ABSTRACT:
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.
