The development of a sensitive filter radiometer for the Atmospheric Radiation Measurement (ARM) Program has been reported by Platt et al. (1994, 1995). The aim was to develop a reliable and fast instrument that could be used alongside a lidar to obtain near realtime optical properties of clouds, particularly high ice clouds, as they drifted over an ARM Cloud and Radiation Testbed (CART) site a...

The geostationary orbit microwave multi-channel radiometer has the advantages of high real-time performance and large coverage, which plays an important role in typhoon, strong precipitation detection, medium-to-short-term meteorological/oceanic forecasting. However, due to difficulty engineering development payload, its application on-orbit not yet been achieved at present. To satisfy requirem...

Abstract This paper presents measurements using a dual-polarised radiometer operating at 93 GHz to detect ice or water on asphalt in laboratory conditions. The brightness temperatures of both H and V polarizations were measured for dry surface, liquid water, observation angles 50° 56°. results presented this demonstrate that the studied road conditions can be identified by radiometer. are compa...

Radio frequency interference (RFI) is a risk for microwave radiometers due to their requirement of very high sensitivity. The Soil Moisture Active Passive (SMAP) mission has an aggressive approach RFI detection and filtering using dedicated spaceflight hardware ground processing software. As more sensors push observe at larger bandwidths in unprotected or shared spectrum, continues be essential...
