Abstract :
The performances of generated test code sets are compared to other phase coding and theoretical limits. The results presented show that the generation algorithm produces uniform amplitude complex code sets with low autocorrelation sidelobes and low cross-correlation outputs. The mainlobe to peak sidelobe ratio (MPSR) gains over binary codes could lead to significant performance improvements in both communication and radar systems that require multiple codes. The Doppler characteristics of the generated codes are comparable to those of binary phase codes. Although the generation times are long, they are not impractical given current and projected processing technology
