Performance Evaluation of Fire-Control Radar with Adaptive Pulse Interval

In order to solve the problem of antagonizing anti-radiation weapon, a tracking method based on adaptive pulse interval is proposed for fire-control radar. First, an improved signal model for fire control radar is proposed after the monopulse signal expression is given. Then, the principle of adaptively choosing pulse interval based on tracking precision is introduced. The algorithm of using Extended Kalman Filtering for Constant Acceleration (CA) moving target to calculate tracking precision is expounded afterward. Relevant indexes are simulated, and results show the method proposed in this paper can achieve a high precision of target tracking and antagonize anti-radiation weapon effectively by reducing the interception possibility.
