A target tracking system tracks the position of a vehicle, such as a racing vehicle. An oscillator is positioned at the target to be tracked, and a transmitter is also positioned at the target for transmitting a signal generated by the oscillator. At least three translators receive the signal transmitted from the target and each retransmits the signal to a base receiving station. The base receiving station also receives the signal sent from the target and includes a comparator for comparing each of the signals received from the translator with the signal sent directly from the target. The output of the comparator provides an indication of the position of the target relative to the base receiving station.

DETAILED DESCRIPTION Accordingly the invention consists of a target tracking system comprising an oscillator, a transmitter to transmit a signal representative of the signal generated by said oscillator at substantially a selected frequency, at least three translators to receive the transmitted signal and retransmit that signal to a base receiving station which also receives a direct signal from the transmitter, and means to compare the received signals to thereby track the target.
To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the scope of the invention as defined in the appended claims.
The disclosures and the descriptions herein are purely illustrative and are not intended to be in any sense limiting.
