The wireless communication system comprises: a plurality of ground radio sets installed along a railway that carry out the transmission/reception of a radar signal with a first frequency and the transmission/reception of a communication signal with a second frequency; a vehicle radio set on a train that carries out the transmission/reception of a communication signal with the second frequency; and a switching control device that controls the switching of ground radio sets that are to communicate with the vehicle radio set based on the reception level of the radar signal. Furthermore, the configuration allows the ground radio sets that are not communicating with the vehicle radio set to transmit a radar signal, and allows the ground radio set that has started communicating with the vehicle radio set to transmit a radar signal and a communication signal.
