  • Geolocation method for detection and tracking of maneuvering emitters
    Patent number: 12716985
    Abstract: A method includes receiving, using radio frequency (RF) collectors, RF signals from a target object. The RF signals of target object may be converted to In-phase and Quadrature (I/Q) data. Navigation data of each RF collector may be determined and I/Q data of each of RF collectors are paired. Processing functions may be applied on paired I/Q data. Using paired I/Q data, one or more of time difference of arrival (TDOA) measurement data and frequency difference of arrival (FDOA) measurement data between each pair of the RF collectors are determined. One or more of TDOA measurement data, FDOA measurement data and navigation data of each RF collector are converted to message data. A trajectory of target object may be estimated based on confidence measure of one or more of TDOA and FDOA measurement data. Using estimated trajectory of target object for displaying on a display device of a computing device.
