摘要
Abstract
The shadows of moving targets in video synthetic aperture radar(Video SAR)images can reflect their real positions,and an improved YOLOv5 model is proposed to address the problems of low detection probability and false alarms in the current method of detecting shadows using deep learning to detect moving targets.The algorithm is based on the YOLOv5 framework.On the one hand,it adds a small target detection layer,introduces a three-dimensional attention mechanism that takes into account the channel and space,and adjusts the loss function calculation method to the intersection over union based on minimum point distance method to improve the network's ability to detect shadows of moving targets;on the other hand,it adds the road extraction as a decision condition to reduce the interference of the shadows of static objects outside the road in detecting the shadows of moving targets.After experimental verification,the algorithm improves the average accuracy by 7.12%compared with YOLOv5,which meets the requirements of moving target detection.关键词
