Image Validation Test using LICEF-1 Receivers

Abstract

An image validation test using two LICEF-1 receivers and a DICOS-3A correlator provided by ESA-ESTEC and its contractors has been performed. The receivers have been integrated on the DLR aperture synthesis positioning frame, which was controlled by a separate control computer running a corresponding MATLAB code. A total of 27 individual measurements of different scenes and different measurement setups have been carried out. Most of the data records have been made using 1.2s of integration time and a 4m´2m scan area of a T configuration. Hence the corresponding synthesized square aperture size was 2m´2m with a corresponding maximum spatial resolution of about 3.6°. The measured scenes can be roughly divided into three types: the imaging of artificial point sources and the imaging of two natural brightness temperature distributions. Two locations for the synthesis instrument have been chosen, one on ground and the other one on the roof of a building.
