Code mates having cooperating autocorrelation functions to produce an impulse autocorrelation function are utilized. The code is bi-phase generated with phases of 0 DEG and 180 DEG and the mate code is bi-phase generated with phases of +90 DEG and -90 DEG . The resultant outputs are linearly combined to yield a single quaternary or quintuple code of the pseudo-noise class, that is, an impulse autocorrelation function. The quaternary code results when the code mates are binary codes. The quintuple code results when the code mates are ternary codes, where no output represents the third code.
