The invention discloses a TDOA (time difference of arrival) short baseline positioning method and a TDOA short baseline positioning system for accurately synchronizing a clock and a trigger signal, comprising N base stations, N wire bundles, a central station and a computer terminal, N being greater than or equal to 3; comprising the following steps: a computer terminal obtains coordinate positions of N base stations, obtains a coordinate position and a center frequency of a calibration source, and sends a synchronization instruction of a clock and a trigger signal; the central station receives the synchronization instruction, generates N paths of trigger signals and N paths of clock signals, and respectively transmits the N paths of trigger signals and the N paths of clock signals to the N base stations; the computer terminal sets parameters and sends a positioning instruction to each base station, and each base station synchronously collects radiation source IQ data and records timestamps ...
