Abstract

Abstract: The phased array radar can simultaneously perform multiple tasks, such as searching, tracking, recognition, and imaging. To improve the battlefield perception and relieve conflict of resource distribution of the radar, an optimal radar resource scheduling algorithm is proposed based on integrated tracking and imaging of micro-motion targets in this paper. In the algorithm, the radar resource optimization scheduling model is established and the heuristic algorithm is used to solve it. The perceptual matrix is dynamically constructed by using the tracking pulse and the remaining idle time resources of the scheduling. And the feature extraction and imaging of micro-motion target is realized by using the Orthogonal Matching Pursuit (OMP) algorithm. Simulations demonstrate that the proposed algorithm can obtain the image of the micro-motion target in the case of the sparse aperture and have good robustness, and can achieve higher resource utilization ratio of the radar system.
