| Abstract(J) | DIVPプロジェクトでは自動運転の安全検証を仮想空間で行うシミュレータを開発しており，降雪時のセンサ性能を仮想空間で実現する課題にも取り組んでいる．昨年は，雪表面からのミリ波や光の反射特性について報告した．ミリ波は雪を透過する性質も持つことから，今年度は，路面の上に雪が積もっている場合について，雪と路面の多層から反射されたミリ波の特性を測定するとともに，S行列を用いた計算モデルを構築した．雪厚を変化させながら実験を行った結果，実測とモデル計算値はよく一致した． Translation |
| Abstract(E) | For safety validations of automated driving vehicles, simulators in the cyber world are important. The DIVP project is developing a simulator to reflect real environment including snowy weather condition. Last year, reflections from snow surface regarding light and millimeter wave were reported at JSAE. Essentially, millimeter wave can penetrate snow to some extent. Considering real snow-covered road condition, characteristics of multiple reflections from snow and road surface material in millimeter wave are measured. Also, the mathematical model using S-function to calculate multiple reflections are created. Experiments were conducted while varying the thickness of the snow on road surface material. Measured results are well matched with the model. |
