Doppler-assisted sensor fusion
| DWPI Title: System for identifying radio frequency (RF) emitters in geolocation dataset, has RF emitter that is at location of object in scene based on comparing first range-rate profile of object and second range-rate profile of RF emitter |
| Abstract: 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. |
| Use: Sensor association system for identifying radio frequency (RF) emitters in geolocation dataset. |
| Advantage: The computing device is used in a system that permits a user to submit queries over stored geolocation and RF sensor data to identify particular RF emitters in a geolocation dataset after the collection of data is completed. |
| Novelty: The system (120) has an integrated circuit which is configured to perform acts. The location information for an object in a scene is received. The location information is received from a geolocation sensor. A doppler signature of a radio frequency (RF) emitter in the scene is received. The doppler signature is based on data output by an RF sensor. A first range-rate profile of the object in the scene relative to a location of the RF sensor is calculated based on the location information. A second range-rate profile of the RF emitter relative to the location of the RF sensor is calculated based on the doppler signature. A display (124) that responsive to the RF emitter is determined to be at the location of the object in the scene, presents an indication that the RF emitter is at the location of the object in the scene. |
