Abstract

Pseudo random codes are easily constructed and can be used in multiple-input multiple-output (MIMO) radar to provide for signal separation. However it has the drawbacks of high aperiodic cross-correlation and auto-correlation sidelobes. Fortunately, in some applications, codes with low correlations are needed only over a narrow window. In this paper, we introduce the Zero Correlation Zone Codes (ZCZC) which have zero correlations in a narrow zone. In other applications, the targets are stationary, which allows for using a long code sequence. In this case we propose an Extended Zero Correlation Zone Codes (EZCZC) where the zero correlation zone is extended to cover the whole sidelobes area. Design examples are given.
