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%.

sar_specific_models's Issues

I couldn't find tsx_dataset file, which is used to storage tarrasar-X imgs

After reading the paper, I know that this is the annotation set marked by your team. Have you published this data set and where can I download this data set, so that I can train and test your model

关于权重文件

是只有./model/resnet18_I_nwpu_tsx.pth这个模型可以用于mmdetection的目标检测吗？通过joint训练出来的模型可以用嘛？

I cannot find " train_or_test" file, which is used tp train resnet-18.

After reading the paper "Classification of large-scale high-resolution SAR image with deep transfer learning", i am interested in transfer learning, but i cannot find "train_or_test" file

Hello, author. I wanted to inquire about the generation process for 'spexy_data_3'

Hello, author. Thank you very much for providing the code; it has been a great help.
However, I might have overlooked something, as I couldn't find any information in the code regarding
how 'spexy_data_3' is generated.
Therefore, I would like to inquire about the process of generating 'spexy_data_3.' Thank you!
