| Abstract(J) | ミリ波レーダを用いた距離検出システムは，自動車の安全運転支援に広く利用されているが，レーダドームへの着雪がレーダ検出能力を低下させることが知られている．本研究では，79GHz帯の着雪の影響を調べるために，実験的に雪の厚さ及び含水率を変化させ，レーダ受信信号強度の減衰との関係を定量的に示すことができた． Translation |
| Abstract(E) | Currently, distance detection systems using millimeter-wave radar are widely used to assist safe driving of automobiles. Although millimeter waves are not susceptible to fog, rain, or snowfall, it is known that the detection capability of millimeter-wave radar is severely hampered by snow accretion on the radar dome during cold weather. However, there are very few previous studies on the capability reduction of the radar due to wet snow deposition. Therefore, in this study, we experimentally investigated the effect of snow accretion on radar at 79 GHz wavelengths changing the thickness and the liquid water content of snow with using artificially formed snow particles. The results quantitatively show the relationship between the thickness and the liquid water content of snow and the attenuation of the radar received signal strength. |
