Designing Radar Waveform Parameters Oriented to Performance of Collision Warning System

With the popularization of automotive radars, mutual interference among them becomes a noteworthy issue. One countermeasure is to improve the efficiency of radar's use of electromagnetic resources based on the performance of automotive system. In this paper, we take the collision warning system as an example and propose a method of designing the radar waveform parameters oriented by system performance. We propose total wrong decision loss as the metric to quantify the performance and study the relationship between this metric and radar waveform parameters (bandwidth and duration). Then, the waveform parameters are designed with a limit on the electromagnetic resources 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.
