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 invasive weed optimization 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 threshol...
