Paper Abstract

A multichannel scanning microwave spaceborne radiometer is described designed to sea ice monitoring, natural resources studied, ocean and atmosphere research and monitoring. The radiometer operates at the following wavebands: 0.4 cm, 0.8 cm, 1.35 cm, 2.0 cm and 5.5 cm. In the 0.4 cm waveband it receives radiation with only one polarization (either horizontal or vertical). In other wavebands it can receive vertically and horizontally polarized signals simultaneously. Precise polarization measurements are performed with the help of a scanning antenna system of a special design allowing to receive radiations at all the wavebands and polarization at exactly the same viewing angle with high polarization isolation. A mode when the forward and the backward survey lines are received simultaneously is provided. In addition, all the channels can be completely calibrated against both 'the absolute black body' and the open space. Digital signal processing is performed on board the satellite until absolute radiobrightness temperature values and images with rectified lines are obtained. Output data is presented in the form suitable for its reception and display at the available and widely used receiver stations.
