ABSTRACT:
A device for suppressing autocorrelation sidelobes in a pseudo-random coded radar system employing a phase-coded CW signal in which the phase code is preselected to have a predetermined symmetry. Autocorrelation is affected in the standard manner and also in respect to the transmitted code shifted by one bit in time. Summation of the two autocorrelation functions provides a new autocorrelation function in which the sidelobes between main correlation peaks are suppressed.
