Hostile platform position location utilizing networked communications
First Claim
1. A communication system, comprising:
- a plurality of receivers and transmitters, each said transmitter for providing communication transmissions having deterministic data, each said receiver having the digital processing capability for correlating received transmission reflections of said deterministic data amongst said plurality of receivers, said transmission reflections of said deterministic data being from objects within said transmission range of a respective transmitter, said correlating including utilizing relatively weak multipath signals of said transmission reflections and the superimposition of external data therewith to provide a resulting data base of range reflections, said range reflections being provided to others of said plurality of receivers for processing to derive the environment and the locations and movements of objects without the use of a specific interrogation signal, thereby providing situational awareness.

Abstract
The communication system utilizes transmitters that provide communication transmissions having deterministic data. Receivers of the system have the digital processing capability for correlating received transmission reflections of the deterministic data amongst the receivers, the reflections of the deterministic data being from objects within the transmission range of a respective transmitter. The correlating includes utilizing relatively weak multipath signals of the transmission reflections and the superimposition of external data therewith to provide a resulting data base of range reflections. The range reflections are provided to others of said plurality of receivers for processing to derive the environment and the locations and movements of objects without the use of a specific interrogation signal, thereby providing situational awareness.
