The MIMO ambiguity functions of the binary phase codes as applied to phase-coded frequency modulated continuous waveform (PC-FMCW) are studied. The range-angle performance of the PC-FMCW with different code families is investigated and compared with the phase modulated continuous waveform (PMCW). An advantage of the PC-FMCW ambiguity function over the PMCW one is demonstrated in terms of the range resolution and sidelobe level for the same types of codes.
