An FPGA-based implementation of the measurer by time-delay is proposed which with the correlation post-detection processing of the pseudo-noise signal. The measurement method is based on real-time calculation of the mutual correlation function between the reference, repeating the modulation law, and the received signals. The experimental results are presented produced with a proto-type of the developed system in acousto- hydro- and radiolocation.
