摘要
全息凝视雷达是一种同时覆盖全空域、同时多功能的阵列雷达,该文首先明确全息凝视雷达定义,并概述全息凝视雷达特点、性能优势以及处理难点;然后,较为全面地介绍了全息凝视雷达的发展历程,归纳了当前的主要应用方向,并对中山大学在全息凝视雷达系统研究方面的进展情况进行了介绍,给出了实际场景下目标探测结果,展示了全息凝视雷达在低空目标监视等方面的应用潜力;接着较为全面地介绍了全息凝视雷达相关关键技术的研究进展,包括系统设计、收发波束控制、目标积累检测以及参数估计等方面;最后总结了全息凝视雷达的发展趋势。
Holographic staring radar is an array radar that continuously looks everywhere and performs multiple functions simultaneously instead of sequentially.First,this paper clarifies the definition of holographic staring radar and summarizes the features,performance advantages,and accompanying risks of holographic staring radar.Then,the research history and main application directions of holographic staring radar are reviewed.Next,the holographic staring radar series of Sun Yat-sen University in China is introduced.The target detection results of this holographic staring radar are given,showing the application potential of a holographic staring radar system in low-altitude target monitoring.Next,the research progress of related key technologies is examined,including system design,beam control,target detection,and parameter estimation.Finally,the development trends of holographic staring radar are discussed.
