Target capacity for phased array radar

A method for analyzing the maximum target number of tracking for phased array radar is presented in this paper. At first, the optimum tracking parameters of phased array radar are studied. The optimization criterion is that the radar and computer resources consumed by each track are minimum. Then, the maximum number of the targets that a phased array radar operated in the optimum parameters can simultaneously track is presented. At last, the target capacity under different requirement of precision is analyzed when random target stream is assumed as Poisson stream. It is shown by the simulation tests that the limit tracking capacity of the phased array radar depends not only on the radar and computer resources but also on the accuracy required in the application and the kinetic feature of targets.
