Multi-point positioning system and method

The invention discloses a multipoint positioning system and method, the system comprises a data processing device and a plurality of signal conversion devices arranged outdoors, and each signal conversion device is in communication connection with the data processing device through an independent optical fiber; wherein the signal conversion equipment is used for receiving a radio frequency signal sent by a target, converting the radio frequency signal into an optical signal, and sending the optical signal to the data processing equipment through the optical fiber; the data processing device is used for converting the optical signals sent by the signal conversion devices into radio frequency signals at the same time and carrying out positioning calculation on the target according to the multiple radio frequency signals. The whole system uses homologous clocks for accurate positioning, inter-clock errors are reduced, the coverage distance is increased, and the positioning accuracy is improved. And moreover, the
