Abstract: In order to improve the survival ability of radar, and keep the radar tracking ability at the same time, this paper proposes a target tracking technology of fire control radar based on adaptive pulse interval. An improved signal model and normal signal is proposed. Extended Kalman filtering algorithm for Constant Acceleration(CA) target is expounded. The principle of choosing pulse interval based on adaptive technique is introduced and interception possibility is analyzed. Simulation results show that this technology can achieve a high accuracy of target tracking and prolong signal intercept time, and reduce the interception probability of reconnaissance system for fire control radar.
