Abstract

The present disclosure relates to an airburst simulation system and method. The airburst simulation system includes a laser emitting unit to emit laser beam to an airburst aiming position, preset above a target hidden behind an obstacle, such that a warhead is airbursted to shoot the target, a laser detecting unit mounted onto the target to detect an arrival of the laser beam above the target, and a determining unit to measure a distance between the airburst aiming position and an arrival position of the laser detected by the laser detecting unit, and determine whether or not the target has been shot based on the distance. This allows for a simulated engagement using an airburst apparatus, with no harm to human bodies by virtue of the use of laser.

Claims

a laser range finder emitting laser beam having an optic axis, the laser range finder configured to measure a distance up to a target;

range varying buttons configured for adjusting a range;

a laser emitting unit configured for receiving information of the range and emitting a laser beam to an airburst aiming position, preset above a target hidden behind an obstacle, such that a warhead is airbursted to shoot the target, wherein an optic axis of the laser beam from the laser emitting unit is arranged to match the optic axis of a laser beam from the laser range finder;

a laser detecting unit mounted onto the target to detect an arrival of the laser beam above the target; and

a determining unit to measure a distance between the airburst aiming position and an arrival position of the laser detected by the laser detecting unit, and determine whether or not the target has been shot based on the distance.

3. The system of claim 2, wherein the laser emitting unit comprises:

a firing pin protruded by the trigger to press a simulated ammunition; and

a pressure sensor to sense pressure applied onto the simulated ammunition, and convert the sensed pressure into a signal to transfer to the laser emitting unit.

4. The system of claim 3, wherein the laser emitting unit further comprises a firing noise generator to generate noise upon emitting the laser beam.

5. The system of claim 2, wherein the laser emitting unit comprises:

a blank cartridge fired by the trigger; and

7. The system of claim 1, wherein the laser detecting unit comprises:

first and second cameras disposed with being spaced apart from each other to photograph the laser beam, respectively, at the spaced positions; and

a posture sensing unit to measure respective angles that the first and second cameras face the laser.

8. The system of claim 1, wherein the determining unit measures the distance between the airburst aiming position and the arrival position of the detected laser, to determine whether or not the target has been shot based on the measured distance and a preset reference distance.

9. The system of claim 8, wherein the determining unit comprises a display unit to output at least one of an image and a sound to indicate whether or not the target has been shot.

10. The system of claim 1, wherein when the laser emitting unit emits a plurality of laser beams, the determining unit determines which laser beam of the plurality of laser beams has shot the target, by comparison between a time point of sensing the arrival of the laser beam and a time point of emitting the laser beam, comparison between coordinates of a position of the target and coordinates of the airburst aiming position, and comparison between a directional vector of the emitted laser beam and a directional vector of the laser beam detected by the laser detecting unit.
