The invention provides a photon-assisted annular distributed radar detection system and method. The system comprises a central station, a plurality of transmitting stations and a plurality of receiving stations, and the central station, the plurality of transmitting stations and the plurality of receiving stations are sequentially connected through optical fibers to form a ring network; two paths of multi-carrier optical carrier radar signals are generated in the central station, and the first path of multi-carrier optical carrier radar signals are sequentially transmitted in the first direction of the ring network; the second path of multi-carrier optical carrier radar signals are sequentially transmitted along a second direction of the ring network, and transmitting signals are obtained and transmitted in the plurality of transmitting stations based on the first path of multi-carrier optical carrier radar signals; and echo signals which are consistent with the carrier frequency of the transmitting signal ar
