The group-complimentary codes provide sets of binary word groups which have the combined properties of optimized aperiodic autocorrelation and optimized cross-correlation between word sets. The optimized aperiodic autocorrelation property allows the implementation of pulse compression processing in sensor systems to achieve zero value temporal or range sidelobes within the principal interpulse period without resorting to weighting techniques for sidelobe reduction. The orthogonal nature of group-comlementary codes, apparent from their absence of cross-correlation between sets, allows sensors to be deployed in close proximity, using the same carrier frequency without direct path mutual interference when synchronized.
