Adaptive Power Allocation Algorithm For Multiple Target Tracking

Reasonable power allocation algorithm can improve the radar’s efficiency and ability of radio frequency stealth. Based on interacting multiple model probabilistic data association algorithm and covariance control method, we propose a power allocation algorithm for radar tracking based on target features, and radar’s radiated power is allocated adaptively according to the target state. Firstly, each desired covariance is set for each tracking target, and the radiated power is designed according to forecasting the target distance and the size of the radar cross section. On the premise of meeting tracking accuracy, we design a power allocation algorithm. Comparing the proposed algorithm with the traditional power control algorithm, not only the tracking algorithm has good tracking accuracy, but also it can control radiated power reasonably and reduce the consumption of radar radiated energy, improve the radar’s ability of radio frequency stealth, the radar resources can be allocated reasonably and increase number of targets which can be tracked.
