Adaptive dwell scheduling for simultaneous multi-beam radar system based on array element selection with different polarization characteristics

Abstract

Adaptive dwell scheduling is a key for simultaneous multi-beam radar system to give full play to its tactical performance. The dwell scheduling for such radar system based on the selection of array elements with different polarization characteristics is first investigated in this manuscript. The optimal dwell scheduling model whose goal is to achieve the maximal scheduling gain for the system is established under the time, array element, frequency and electromagnetic compatibility constraints of the system. The solution of this optimization problem results in our proposed dwell scheduling algorithm, where the dwell tasks are selected to be analyzed sequentially according to synthetic priority at each scheduling analysis time point, and the element sets are chosen for dwell tasks under all kinds of constraints to realize the simultaneous execution of multiple tasks. Simulation results demonstrate that the proposed algorithm can realize real-time dwell scheduling and achieve better scheduling performance for the multi-beam radar system compared with existing algorithm.
