基于增强局部特征提取的SAR密集目标检测
SAR Intensive Target Detection Based on Enhanced Local Feature Extraction
摘要
Abstract
Aiming at the low accuracy of SAR image detection in dense areas,an improved algorithm to enhance local feature extraction ability is proposed.The CNeB module is used to enhance the feature extraction of small targets by reducing the spatial dimension and expanding the receptive field of the model.BRA mechanism is introduced to enhance the model's ability to understand the target context information.The loss function WIoU replaces the old CIoU and suppresses the harmful gradients produced by low quality images through intelligent weight adjustment mechanism.Verified on HRSID dataset,mAP increases from 92%to 94.4%,recall rate and accuracy are improved by 4%and 1.1%,respectively,proving that the improved algorithm has significant advantages in intensive target detection.关键词
