Motion measurement impact on synthetic aperture radar (SAR) geolocation
Radar Sensor Technology XXV, 2021 Often a crucial exploitation of a Synthetic Aperture Radar (SAR) image requires accurate and precise knowledge of its geolocation, or at least the geolocation of a feature of interest in the image. However, SAR, like all radar modes of operation, makes its measurements relative to its own location or position.
