Collaborative Route Planning and Dwell Time Allocation for Multi-target Tracking in UAV Radar System

Abstract

AbstractIn order to fully exploit the potential of the radar system under the constraint of limited transmit resources, extensive researches have been conducted in recent years. However, most of these strategies are designed for multi-target tracking (MTT) by ground-based radars, which are stationary in position. While considering the MTT scenario by airborne radar, the situation will become much more complicated, because more degrees of freedom are introduced. In view of it, this paper proposes a collaborative route planning and dwell time allocation (CRP-DWA) strategy for MTT in unmanned aerial vehicle (UAV) radar systems, which aims to improve the tracking accuracy of multi-target by jointly coordinating the UAV route planning and dwell time allocation. An efficient and fast four-stage solution methodology is put forward to tackle the resulting optimization problem. Finally, simulation results demonstrate the effectiveness and superiority of the proposed CRP-DWA strategy.KeywordsCollaborative route planning and dwell time allocation (CRP-DWA)Multi-target tracking (MTT)Unmanned aerial vehicle (UAV)
