The invention provides a train operation control method and system based on millimeter wave radar, and the method comprises the steps: obtaining a plurality of target positioning pulse signals, each target positioning pulse signal is obtained by adding acquisition timestamp information to an acquired spread spectrum Doppler pulse wave by a millimeter wave base station corresponding to a target train driving area; the spread spectrum Doppler pulse wave is sent by a vehicle-mounted positioning radar arranged on the target train, and the millimeter wave base station is arranged in a track area where the target train runs; calculating a signal time difference of spread spectrum Doppler pulse waves received by two adjacent millimeter wave base stations according to timestamp information in the plurality of target positioning pulse signals; according to the multiple signal time differences, position information of the target train is obtained through calculation, and operation positioning is conducted on the target train according to the position information. According to the invention, high-precision positioning of the target train is realized, and the positioning efficiency is improved.
