Various technologies for identifying RF emitters in geolocation datasets are described herein. Doppler signatures of RF emitters and geolocation data of objects in a scene are collected simultaneously, then range-rate profiles of the movement of the RF emitters and the objects in the scene are computed. An RF emitter is identified in a geolocation dataset by comparing the motion of the RF emitter with the motion of an object in the scene as described by the respective range-rate profiles.
