This paper introduces the characteristics of Windows operating system and the monitoring control system of the monopulse tracking receiving equipment for spatial active target, and points out the contradiction of them.

The stability and high precision of tracking servo system can not be reached at the same time by using traditional monopulse tracking method, so a computer-aided tracking technology is adopted in tracking servo system for this problem.

In the monopulse tracking system,traditional phase calibration relies on the calibration tower.

There are two tracking ways for "communication on the move"(COTM) at present vehicle which are inertial Navigation direction and monopulse tracking.

A design of tracking receiver of radar with high dynamic range is offered in this paper.

But the antenna polarization plane adjustment would cause the tracking receiver phase to change and lead to the decline of antenna tracking performance.

With the change of geographical location, the polarization of sum/difference channels is different, the phase difference ΔΦ between sum and difference signals will change and the cross-coupled feature of tracking receiver will change, so the antenna can not keep tracking automatically.

The paper provides a design and engineer realization of track receiver in 2cm multipolarization target characteristic instrumentation radar,and analyses several factors about to affecting track precision.
