Anglefree
Anglefree refers to a visual distortion effect that can occur in certain digital imaging processes, particularly in the context of synthetic aperture radar (SAR) or other remote sensing technologies. It describes a situation where the apparent angle of an object in an image is not consistent with its actual geometric angle relative to the sensor. This can lead to misinterpretations of the scene being depicted.
The phenomenon arises from how data is collected and processed. In SAR, for instance, the sensor transmits
This effect can be particularly noticeable in areas with steep terrain, complex structures, or when observing
