Millimeter-wave phase-coded CW MIMO radar using zero-correlation-zone sequence sets

We present a phase-coded continuous-wave (CW) multiple-input multiple-output (MIMO) radar approach based on code-division multiplexing. We use zero-correlation-zone (ZCZ) sequence sets to separate at the receivers signals from multiple transmitters. In particular, our approach uses equidistantly shifted almost-perfect autocorrelation sequences for efficient implementation. We carried out measurements using a software-defined radar platform with 16 MIMO channels to demonstrate the capability of the proposed approach.
