The invention relates to the technical field of radar data processing and discloses an omnidirectional radar data processing method and system. The method comprises the following steps: determining a grid where a target locates; carrying out association with targets in the adjacent grids; carrying out polar coordinate Kalman filtering; carrying out rectangular coordinate Kalman filtering by utilizing the result of the previous stage of filtering; and carrying out target track management. According to the method and system, grid division is carried out on radar detection airspace, and neighborhood space association is carried out, so that calculation amount can be effectively reduced, and running speed of the system is improved; and a multi-step multistage Kalman filtering model is used, so that advantages of the two can be effectively utilized, and measurement accuracy of the whole radar system is improved.
