论文摘要
汽车雷达是ADA中的关键组件。车辆中实施的雷达数量的增加使它们之间的干扰是一个值得注意的问题。一种减轻干扰的方法是限制雷达波形的TBP。但是，尚未解决需要多少TBP以及如何最佳利用有限的TBP的问题。我们以CWS为例，并提出了一种通过CWS性能设计的雷达波形参数的方法，我们提出了一个度量标准来量化CWS性能并研究雷达波形参数（带宽和持续时间）如何影响该度量。然后，设计波形参数对TBP的限制设计以优化系统性能。数值结果表明，在系统性能，资源或能源效率方面，所提出的设计优于最新参数设置。
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.
