Soil Moisture Active/Passive (SMAP) L-Band Microwave Radiometer Post-Launch Calibration
Abstract— The SMAP microwave radiometer is a fully-polarimetric L-band radiometer flown on the SMAP satellite in a 6 AM/ 6 PM sun-synchronous orbit at 685 km altitude. Since April, 2015, the radiometer is under calibration and validation to assess the quality of the radiometer L1B data product. Calibration methods including the SMAP L1B TA2TB (from Antenna Temperature (TA) to the Earth’s surf...
متن کاملFirst Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: On-Orbit Radiometer Characterization
The WMAP satellite has completed one year of measurements of the Cosmic Microwave Background (CMB) radiation using 20 differential high-electron-mobility-transistor (HEMT) based radiometers. All the radiometers are functioning nominally, and characterizations of the on-orbit radiometer performance are presented, with an emphasis on properties that are required for the production of sky maps fro...
متن کاملOcean Vector Winds in Storms from the SMAP L-Band Radiometer
Our paper discusses the unique capability of the SMAP L-band radiometer to measure strong winds in tropical and extratropical cyclones. There is no significant degradation in rain. INTRODUCTION AND OUTLINE The Soil Moisture Active Passive Mission SMAP (Entekhabi et al., 2010) was launched in January 2015 and has been providing science data since April 2015. Though designed to measure soil moist...
متن کاملDesign of an L-Band Microwave Radiometer with Active Mitigation of Interference
For increased sensitivity in L-band radiometry, bandwidths on the order of 100 MHz are desirable. This will likely require active countermeasures to mitigate RFI. In this paper, we describe a new radiometer which coherently samples 100 MHz of spectrum and applies realtime RFI mitigation techniques using FPGAs. A field test of an interim version of this design in a radio astronomy observation co...
متن کاملDesign and First Results of an UAV-Borne L-Band Radiometer for Multiple Monitoring Purposes
UAV (unmanned Aerial Vehicle) platforms represent a challenging opportunity for the deployment of a number of remote sensors. These vehicles are a cost-effective option in front of manned aerial vehicles (planes and helicopters), are easy to deploy due to the short runways needed, and they allow users to meet the critical requirements of the spatial and temporal resolutions imposed by the instr...
