Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of shooting training, and in particular relates to a weapon shooting trajectory simulation method and device. Background Art
[0002] Currently, most common shooting training products are laser transmitters installed on actual guns and cannons. When a bullet is fired, the laser is emitted. Each participant or vehicle wears or has a laser receiver installed. When the laser is irradiated on the receiver and sensed by the receiver, it is determined that the person or vehicle is hit. Confrontation training through laser engagement can simulate the actual combat effect to a certain extent.
[0003] In fact, the trajectory of ammunition fired by guns is a curved trajectory and takes a certain amount of time to reach the target or target area from the launch end. In contrast, lasers travel in a straight line at the speed of light. At the same time, laser engagement can only simply determine whether it hits or roughly determine the hit location based on the position of the laser receiver.
[0004] With the increasing requirements for the realism of combat effects and the accuracy of damage in actual combat training, the original rough hit accuracy can no longer meet the needs. There is an urgent need for a method and device that can realize shooting trajectory simulation, which can reproduce the actual ammunition movement trajectory and flight time through ballistic fitting simulation for realistic combat confrontation training.
