is changed to how to find the values of the two parameters in equation (7) and (8). It is clear that the approach usingthe two parameters that has been applied to the coherent CO2 laser tracking radar system is more easy to seek the values of kA and kE than the method offour parameters ofk1 ( i 1, 2, 3, 4).…”

The extended target that the size is more large than 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 (30 cm X 30 cm) is tracked by a coherent CO2 laser tracking Radar facility with transmitter power 5 W and the divergent angle of the transmitter light bean less than 0. 1 8 mrad at an approximate range of 1 km. The errOr signals of the azimuth and the elevation are generated from the quad detector. This successful experiment result 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, if 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 OEiki hand, the range of the laser radar using thismethod 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.
