Abstract: For fire control phased array radar, it is flexible to adjust the direction of the beam, so as to adjust the time resource of radar for tracking. Aiming at this characteristic, a kind of time resource management algorithm is proposed, which is used to enhance the maximum number of radar tracking targets. The tracking precision of the target is described with the probability density function, and the influence of ranging and velocity precision of the measurement on the tracking error is considered. The method of Markov’s decision is used to allocate the dwell time and revisit time interval for each target. The simulation results show that, compared with the traditional methods of resource management, the proposed method can increase the maximum number of the target and the radar can track with the same tracking accuracy.
