Joint Beam-Time Allocation of Phased Array Radar Based on Variable False Alarm Rate Detection

Conventional searching methods with only one constant false alarm rate can no longer provide effective detection performance for different remote targets associated with distinct signal-to-noise ratios in radar systems. To overcome this problem, this paper presents a dynamic joint beam and time resource allocation strategy based on variable false alarm rate detection framework for phased array radar for remote target searching. Specifically, a multi-stage searching framework of the phased array radar is first developed, where the false alarm probability for detection increases adaptively with the stage evolving. Then, a constrained allocation model of the beam and time is formulated. Simulation results demonstrate the effectiveness and superiority of the proposed algorithm against some counterparts in terms of detection performance and efficiency of resource utilization.
