太赫兹雷达宽带STAP算法研究

Study of terahertz radar wide band STAP algorithm

摘要:

太赫兹雷达可以对地面进行高帧率高分辨力成像，是太赫兹技术领域研究热点。针对太赫兹雷达宽带高分辨成像与地面动目标检测一体化实现需求，提出了一种基于宽带空时自适应处理(STAP)的地面运动目标检测算法，首次在机载太赫兹雷达上实现了同时对地高分辨雷达成像监视和多通道地面动目标指示(GMTI)检测。机载太赫兹雷达实测数据验证了算法的有效性。

Abstract:

Terahertz radar bears the advantages of high resolution and high frame rate. It is one of the current research hotspots in the field of terahertz. Aiming at the demand for real-time ground imaging and moving target tracking, a Ground Moving Target Indication(GMTI) processing algorithm based on wide band Space-Time Adaptive Processing(STAP) is proposed. The radar imaging and Multi-channel GMTI are achieved simultaneously on the airborne terahertz radar for the first time. The effectiveness of the algorithm is verified by the experimental data of the airborne terahertz radar.
