US 2011/0148710 A1 · DISTANCE SEPARATION TRACKING SYSTEM

Abstract

A distance separation tracking process is provided that includes the transmission of a periodic radio frequency original signal from a beacon transceiver. The original periodic signal from the beacon transceiver is received at a remote target transceiver as a target received periodic signal. The target retransmits the received periodic signal to the beacon transceiver as a return periodic signal. Data points of the return periodic signal are sampled and used to calculate a phase differential between the original periodic signal and the return periodic signal that correlates to the distance separation range between the beacon transceiver and the target transceiver.

Dependent claims

A distance separation tracking process comprising:

transmitting a periodic radio frequency original signal from a beacon transceiver, said original signal being defined by a mathematical equation;
receiving the original periodic signal from said beacon transceiver at a remote target transceiver as a target received periodic signal;
retransmitting the target received periodic signal to said beacon transceiver as a return periodic signal;
sampling data points of said return periodic signal;
and
calculating a phase differential between the original periodic signal and the returned periodic signal correlating to a distance separation range between said beacon transceiver and said target transceiver.
