Description

Simulation method and device of laser weapon, computer equipment and storage medium Technical Field The present application relates to the field of optical simulation technology, and in particular, but not limited to a method, apparatus, computer device, and storage medium for simulating a laser weapon. Background As a directional energy weapon, the laser weapon has a damage mechanism which is substantially different from that of the traditional kinetic energy or chemical energy weapon. The core is that the high-energy laser beam is continuously focused on a specific area of the target surface, so that the absorbed energy of the area in unit time exceeds the heat dissipation capacity of heat conduction, heat radiation and the like, thereby causing the temperature of the material to be rapidly increased, and melting, vaporization, structural failure or internal equipment damage occur. The physical process determines that laser damage has typical energy accumulation characteristics, namely, the laser light spot needs to be ensured to stably stay at a key part of a target for a certain time, so that the accumulated heat breaks through a thermal protection threshold of the target to form effective damage. The damage effect is not only dependent on the instantaneous power of the laser, but also closely related to factors such as the duration of irradiation, the properties of the target material, the attenuation of atmospheric transmission, etc. The existing scheme defaults to one shot to complete the damage assessment, and completely ignores the energy accumulation time required by the laser weapon to achieve effective damage. This is severely disjointed from the fundamental physical principle that laser damage requires continuous irradiation to build up heat. In the simulation, no matter whether the target is a small unmanned plane or a cruise missile with stronger protection, the same instant damage judgment is adopted, so that the difference of required irradiation time caused by the difference of the size, the material and the heat protection capability of different types of targets can not be reflected, and the reliability of the simulation result is lost. Existing schemes generally implicitly assume that a laser weapon possesses an unlimited energy supply and unlimited sustained firing capability, ignoring the critical performance limitations of a real laser weapon system. In practice, laser weapons are limited by power supply capacity, heat dissipation system efficiency, etc., and there is a limit to the maximum continuous exposure period of a single time beyond which heat dissipation must be suspended, while some charge/recharge time is required between shots or after energy is exhausted. The prior art does not model the practical operability constraints, so that the simulated laser weapon is represented as an ideal infinite fire unit, and the real combat rhythm and sustainable combat capability of the laser weapon cannot be reflected. In a real battlefield, rapid maneuvering of the target or tracking system performance limitations of the laser emitting platform may cause the laser spot to temporarily deviate from the target, resulting in interruption of the irradiation. The prior art does not establish decision criteria for such interrupts. More importantly, after interruption, the accumulated heat of the target cannot instantaneously disappear, and a natural cooling process exists. The existing scheme has no interruption judgment and no accumulation and attenuation model of thermal effect after interruption, so that the simulation can not reflect the common dynamic process of 'irradiation-interruption-continuous irradiation' and the influence of the common dynamic process on the final damage effect, and the simulation fidelity under the complex countermeasure scene is reduced. The existing scheme generally adopts a single and fixed damage calculation mode, and cannot be flexibly adapted to different targets from a micro unmanned plane to a large missile and the like. The user cannot preset or adjust the required irradiation time for a specific type of target according to tactical requirements. Meanwhile, the scheme only supports full-automatic shooting logic, lacks a manual irradiation control function, cannot meet simulation requirements of the commander for intervention under specific conditions, and has serious tactical flexibility. Disclosure of Invention In view of this, embodiments of the present application at least provide a method, an apparatus, a computer device, and a storage medium for simulating a laser weapon. The technical scheme of the embodiment of the application is realized as follows: In one aspect, an embodiment of the present application provides a method for simulating a laser weapon, the method including: Establishing continuous irradiation control logic of the laser weapon in a simulation deduction system, wherein the continuous irradiation control logic comprises an emission i
