  Automotive radar is a key component in an ADAS. The increasing number of
radars implemented in vehicles makes interference between them a noteworthy
issue. One method of interference mitigation is to limit the TBP of radar
waveforms. However, the problems of how much TBP is necessary and how to
optimally utilize the limited TBP have not been addressed. We take CWS as an
example and propose a method of designing the radar waveform parameters
oriented by the performance of CWS We propose a metric to quantify the CWS
performance and study how the radar waveform parameters (bandwidth and
duration) influence this metric. Then, the waveform parameters are designed
with a limit on the TBP to optimize the system performance. Numerical results
show that the proposed design outperforms the state-of-the-art parameter
settings in terms of system performance and resource or energy efficiency.
