Abstract : The patent relates to a digital tracking range unit using (passive) correllation techniques. A pseudo-random noise signal is generated and transmitted by the station or object from which the range is to be determined. This signal is received at the range tracking station and passed to a signal comparator unit which correlates this signal with a self-generated signal of the same pattern. If the two signals are coincident in time an output will result from the correlator.
