Microwave radiometer

A ground-based microwave radiometer system with dual-polarized receivers (vertical & horizontal polarizations) operating at 36.5 and 18.7 GHz for satellite cal/val activities. See also the optional modules in the annex 1. The system should have a modular design allowing measurement with and without a positioner using flexible receiver module (frequency) combinations. The bidder may select a positioner system capable of azimuth/elevation turning and design the radiometer system to fit the chosen positioner. Including the positioner itself in the tender is optional, but a significant part of the quality comparison. The system should enable both autonomous and campaign-type operation via a remotely or locally operated connection. The system should enable automated storage and preprocessing of observations and operation of azimuth/elevation positioner according to predefined scheduler. The design must enable continuous operation using mains power. The radiometer must be operable in Arctic environmental conditions, providing system stability according to specified requirements.
