摘要/Abstract

摘要： 相控阵雷达可以同时担负搜索、跟踪、识别与成像等多种雷达任务。为了提高雷达对战场环境的感知能力并减轻雷达资源分配的冲突，提出一种微动目标跟踪成像一体化的雷达资源优化调度算法。该算法建立了包含微动目标成像任务的雷达优化调度模型并利用启发式算法求解，利用跟踪脉冲与调度剩余的空闲时间资源，动态地构造感知矩阵并采用正交匹配追踪（OMP）算法对微动目标进行特征提取并成像。仿真结果表明：该算法可以实现稀疏孔径条件下的微动目标成像，并具有良好的鲁棒性，同时进一步提高了雷达系统的资源利用率。

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.
