The invention discloses a visualization dual-mode guide aerial time sensitivity bomb semi-physical simulation system and method. The system comprises an airborne fire control system simulator, a target motion simulator, a trajectory and guide control simulator and a visualization simulator, wherein the trajectory and guide control simulator is respectively connected with the airborne fire control system simulator, the target motion simulator and the visualization simulator by a 1553B bus, an SBS optical network and an RS232 serial port. The method comprises the steps: the airborne fire control system simulator simulates a bomb dropping process and initial parameters of bomb dropping and transmits to the trajectory and guide control simulator by the 1553B bus; the target motion simulator simulates the motion information of a target and transmits to the trajectory and guide control simulator; in a simulation process, the trajectory and guide control simulator is connected with the visualization simulator by the RS232 serial port to display the flying and attacking process of a bomb in animation and curve diagram modes in real time. By adopting the system and the method, effective means are provided for the design and test of airarmament navigation and guide control rates, and the development period is shortened.
