| Abstract(J) | アメダス等に代表される公開気象データを利用した車載ミリ波レーダ上の湿雪着雪による受信信号の低減率を表す式を提案する．当該式導出にあたっては，着雪の含水率と厚さを変えたミリ波レーダの信号低減試験と，平板上の着雪成長を求める着雪風洞試験を実施した．提案式は降雪の含水率と空間密度，及び時間の関数となる． Translation |
| Abstract(E) | We propose an equation representing the reduction rate of received signals on in-vehicle millimetre-wave radars due to wet snow accumulation utilising publicly available meteorological data such as those from the Automated Meteorological Data Acquisition System. To derive this equation, we conducted signal reduction tests on millimetre-wave radars with varying the liquid water content(LWC) and thickness of snow specimen, alongside wind tunnel tests measuring snow accumulation growth on flat plates. The proposed equation is a function of the LWC and spatial density of the falling snow, as well as time. |
