Why does Synthetic Aperture Radar use different wavelengths? | SAR bands explained

Описание: The wavelength used in Synthetic Aperture Radar (SAR) determines what we can see in an image and the image resolution.

In this video, we’ll explore the different SAR bands, what kind of images they produce, and why the SAR band names are so peculiar.
