Research on Ship Identification Technology Based on Radar / AIS Composite Features

Aiming at the monitoring and identification requirements of the imaginary enemy naval fleet, the ship identification technology based on radar / AIS composite features is proposed. Firstly, based on the detection information of space-based radar, the target features, such as motion trajectory and High Resolution Range Profile (HRRP), are extracted. Then AIS information is introduced to assist the identification of military and civilian targets. Finally, multi-source information fusion technology is used to realize the comprehensive identification of sea surface ships and the key annotation of military targets, so as to provide guidance information for subsequent multi-satellite cooperative continuous tracking and accurate identification of optical / SAR imaging. The verification based on the measured data show that the proposed technology can improve the tracking and recognition efficiency of space-based radar for military ship targets, and provide technical support for the development of space-based sea surface surveillance and recognition system.
