Latest Patents

One of his latest patents is titled "Geolocating a Remote Emitter." This invention presents a method for improving geolocation accuracy in a passive radar warning receiver. It utilizes synchronized data curve-fit and interpolation to address inaccuracies caused by noise in receiver and navigation measurements. The method generates synchronized data samples at intervals short enough to ensure that constant-rate equations remain valid, even when actual motions are complex. This innovation effectively reduces noise and enhances measurement accuracy.

Another significant patent is "Frequency Difference of Arrival (FDOA) for Geolocation." This method determines the FDOA of a pulsed waveform received by two sensors. It involves obtaining a plurality of in-phase and quadrature-phase samples indicative of the pulse envelope. The method refines the approximation of the time difference of arrival (TDOA) through interpolation of cross-correlation amplitudes, ultimately determining the FDOA.
