Study on the Optimal and Adaptive Search of Multifunction Phased Array Radar

The beam agility and controllability of system parameters provide phased array radar systems the capability of concurrent multifunction and the potential of high adaptability. It is very important to allocate the constrained radar resources to the radar tasks adoptively according to the dynamic change of the environment and the operational requirements in order to optimize the overall performance of the systems. The optimal model of the allocation of the radar resource is presented based on the quantified radar load in this paper. The parameter optimization of the search function of a Pulse-Doppler phased array radar is investigated, the method to design optimal search in an adaptive way is formulated and the impact of the model parameters on search performance is analyzed through simulations.
