Abstract

For MW and MMW radar and radiometer measurements the influence of atmosphere like attenuation and path delay is more pronounced at higher frequencies. The sensors group of DLR Microwaves and Radar Institute operates the experimental radar System IoSiS (Imaging of satellites in space) at X band at the DLR ground station Weilheim in southern Germany. The radar images of the satellites in LEO (low earth orbit) are acquired in the ISAR mode (Inverse synthetic aperture radar) over a wide elevation angle of the steered Tx/Rx antenna. For the image processing and object focusing it is important to know the atmospheric attenuation and path delay variation over the wide synthetic aperture angle. The use of atmospheric models in order to retrieve the necessary parameters leads to some uncertainties since the models are mainly on a global scale and do not consider regional and seasonal conditions. Therefore the authors intend to refine an existing atmospheric model based on radiometric profiling measurements of the atmosphere for different weather conditions. The paper shows the measurement setup, mention briefly the Ulaby and ITU atmosphere models and show first experimental radiometer measurements of the atmospheric brightness temperature at four frequencies, namely at X, Ka, W and D band.
