This radiometer forms part of a remote sensing payload, uses space qualified components and requires minimum power, volume and mass. Radiometer Front End.... The overall system performance for the complete front end unit, including all RF coupling losses, is typically <3, 500 K in each channel, achieving a radiometric minimum detectable sensitivity of <1 deg K in a 20mS integration period. This performance is achieved for a fully environmentally specified instrument at nominal ambient temperatures.  2, fiche 1, Anglais, - radiometer%20front%20end

For the receiver, Garrison and Katzberg used a commercially available GPS-development kit, which included a 12-channel correlator chip fed by two radio-frequency(RF) front ends. They employed a zenith-oriented RHCP antenna mounted on top of an aircraft fuselage to receive the direct signal through one RF front end. A nadir-oriented LHCP antenna located on the bottom of the fuselage received the reflected signal through the other RF front end.  2, fiche 2, Anglais, - RF%20front%20end
