Investigation of ground moving target indication techniques for a multi-channel synthetic aperture radar [PDF]

, 2020
Synthetic Aperture Radar (SAR) is an imaging technique that creates two dimensional images of the scattering objects in the illuminated ground scene. The objects in the illuminated ground scene may be truly stationary, e.g. buildings etc.

Acceleration Independent Along-Track Velocity Estimation of Moving Targets [PDF]

, 2008
In the paper a method for along-track velocity estimation of moving targets is presented. This method exploits the along-track interferometric (ATI) phase ramp of a range compressed moving target signal between two or more receiving channels.
