The invention discloses a rail transit train high and low frequency combined distance measurement system and method. The system comprises dual-frequency distance measurement devices and a dual-frequency directional antenna. The dual-frequency distance measurement devices are arranged at the head and the tail of a train, and each dual-frequency distance measurement device comprises a high-frequency distance measurement module with a working frequency higher than 5.8 Ghz and a low-frequency distance measurement module with the working frequency lower than 5.8 Ghz. The high-frequency distance measuring module and the low-frequency distance measuring module both adopt a master-slave framework, and the dual-frequency directional antenna comprises a forward antenna which is mounted on the train head and is arranged corresponding to the dual-frequency distance measuring device of the train head, and a backward antenna which is mounted on the train tail and is arranged corresponding to the dual-frequency distance measuring device of the train tail. According to the invention, the distance and precision of distance measurement can be effectively considered through a high-frequency and low-frequency combined distance measurement method.
