Optimized Punctured ZCZ Sequence-Pair Set: Pair Set: Design, Analysis, and Application to Radar System

Based on the Zero Correlation Zone (ZCZ) concept, the authors present the definitions and properties of a set of new ternary codes, ZCZ sequence-Pair Set (ZCZPS), and propose a method to use the optimized punctured sequence-pair along with Hadamard matrix to construct an Optimized Punctured ZCZ Sequence-Pair Set (OPZCZPS) which has ideal autocorrelation and cross-correlation properties in the zero correlation zone. Considering the moving target radar system, the correlation properties of the codes will not be severely affected when Doppler shift is not large.
