Abstract

We produce new phase coded waveforms, by concatenating two sequences from two different families of CAZAC codes. In particular, we consider two pairs of families: Wiener and Bjorck codes, and Chu-Zadoff and P4 codes. For both pairs, equally proportioned systems generate signals with reduced sidelobes, at nonzero low Doppler shifts. The 50%-50% concatenated Wiener and Bjorck systems lead to signals with improved autocorrelation and detection-tracking performance.
