Abstract: Aims at the cooperative detection technology of airborne phased array radar for fighter formations and in order to optimize the resource allocation of phased array radar, a task time allocation model is established for radar coordination in this paper. Firstly, the tracking ability and search ability of airborne phased array radar are quantified according to the Cramercroft and signal detection theory. Then, the phased array radar management optimization function with the shortest working time under short-term task conditions is established. The simulation results show that the short-term task assignment model can improve the performance of the radar.
