摘要
分布式相控阵雷达是一种多基地联合工作机制的新体制雷达,这种雷达主要作用于对空间大范围弱小目标进行精确检测和识别。文中简要介绍了分布式相控阵雷达的结构及工作流程,并根据分布式相控阵雷达对目标定位的要求及工作流程特点,提出联合旋转不变技术估计信号参数(ESPRIT)目标定位算法,该算法定位准确,且可以同时对多个目标定位。通过仿真,说明联合ESPRIT目标定位算法可以对目标进行定位,且定位准确。
Distributed phased-array radar is a new radar system with muhiple bases. Precise detection and identification of targets is main job of this radar system, especially when the target is weak and the space is very large. The structure and working process of distributed phased-array radar is introduced in this paper. According to the target localization requirements and working characteris- tics of distributed phased-array radar, joint-esprit localization algorithm is proposed. Accurate positioning and multi-target positio- ning are maximum advantages of this algorithm. Through the simulation, the joint-esprit target localization algorithm can locate the target, with accurate positioning.
