Radar Resource Scheduling Algorithm Introducing Micro-Motion Targets Imaging with Sparse Aperture

To improve the battlefield perception and relieve the conflict of the radar resource distribution, a radar resource scheduling algorithm introducing micro-motion targets imaging with sparse aperture is proposed in this paper. Firstly, the resource scheduling optimization model was constructed and solved by heuristic algorithm. Then, the sensing matrix was constructed by using the tracking pulse aperture and the vacant aperture after scheduling other tasks. Finally, the micro-motion feature extraction and targets imaging could be achieved based on the Orthogonal Matching Pursuit (OMP) algorithm. Simulations demonstrate that the proposed algorithm can obtain the micro-motion target image as well as achieve higher resource utilization ratio.
