Abstract

CARABAS-II is a new airborne ultra-wideband and widebeam SAR which operates in the lower VHF band (20-90 MHz). Its design has been based on the experiences and insights gained from the earlier CARABAS system. The initial radar test flights were conducted during October-November 1996 which included a flight campaign as part of BALTASAR-96. The subsequent data analysis has resulted in a number of processed images with good image quality over a forested area in southern Sweden. The resolution of the imagery has been measured to 3×3 m². The present limitation before full performance can be achieved is due to uncompensated antenna characteristics
