摘要

多功能相控阵雷达可以灵活地对不同目标进行交替观测,而雷达资源的合理分配是优化雷达整体性能的基础。文中提出了一种基于稀疏孔径ISAR成像的雷达资源自适应调度算法。多目标成像时,在对目标特征进行认知的基础上,根据反馈信息合理分配雷达时间资源对目标交替观测,再采用基于压缩感知的稀疏孔径成像方法对不同目标进行成像,从而在保证达到期望成像质量的基础上,显著提高雷达时间资源的利用率。仿真实验验证了该算法的可行性。

Abstract

Multifunction phased array radar (MFPAR) can alternately observing targets, therefore it's required to allocate the limited resources of radar to optimize the overall performance of MFPAR. An adaptive scheduling algorithm based on sparse aperture ISAR imaging was proposed in this paper. In the proposed algorithm, the target characteristics in multi-target imaging were cognized first. Then the time energy resources of radar were allocated according to the feedback information. Finally, the ISAR image of each target was formed with the gapped data by using the compressed sensing (CS) theory. It can significantly improve radar resource utilization while achieving desired image quality. The effectiveness of the proposed method was demonstrated by simulation experiments.

Key words： phased array radar; adaptive scheduling; sparse aperture imaging; compressed sensing
