A wireless transmitter and array receiver apparatus for receiving input from one or more wireless radio transmitting devices employs a spread spectrum signaling arrangement to transmit signals from the devices for identification and location determination. Spread spectrum techniques may include DSSS, FHSS, THSS, chirp, or combinations thereof. Passive transmitter devices operate in the propagation medium and radiate EM energy to signal receivers, where radiated signal-strength and carrier-phase difference measurement techniques are used to determine location, and spread spectrum encoding is used to identify the devices. Transmitter devices may generate one or a plurality of data signals that are spread spectrum encoded, to be decoded by said receiver. One or a plurality of transmitter signals are received, located, and identified by the SS methods and use ASK and FSK data modulation schemes to reduce the effects of signal multi-path and occlusion.
