SAR_specific_models

This project provides some SAR specific models with strong abilities to extract spatial features of single-polarization Synthetic Aperture Radar (SAR) amplitude images.

Environment

Pytorch 0.4.0 (also verified in Pytorch 1.4.0) Python 3.6

SAR-Specific Models

./model/resnet18_I_nwpu_tsx.pth [1]

The SAR image pre-trained model in Reference [1].

It can be transferred to other SAR classification or detection models with ResNet-18 backbone.

Transfer to Target Detection

Use MMDetection to transfer the pretrained model to SAR detection:

import torchvision.models as models
resnet18 = models.resnet18(pretrained=False)
pthfile = './model/resnet18_I_nwpu_tsx.pth'
resnet18.load_state_dict(torch.load(pthfile))

./model/resnet18_tsx_mstar_epoch7.pth [1]

The transferred model to MSTAR 10-class target recognition task in Reference [1], achieving an overall accuracy of 99.46%.

./model/alexnet_tsx.pth [2]

The SAR-image pre-trained model in Reference [2].

./model/alexnet_tsx_mstar_iter1920.pth [2]

The transferred model to MSTAR 10-class target recognition task in Reference [2], achieving an overall accuracy of 99.34%.
