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.
