要約(英語): In recent years, railway monitoring technologies that detect vehicles and pedestrians in railway environments such as platforms or railroad crossings have been developed. FMCW (frequency modulation continuous wave) radar for railway monitoring has been also reported. However, reflected signals having small power such as signals from pedestrians, are blocked by those from stationary objects such as the ground, because the signal components associated with stationary objects are diffused over the spectrum. Therefore, the authors have proposed stepped multiple frequency CPC (complementary phase code) radar, which can separate moving objects from stationary objects by estimating Doppler frequency. In this paper, we compare the basic performance of Stepped Multiple Frequency CPC with FMCW in a single target situation including many stationary objects at first. Next, the fundamental experiment results in railway environments, a platform and a railway crossing are shown. The results indicate that the developed radar could detect the target and obtain the velocities and ranges in such situations. In addition, experimental results with the radar fitted on the train are also shown.
