发明名称 Distance separation tracking system
摘要 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.

主权项 1. A distance separation tracking process comprising: transmitting a periodic radio frequency original signal from a beacon transceiver as a signal packet as a disruption on an audio channel of a radio system to provide the distance separation tracking capability, 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; conveying the target received periodic signal to a transmitter within said target transceiver by way of a hardwired loop connect; retransmitting the target received periodic signal to said beacon transceiver as a return periodic signal; sampling data points of said return periodic signal, a receiver in said beacon transceiver providing a signal strength measurement for said return periodic signal directly to a microprocessor in said beacon transceiver; 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 based on the signal strength measurements without adjusting a gain loop of the receiver; and wherein said distance separation is determined in spite of intermediate obstructions and without reliance on GPS, clock synchronization, or line of sight.
