A noise source is an enabling technology for passive millimeter-wave remote sensing applications such as atmospheric sounding, and precipitation and ice cloud measurements. NASA Goddard Space Flight Center has developed a packaged noise source that will allow calibration of the front end at the sensing frequency. This capability will eliminate or reduce the requirement of a clear view to cold space, which will reduce the mass and complexity as well as the total cost of the system.
