摘要:
载有成像雷达的旋翼无人机具有成本低廉、对起降条件要求低、飞行姿态灵活多样等优点,可以在热点区域进行普查、详查或长时间悬停凝视等多模式成像监测,现已成为海上船只目标监测识别的重要手段。本文分别从旋翼无人机雷达硬件系统、无人机载雷达动目标成像、船只目标类型识别和目标三维结构特征提取等四方面开展国内外研究进展综述。总结分析发现当前利用旋翼无人机雷达进行船只目标成像和类型识别,尚存在运动船只成像散焦、三维结构重建难度大、类型识别精度低等问题,迫切需要推动相关技术的发展。

Abstract:
Unmanned rotorcraft-borne imaging radar has the advantages of low cost, low requirements regarding takeoff and landing conditions, and a flexible flight attitude. This radar can be used for general surveys, detailed investigations, or long-term hovering gaze monitoring in hot spot areas. Unmanned rotorcraft-borne imaging radar is becoming increasingly important in marine reconnaissance and surveillance. In this paper, we review research progress on the rotor UAV radar hardware system, moving target imaging by UAV radar, ship-target type recognition, and the extraction of target 3D structure features. Our findings indicate that problem areas with this radar include defocusing when imaging moving ships, difficulty in the reconstruction of 3D structures, and low accuracy with respect to type recognition, all of which must be addressed to promote the development of related technologies.
Key words:  unmanned rotorcraft  UAV radar  ship target  three-dimensional imaging  type recognition
