摘要

车内监控系统（iCM）正在改变汽车行业对安全和乘员健康的态度。在各种传感技术中，雷达已成为一种高效的解决方案，因为它在光线不足或视野受阻等具有挑战性的条件下具有鲁棒性。本文回顾了用于关键汽车安全应用的最先进的雷达技术，包括儿童存在检测（CPD）、安全带提醒（SBR）、入侵检测系统（IDS）、乘员失位（OOP）分析和生命体征监测。随着欧洲新车评估计划（Euro NCAP）标准强制要求CPD和SBR等监管要求的出现，雷达技术为汽车制造商提供了一种可扩展的、经济高效的解决方案。本文探讨了iCM使用的三种主要雷达技术[多普勒、调频连续波（FMCW）和超宽带（UWB）]的基本雷达原理、系统架构、功能和局限性，解决了提高车辆安全性的技术挑战和机遇。

Automotive In-Cabin Radar Uncovered: The Essential Guide to Choose the Perfect Sensing Technology for Your Vehicle

In-cabin monitoring systems (iCM) are transforming the automotive industry’s approach to safety and occupant well-being. Among the various sensing technologies, radar has emerged as a highly effective solution due to its robustness in challenging conditions such as poor lighting or obstructed view. This article reviews the state-of-the-art radar technologies used for critical automotive safety applications, including child presence detection (CPD), seat belt reminder (SBR), intrusion detection systems (IDS), occupant out-of-position (OOP) analysis, and vital sign monitoring. With emerging regulatory requirements, such as the European New Car Assessment Program (Euro NCAP) standards mandating CPD and SBR, radar technology provides a scalable, cost-effective solution for automakers. This article examines the underlying radar principles, system architectures, capabilities, and limitations of the three main used radar technologies [Doppler, frequency modulated continuous wave (FMCW), and ultrawideband (UWB)] for iCM, addressing both technical challenges and opportunities for enhancing vehicle safety.

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
