“…Using the GEO (Geostationary Earth Orbit) microwave sounder as an example, more than 300 antenna/receiver units are needed to achieve 50 km resolution and 30 minutes image refresh rate [2]. Since the GEO sounder is foreseen to work in the millimeter wave band (53GHz, 183GHz, etc), it becomes challenging to develop such an interferometric system with so many receiving channels.…”

Synthetic aperture radiometers with a rotating thinned array can effectively reduce the number of antenna units required for the applications with very high spatial resolution, like GEO atmospheric sounding. The rotating array results in non-regular distributed visibility samples. A grid-based measurement approach is proposed in this paper to facilitate the image reconstruction and system performance evaluation, especially the radiometric sensitivity computation.

“…During the last decade, the technique has become increasingly used for remote sensing applications, see e.g. 4,5 . With this technique, signals from an array of receiver elements, distributed sparsely over a large aperture, are pair wise cross correlated to sample the complex-valued visibility function, i.e.…”

Millimeter and Sub-mm-wave imagers/sounders are considered for future meteorological geostationary satellite missions. A novel interferometric Geostationary Atmospheric Sounder (GAS) has been developed and a concept demonstrator is under construction. The concept is a response to the requirements of observations for nowcasting and short range forecasting in 2015-2025, as determined by EUMETSAT for post-MSG operational satellites observations. Prioritized parameters include vertical profiles of temperature and humidity with high temporal and horizontal resolution (15 min and 30 km) under all weather conditions. Frequency bands around 53GHz, 118GHz, 183GHz, 380GHz have the highest user priority and are all supported by GAS. The instrument relies on an innovative configuration of interferometer elements which enables the use of a sparse array and simplifies calibration.
