DARPA seeks to transform radio frequency (RF) systems by developing RF analog signal processing and nonreciprocal technologies that perform unprecedented levels of in-band interference suppression.
The Signal Processing at RF (SPAR) technology aims to mitigate both self and externally generated
interfering signals of known and unknown characteristics.
The goal of SPAR is to demonstrate novel in-band signal interference mitigation technologies using analog signal processing techniques as well as novel chip-scale circulator approaches.
