Abstract :
A class of quaternary codes is described, and an algorithm for generating the codes is given. The codes have properties that make them useful for radar applications: 1) their auto-correlation consists of a single pulse, 2) their length can be any power of two, 3) each code can be paired with another code (its mate) of the same class in such a way that the crosscorrelation of mates is identically zero, 4) coded waveforms can be generated in a simple network the number of whose elements is proportional to the base-2 logarithm of the code length, and 5) the same network can be readily converted to a matched filter for the coded waveform.
