Abstract: 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.

Key words： radar moving target detection low-observable target refined processing feature extraction sparse representation target recognition
