Abstract

The invention discloses an intelligent radar maritime target detection system and method based on an improved artificial bee colony algorithm. The system is composed of a radar, a database and a hostcomputer which are sequentially connected. The radar irradiates a detected sea area and stores radar sea clutter data to the database. The host computer includes a data preprocessing module, a robustforecasting model modeling module, an intelligent optimization module, a target detection module, a model updating module, and a result display module. According to the invention, as for the complex characteristics of maritime target detection, the radar clutter data are reconstructed, the target data are detected, and the improved artificial bee colony algorithm is introduced, so as to provide the highly intelligent radar maritime target detection system and method capable of realizing online detection.

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 an improved 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 thre...
