摘要 雷达探测环境复杂、探测对象特征多样,回波具有低可观测性,雷达探测性能难以满足实际需求,面临着复杂环境下微弱目标检测难题。本文论述了低可观测动目标的内涵、特征、雷达探测面临的挑战以及精细化处理的关键技术,结合雷达实测数据给出了工程应用的途径,并展望了对精细化处理的发展方向。 As the main equipment of target detection and surveillance, the radar plays an important role in the air and sea target monitoring, early warning detection and other public and defense security applications. Due to the complex detection environment and the variety of the targets, the echo has a low observability. It is dificult for the radar detection performance to meet the actual demand, and we face the weak target detection problem in a complex environment. In recent years, with the development of the radar system and the radar signal processing technology, the radar gains the ability to obtain fine target characteristics, and by extending the signal dimension, a new way is provided for the radar target detection and recognition. This paper reviews the connotation and the characteristics of the low observable moving target, the challenge of the radar detection and the key technology of fine processing, focusing on the engineering applications based on the measured data of the radar. Finally, the development direction of fine processing is discussed.
