Microwave radiometer MTVZA-OK of spacecraft "sich-1M"

The microwave radiometer MTVZA-OK is based on the technology of combining in space and time multifrequency and polarisation measurements. MTVZA-OK combines both the optical and microwave systems deployed on a single scanning platform. Field of view is common for optical and microwave imaging and sounding channels. The scanning platform rotates continuously about an axis parallel to the local spacecraft. The sampling rate is 19/spl times/19 km for all microwave channels. To provide required sensitivity the size of imagery pixel differs depending on channel frequency. Both atmospheric temperature profile and atmospheric humidity profile, sea surface temperature and near-surface wind speed, ocean color and process of active ocean layer will be observed concurrently, enabling flow visualization and upwelling area to be observed as well as estimates of ocean-atmosphere interaction.
