[0004] In view of the application requirements of the visual dual-mode guidance, that is, the guidance in the data link + the end-of-infrared guidance of the aviation time-sensitive guided bomb hardware-in-the-loop simulation system, the pure digital simulation system and method used in the past can no longer meet and realize the required requirements. However, the currently disclosed visual simulation technology has the defects of single function, limited interface, and difficult secondary development. tracking and striking capabilities

Embodiment 1
[0076] The initial conditions for bombing are set as follows: bombing height 12000m, bombing speed: 0.95Ma, coordinates of the bombing point in the navigation system: north latitude 38.758°, east longitude 105.61°;
[0077] The design of the target motion parameters is as follows: set the target as a maneuvering target, and its motion is a variable-speed S-curve motion, and the coordinates of the initial position of the target point reported by the data link in the launch system are (65000,-332.123,0.0)m; The coordinates corresponding to the position in the navigation system are (39.3435°, 105.609°, 0.0m); the trajectory of the target is roughly the "S"-shaped curve motion of the cycle of "acceleration-uniform speed-deceleration"; the initial direction of the target movement is random, and its range It is north by east [0°, 180°], the initial movement speed is 0km / h, and the maximum speed is 20km / h.

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.
