ESA Echoes in Space - History: The SAR principle

preview_player
Показать описание
Prof. Iain Woodhouse explains the principle behind Synthetic Aperture Radar (SAR) antennas.

Echoes in Space is the first Massive Open Online Course on Radar Remote Sensing, funded by the European Space Agency (ESA).

Echoes from space will take you on a journey through the exciting world of Radar Remote Sensing. Learn the basics that will help you to understand where this technology is coming from, how the images are acquired and which manifold applications already use Radar Remote Sensing to help protect our planet.

I have a doubt...
While moving down in the azimuth direction, When the satellite is far away, the incidence angle would be different. And when the satellite is directly above the target and when the satellite moves further away the incidence angle keeps on changing. But how in the end, the acquired satellite image is of same incidence angle throughout the image? (like the satellite image we download from Copernicus Open Access Hub)
