In Japan, automatic train operation has been introduced on a restricted number of lines, such as those with no level crossings. More recently there have been plans to expand the introduction of automatic train operation to conventional lines which have level crossings, which increases the importance of having methods for automatically detecting humans and obstacles on railway lines. This paper introduces a test system using 90 GHz band millimeterwave radar and reports the results of tests conducted to confirm its performance specifically for detecting the position of humans on railway tracks. The paper also presents future plans for building a comprehensive railway track monitoring system using 90 GHz band millimeterwave radar.
