A system for determining properties of a radiant energy beam. The system include a plurality of fiber optic cables each including a first end and a second end and a plurality of optical coupling nodes coupled to a target body, wherein each optical coupling node includes one or more terminations, wherein each termination is coupled to the first end of one of the plurality of fiber optical cables to receive radiant energy from an incident radiant energy beam to determine properties of the radiant energy beam.

Energy target system

A system and method for determining the geolocation of a signal emitter moving at an unknown velocity by combining signal data of a target detection platform (e.g., a radar system) and signal data collected by two or more moving signal collection platforms (e.g., RF signal receivers). In one embodiment, the target detection platform determines tentative location and velocity of the signal emitter, and the signal collection platforms are configured to perform TDOA and/or FDOA analysis of the collected signal data corresponding to a signal of the signal emitter. In one embodiment, solutions provided from the TDOA and/or FDOA analysis are unbiased by using the tentative velocity of the signal emitter, and the geolocation of the signal emitter is determined by matching the TDOA/FDOA solutions and the detected tentative location.
