A need exists to de-interleave different emitters active in multiple access communications environments. Tracking of emissions from a given user is a significant problem. A major difficulty is presented by the fact that the gross signal characteristics of all users are generally equivalent, since each user must satisfy joint communication system signal and protocol requirements. GMF proposes to adapt radar-based sorting algorithms for application to networked communications signal sorting. GMF is presently providing advanced technology in radar signal sorting to the Air Force, and has been recognized by the Air Force as a major contributor and innovator in this area. Radar-based signal sorting techniques of potential interest for this application include those which utlize intrinsic emitter parameters (e.g., PRI), extrinsic emitter parameters (e.g., geometric), and emitter signal intrapulse characteristics. GMF will make use, in this proposed effort, of its prior experience in applications of sorting technology to communications signals.
