ASSOCIATING SIGNAL INTELLIGENCE TO OBJECTS VIA RESIDUAL REDUCTION
First Claim
1. A method comprising:
- 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 SIGnal INTelligence (SIGINT) signal received at each of the collectors; and
determining a likelihood that the first signal corresponds to the SIGINT signal to determine whether the SIGINT signal was transmitted from a transmitter on the corresponding 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.

15. A device configured to determine which tracklet of a plurality of tracklets extracted from video data hat a SIGnal INTelligence (SIGINT) event originated from, the device comprising:
-
a processor configured to; estimate 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; compare each estimated ToA to a respective actual ToA of a SIGnal INTelligence (SIGINT) signal received at each of the collectors; and determine a likelihood that the first signal corresponds to the SIGINT signal to determine whether the SIGINT signal was transmitted from a transmitter on the corresponding tracklet. - View Dependent Claims (16, 17, 18, 19, 20)
