The Danish C Band Sar. Calibration Accuracy And Stability

Abstract

At the Electromagnetics Institute, Technical University of Denmark, an airborne C-band SAR has been designed and constructed. The first test flights has been carried out, and imagery with a verified resolution of 2.0 by 2.1 m have been acquired from a flight altitude of 41,000 R. and a slant range of 25 km. The calibration and the stability of the radar have been of great concern during the design and development phase, and the present paper will highlight these aspects through a discussion of design considerations and stability measurements. Other aspects are covered in [U, [2], 131, and [41.
