Abstract

Automotive radar sensors will be used in many future applications to increase comfort and safety. Adaptive cruise control (ACC), parking aid, collision warning or avoidance and pre crash are some automotive applications, which are based on high performance radar sensors. This paper describes results gained by an European Commission funded research project and a new radar network based on four individual monostatic 77 GHz FMCW radar sensors. Each sensor measures target range and velocity simultaneously and extremely accurate even in multiple target situations with a maximum range of 40 m. The azimuth angle is estimated by multilateration techniques in a radar network architecture. The system design and the signal processing of this network are described in detail in this paper. Due to the high range resolution performance of each radar sensor ordinary targets cannot be considered any longer as point but as extended targets. System capability, performance and reliability can be improved essentially if the single sensor FMCW signal processing, the target position processing in the radar network and the tracking scheme are jointly optimized.

基于77 GHz FMCW传感器的汽车雷达网络

汽车雷达传感器将在未来的许多应用中使用，以提高舒适性和安全性。自适应巡航控制(ACC)、停车辅助、碰撞警告或避免以及预碰撞是一些基于高性能雷达传感器的汽车应用。本文描述了一个欧盟委员会资助的研究项目和一个基于四个单独的单站77 GHz FMCW雷达传感器的新雷达网络所获得的结果。每个传感器同时测量目标距离和速度，即使在多目标情况下也非常准确，最大范围为40米。在雷达网络结构中，采用多倍体技术估计方位角。本文详细介绍了该网络的系统设计和信号处理。由于各雷达传感器的高距离分辨率性能，普通目标不再被视为点，而被视为扩展目标。将单传感器FMCW信号处理、雷达网络中目标位置处理和跟踪方案进行联合优化，可以从根本上提高系统的性能、性能和可靠性。
