ABSTRACT:
In a radar installation for measuring distances by transmitting and receig signal modulated by sequences of pseudo-random bits, generation both of the sequence of pseudo-random bits and of corresponding sequences with which the received radar signal is correlated, is controlled by a variable frequency clock. The frequency of the clock is varied to maximize the peak of the correlation function and the resulting frequency used to indicate the radar-target distance.
