Associating signal intelligence to objects via residual reduction
First Claim
1. A method for associating tracklets extracted from video data with SIGnal INTelligence (SIGINT) signals, each tracklet identifying geolocations of a respective moving object in the video data, the method comprising:
- determining, using a processing unit, a plurality of time estimates, each of the time estimates representing an estimated amount of time it takes for a first signal to travel from a geolocation of a respective tracklet of the tracklets to travel to a respective collector of a plurality of collectors;
adding, using the processing unit, each of the time estimates to a video capture time, the video capture time indicating a time at which an object was at the geolocation of the respective tracklet to create estimated time of arrivals (ToAs);
comparing, using the processing unit, each of the estimated ToAs to actual ToAs to determine which estimated ToAs are closest to the actual ToAs, the actual ToAs indicating a time at which a SIGINT signal of the SIGINT signals was received at each of the collectors; and
associating the WANT signal with a tracklet of the tracklets corresponding to the estimated ToAs determined to be closest to the actual ToAs to associate the object with the tracklet.

Abstract
Generally discussed herein are systems and apparatuses that are configured to and techniques for associating a SIGnal INTelligence (SIGINT) signal with an object or tracklet. According to an example a technique can include estimating Times of Arrival (ToAs) at each of a plurality of collectors of a first signal from each of a plurality of moving transmitters, each first signal transmitted from a transmitter on a tracklet extracted from video data and received at the plurality of collectors, wherein a location of each of the plurality of collectors is known, comparing each estimated ToA to a respective actual ToA of a SIGINT signal received at each of the collectors, or determining a likelihood that the signal corresponds to the SIGINT signal to determine whether the SIGINT signal was transmitted from a transmitter on the corresponding tracklet.

8. A non-transitory machine-readable storage device including instructions stored thereon, the instructions, which when executed by a machine, cause the machine to perform operations for associating tracklets extracted from video data with SIGnal INTelligence (SIGINT) signals, each tracklet identifying geolocations of a moving object in the video data, the operations comprising:
-
determining a plurality of time estimates, each of the plurality of time estimates estimating an amount of time it takes for a first signal to travel from a geolocation of a respective tracklet of the tracklets to travel to a respective collector of a plurality of collectors; adding each of the time estimates to a video capture time, the video capture time indicating a time at which an object was at the geolocation of the respective tracklet to create estimated time of arrivals (ToAs); comparing each of the estimated ToAs to actual ToAs to determine which estimated ToAs are closest to the actual ToAs, the actual ToAs indicating a time at which a SIGINT signal of the SIGINT signals was received at each of the plurality of collectors; and associating the SIGINT signal with a tracklet of the tracklets corresponding to the estimated ToAs determined to be closest to the actual ToAs. - View Dependent Claims (9, 10, 11, 12, 13, 14)

-
a processor configured to; determine a plurality of time estimates, each of the plurality of time estimates estimating an amount of time it takes for a first signal to travel from a geolocation of a respective tracklet of the tracklets to travel to a respective collector of a plurality of collectors; add each of the time estimates to a video capture time, the video capture time indicating a time at which an object was at the geolocation of the respective tracklet to create estimated time of arrivals (ToAs); compare each of the estimated ToAs to actual ToAs to determine which estimated ToAs are closest to the actual ToAs, the actual ToAs indicating a time at which a SIGINT signal of the SIGINT signals was received at each of the plurality of collectors; and associate the SIGINT signal with a tracklet of the tracklets corresponding to the estimated ToAs determined to be closest to the actual ToAs. - View Dependent Claims (16, 17, 18, 19, 20)
