Radar remote sensing technology has revolutionised the way we perceive and understand our world. But similar to other remote sensing sensors a radar system also has its unique set of challenges when it comes to creating accurate images. <\/p>\n\n\n\n

SAR data can be a bit distorted because of how the sensor works, especially in rough terrains with varying topography. Radiometric terrain correction is a method to fix these distortions and make sure the data matches up with other maps and can be used for things like GIS. In this post, we will explore the peculiar distortions that radar imagery can exhibit due to its side-looking viewing geometry and its nature as a distance-measuring device.<\/p>\n\n\n\n

In mountainous areas the effects of geometric distortions are more marked. The image shows mountain valleys between the provinces of La Rioja and Soria (Spain)<\/figcaption><\/figure>\n\n\n\n
