Digital Back End for P-Band Reflections Concepts

A low cost, low power, and low mass P-band digital back end (DBE) has been developed at JPL. The design is based upon a Global Navigation Satellite System (GNSS) receiver (called Cion) that has been currently flying on the CICERO CubeSats. This paper describes the design of the DBE as well as use cases for the subsystem. This Cion DBE will be used in NASA InVest mission SNOOPI (SigNals of Opportunity P-Band Investigation) and an instrument incubator project Signals of Opportunity Synthetic Aperture Radar (SoOpSAR) to demonstrate SAR like processing using P-band Signals of Opportunity (SoOp).
