Multilateration for geolocation of targets

Abstract

Disclosed are systems, methods, and computer programs for determining a range to a target. A system can include a first receiver configured for receiving a first signal from the target and a second receiver configured for receiving a second signal from the target, the second receiver time-synchronized with the first receiver. A programmable processor can determine a range to the target based on arrival times of the first signal at the first receiver and the second signal at the second receiver.
