Modern military radios for SIGINT or communication applications often need to operate in an interferer-rich environment. They typically need to quickly find interferers or jammers, both spectrally and spatially, to take appropriate countermeasures. We show how compressive sampling CS can enable unique RF capabilities and performance. The Direct-RF-to-Information Converter DRF2IC rapidly detects interferers or signals of interest SOI in the spectral domain and the Direct-Space-to-Information Converter DSIC rapidly detects their direction of arrival in the spatial domain. Thanks to CS, the SOIs are found quickly while only requiring low energy. We demonstrate RF ICs of these converters implemented as overlays on high performance receivers and beamformers. Their speed, low energy, and unified architectures makes them excellent solutions in SWaP-constrained platforms like man-portable, satellite and unmanned aerial system UAS applications.
