Verification of Applicability of 90 GHz Band Millimeter‐Wave for Obstacle Detection to Railway
IEEJ Transactions on Electrical and Electronic Engineering, Volume 18, Issue 6, Page 960-969, May 2023., 2023 Abstract Obstacles on railway tracks are a factor hindering safe and stable operation. For this reason, obstacle detection systems have been introduced at level crossings, slopes and under platforms. However, they have been introduced only in limited sections for limited applications.
