  • Abstract
    The application of the clutter-lock technique in case of fast and significant instabilities of the antenna orientation leads to strong geometric distortions in SAR images. In the paper we propose a radiometric correction approach which could be used with SAR processing algorithms without clutter-lock. The technique has been tested by using a Ku-band airborne SAR system, installed on a light-weight aircraft.
