79GHz周辺監視レーダにおける車両の方位別RCS特性比較

抄録

Vehicle radar has recently attracted considerable for assist in safe driving and self-driving because it overcomes the shortcomings of laser and camera. Eventually, ultra-wideband (UWB) radar would be able to detect some objects even in bad weather condition such as fog, dust and rain. It is important to understand the radar cross section (RCS) characteristics of various type of vehicles in vehicle radar. However, in the perimeter monitoring situation in the vehicle radar, the entire circumference of the vehicle is not detected. In this paper, the direction of the detection target is divided into three parts corresponding to the purpose of the Perimeter monitoring radar, and the RCS characteristics for each orientation of three kinds of vehicles are compared in the 79GHz band. For comparison of frequency characteristics, the same experiment was conducted in the 10GHz band and the 24GHz band. As a result, the frequency characteristics of the azimuth angle RCS for each model showed different trends. In addition, we confirmed that the azimuth angle RCS characteristics is divided into Log-normal and Log-Weibull.
