Abstract

Collision avoidance radar for trains is significant for safe transportation. In order to realize a low cost collision avoidance radar and high performance of azimuth accuracy, we have developed MMW (millimetre wave) radar, which employs switched phased array and frequency stepped technology. This paper analyses the radiation patterns of transmitting/receiving antennas and compensation method for amplitude/phase errors of synthetic wideband frequency stepped radar. To confirm the operation of the radar, low cost millimetre-wave collision avoidance radar was fabricated. Lots of experiments confirmed a high azimuth and range resolution.
