How do you handle the issue of inconsistent channels in different RS data? 你是怎么处理不同RS数据通道不一致的问题的？

Thank you for your work. As we all know, different RS data have different numbers of channels. For example, optical images have three RGB channels, SAR images have one channel, and hyperspectral images have even more channels. May I ask if you used separate visual encoders for each and aligned their features, or did you convert all the data into three-channel data to share the same encoder?
感谢您的工作，众所周知，不同的RS数据有不同的通道数，例如光学图像有RGB三通道，SAR图像有一个通道，高光谱图像有更多通道数，请问您是用了各自的视觉编码器，并将他们的特征对齐吗？还是将这些数据都转为三通道数据共享同一个编码器呢？
