Based on the principle of BP neural network and the corresponding learning algorithm, and in view of the characteristics of the angle tracking system (ATS) on a certain type of fire-control radar, this paper uses the model and the learning method for fault diagnosis of the ATS.

This paper described the principle of Monopulse radar s angle tracking system simply,and introduced the methods of angle deception to monopulse radar.

Based on the analysis of the principle of angle tracking system of monopulse radars,the categories and efficiencies of blinking jamming are described.

After simply analyzing the deficiencies in countermeasures to the concealing scanning radar angular following system,a new method is presented which means scanning slowly in a smaller range after quickly scanning to get the precise sweep frequency.

This solution has the ability of angle tracking.

Based on the method of PLE Kalman Filter,the double-loop approach to AHM angle tracking is described in this paper.

Based on the operation characteristics of conical scan angle tracking system, the paper presents the spot jamming method against conical scan radar, discusses the instances when conical scan frequency error is zero and the error is general, and analyzes the jamming effect.
