SYSTEM AND METHOD FOR THREAT DETECTION
First Claim
1. A system for threat detection comprising:
- an imaging detector configured to detect radiation originating from at least one source of radiation over a pre-determined period of time or distance traveled; and
a processor coupled to the imaging detector, the processor configured to;
backproject the radiation detected onto a plurality of points in world space via an image reconstruction technique;
generate a first set of image pixels identifying a location of the source of radiation corresponding to each of the points in world space, the first set of image pixels indicating presence of all possible sources of radiation; and
generate a second set of image pixels from the radiation backprojected, identifying only one or more potential sources of threat via a threat detection algorithm.

Abstract
A system for threat detection is provided. The system includes an imaging detector configured to detect radiation originating from at least one source of radiation over a pre-determined period of time or distance traveled. The system also includes a processor coupled to the imaging detector. The processor is configured to backproject the radiation detected onto multiple points in world space via an image reconstruction technique. The processor is also configured to generate a first set of image pixels identifying a location of the source of radiation corresponding to each of the points in world space, wherein the first set of image pixels indicate presence of all possible sources of radiation. The processor is further configured to generate a second set of image pixels from the radiation backprojected, identifying only one or more potential sources of threat via a threat detection algorithm.
