ALEXANDRIA, Va., Feb. 17 -- United States Patent no. 12,553,985, issued on Feb. 17.
"Geolocation system using Nyquist-folding receivers" was invented by Kevin J Rappoport (Evans, Ga.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A geolocation system for efficiently reconstructing and geolocating signals collected in multiple spatially-distributed sensors using a plurality of different Nyquist-folding samplers operating at sub-Nyquist rates. The sensors use Nyquist-folding with a plurality of sampling rates and patterns to reduce the volume of data transmitted off the sensor while retaining the ability to detect weak signals, and produce high-quality signal reconstructions and geolocations. The ambiguities i...
