Collision Avoidance has received serious attention in the automotive research area. There are two methodologies for collision avoidance systems: Sensor-based and ITS-based. The main goal of this work is to provide a comprehensive review of both sensor-based and ITS-based collision avoidance systems. A comparative analysis between these two methodologies and a description of possible future research...
The radar signatures of automotive targets were measured from 22 to 29 GHz and 76 to 81 GHz inside an anechoic chamber using a vector network analyzer. Radar cross section maps of a sedan, truck, van, pedestrian, motorcycle, and bicycle as a function of effective radar sensor bandwidth, center frequency, and polarization are presented.
We discuss the unique requirements of automotive active safety systems which drive the challenging specifications of next-generation automotive short range radar sensors. Sensor level performance, vehicle integration, worldwide regulation, cost, and reliability are highlighted, along with possible paths towards achieving future performance metrics.
