Abstract

The invention discloses an intelligent radar marine target detection system and method based on a hybrid artificial bee colony algorithm. The system is formed by a radar, a database and an upper computer, which are connected in sequence. The radar is used for irradiating a detected sea area and storing radar sea clutter data to the database. The upper computer comprises a data preprocessing module, a robust forecast model modeling module, an intelligent optimization module, a target detection module, a model update module and a result display module. For complexity of marine target detection,the radar marine target detection system and method carry out reconstruction on the radar clutter data, carry out detection on the target data and introduce the hybrid artificial bee colony algorithm,and realize on-line detection and high intelligence.

Description

technical field [0001] The invention relates to the field of radar data processing, in particular to an intelligent radar sea target detection system and method based on a hybrid artificial bee colony algorithm. Background technique [0002] Sea clutter is radar backscatter echoes from the sea surface. In recent decades, with the in-depth understanding of sea clutter, Germany, Norway and other countries have successively tried to use radar to observe sea clutter to obtain radar wave images to invert wave information, so as to obtain real-time information about the state of the ocean, such as the Wave height, direction and period, etc., so as to further detect small targets at sea, which is of great significance to maritime activities. [0003] Maritime target detection technology plays an important role, and providing accurate target judgment is one of the important tasks of marine radar. The radar automatic detection system makes a judgment under a given detection thresho...
