  We consider a bistatic vehicular integrated sensing and communications (ISAC)
system that employs the recently proposed orthogonal chirp division
multiplexing (OCDM) multicarrier waveform. As a stand-alone communications
waveform, OCDM has been shown to be robust against the interference in
time-frequency selective channels. In a bistatic ISAC, we exploit this property
to develop efficient receive processing algorithms that achieve high target
resolution as well as high communications rate. We derive statistical bounds
for our proposed Sequential symbol decoding and radar parameter estimation
(SUNDAE) algorithm and compare its competitive performance with other
multicarrier waveforms through numerical experiments.
