摘要

先进的驾驶辅助系统和自动驾驶应用使用雷达传感器来实现不同的安全功能。使用雷达在方位角维度上的高分辨率可以促进这些应用(例如停车)。然而,这些安全关键应用都是在内存有限、计算能力有限的嵌入式系统上实现的,需要对乘客的安全做出实时反应。通过合成孔径雷达(SAR)信号处理,可以获得更高分辨率的环境表征。本文讨论了一种适用于汽车应用的SAR概念的实时嵌入式系统实现。讨论了系统概念的计算和内存消耗方面,并通过集成汽车微控制器中的实际测量进行了验证。

Real-Time Synthetic Aperture Radar for Automotive Embedded Systems
Advanced driver assistance systems and automated driving applications use radar sensors for different safety features. High resolution in azimuth dimension using radar can facilitate these applications (e.g. parking). However, these safety critical applications are realized on embedded systems with finite memory and computational power and need to react in real-time for passenger safety. With synthetic aperture radar (SAR) signal processing, it is possible to get a higher resolution representation of the environment. In this paper, we discuss a real-time embedded system realization of a SAR concept suitable for automotive applications. The computational and memory consumption aspects of the system concept are discussed and verified through real-world measurements in an integrated automotive microcontroller.
