Technical Abstract (Limit 2000 characters, approximately 200 words):

The proposed project aims to develop a board level solution for the NASA’s microwave correlation radiometers required for Earth sensing applications. Spaceborne instrumentation requires minimized size, weight and power (SWaP). Present solutions rely on analog signal processing, thus are bulky, power hungry and cannot be reprogrammed. Analog filter parameters tend to be unstable over temperature, power supply voltage, may degrade over time and need tuning.

The proposed approach will process an IF I/Q signal up to 10GHz, derived, for example, in water vapor sounders at 180GHz band. To implement the required function, a previously developed ASIC will be redesigned to improve its analog front-end performance and implement a new DSP function with the increased SEE immunity. Within the DSP block, IF input signals will be channelized into 64 bands and cross-correlated within each band. Several innovations will be introduced to the ASIC and the board level solution to combine improved performance, programmability, minimized SWaP and radiation sensitivity. 

The project’s Phase I will provide the proof of project’s feasibility. Phase II will provide a silicon proven ASIC and the board level solution for correlation radiometers.
