The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission was recently selected by NASA as part of the Earth Venture Instrument (EVI-3) program. The overarching goal for TROPICS is to provide nearly all-weather observations of 3-D temperature and humidity, as well as cloud ice and precipitation horizontal structure, at high temporal...
Recent advances in low-power millimeterwave low-noise amplifier technologies have enabled the hosting of high-performance atmospheric sounding instruments on very small satellites. Microwave instrumentation is particularly well suited for such implementations, as the sensor requirements for power, pointing, and spatial resolution (aperture size) can readily be accommodated by a nanosatellite platform...

A project to design and construct an airborne 8 mm band 2-Dimensional (2D) aperture synthesis radiometer BHU-2D was launched in the Electromagnetics Laboratory of BeiHang University (BHU). BHU-2D consists of 48 antenna/receiver elements, an FPGA-based 1 bit/2 levels digital cross-correlation subsystem, and a calibration subsystem. A ground based laboratory prototype of BHU-2D has been completed, which...
