Laser weapons, with their advantages such as high precision, high speed, and strong anti-interference ability, pose a serious threat to traditional equipment. For example, laser weapons can lock and destroy targets in a very short time, are almost unaffected by electromagnetic interference, and are relatively low in cost, making them suitable for large-scale deployment. However, this also means that traditional equipment faces unprecedented challenges when facing laser weapons.

[0051] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Example

[0053] like Figure 1 As shown in the figure, a simulation system for attack and defense confrontation of equipment under laser weapon attack includes a high-energy laser weapon design platform, which follows the divergence angle matching criterion, the highest power criterion in the barrel, the efficient coupling criterion and the platform adaptation criterion for attack, builds different types of laser weapon models, integrates megawatt-level high-beam quality light sources, optimizes long-range combat capabilities, ensures efficient damage effects, realizes compact and efficient design, and adapts to different platform requirements; the high-energy laser weapon design platform defines the functional composition, interface relationship and operation logic of different types of laser weapon models under combat business requirements, and adopts the unified modeling platform (UPDM) model for weapons and equipment. Each laser weapon model will select a suitable laser wavelength to improve the material coupling coefficient for a specific combat environment and task, while considering the atmospheric transmission characteristics and platform environmental adaptability. The schematic diagram of the high-energy laser weapon design platform is shown in the figure. Figure 2 shown.

[0054] The laser weapon early warning jamming platform is used for defense. It uses a high-repetition-rate laser as the core jamming source. It emits high-repetition-rate laser pulses to the laser seeker directly or through false target reflection to drown out the guidance signal. It integrates advanced coding and time gate technologies to adapt to the jamming requirements of different guidance signals. At the same time, the platform will have rapid response capabilities to reduce the impact of jamming reaction time on the jamming effect, and will be able to process a variety of signal styles, including finite-bit random periodic codes and precise frequency codes. In addition, the platform will avoid using integer repetition frequencies to reduce the uncertainty of the effective probability of jamming, and through a "one-to-many" jamming strategy, it will achieve simultaneous jamming of multiple laser-guided targets, thereby improving the overall jamming effect and battlefield adaptability. The schematic diagram of the laser weapon early warning jamming platform is shown below. Figure 3 shown.

[0055] The attack and defense simulation platform is used to build combat scenarios in combination with combat missions, configure different equipment models according to the laser weapon model, associate multiple equipment models with the operation of the laser weapon model, perform simulations based on the combat scenarios, and send the events generated in the combat to the high-energy laser weapon design platform to simulate the real battlefield environment and provide a realistic test scenario for the laser weapon model; the attack and defense simulation platform is implemented using the satellite toolkit STK physical model. The logic diagram of the attack and defense simulation platform is as follows: Figure 4 shown.

[0056] The joint simulation control platform is used to control the data and command interaction between the laser weapon model and the equipment model to achieve collaborative simulation; the interaction interface between the joint simulation control platform and the high-energy laser weapon design platform adopts a functional simulation interface that complies with the international joint simulation standard FMI; the simulation interaction relationship configuration table is used to define the configuration relationship between the laser weapon model and its equipment model to ensure the accuracy and efficiency of data interaction.

[0057] The high-energy laser damage assessment platform is used to calculate the effective range and damage effect of laser weapons and evaluate the damage of target materials. According to the combat parameters of laser weapons set by the high-energy laser weapon system, in the transmission model of tracking and aiming, the coordinates are calculated based on the dynamic motion parameters between the target and the laser weapon, thereby determining the real-time effective range. At the same time, combined with the set atmospheric transmission conditions, the specific parameters of the laser when it reaches the target can be calculated. The platform can also construct a calculation model of laser irradiated materials based on the characteristics of the target material, through which the relationship between the real-time thermal parameters and the damage threshold of the target material can be evaluated, thereby determining whether the target has been completely destroyed; such as Figure 5 As shown, the laser damage assessment factors of the high-energy laser damage assessment platform include laser weapon attributes, transmission influence factors and equipment target attributes.

[0066] S16. Comprehensively evaluate the results of the above models to obtain the final evaluation results. According to the results of the comprehensive evaluation model, design and construct the laser weapon model.

[0067] S2. Through the laser weapon early warning jamming platform, a high repetition rate laser is configured as the jamming source, and advanced coding and time gate technology is adopted to achieve effective jamming of the laser guidance signal.

[0074] S35. Optimizing and adjusting the parameters in the model according to the simulation test results;

[0075] S36. Verify the results of the optimized model. If it does not meet the requirements, return to S5. Continue to optimize and adjust the parameters. If it meets the requirements, obtain the equipment attack and defense confrontation model under the attack of laser weapons.

[0076] S4. The joint simulation control platform controls the data and command interaction between the laser weapon model and the equipment model according to the simulation interaction relationship configuration table, realizes collaborative simulation and enhances the credibility of the simulation.

[0077] S5. Through the high-energy laser damage assessment platform, the combat parameters of laser weapons are set, the dynamic interaction process between laser and target is simulated, the damage effect of laser on target is evaluated, and it is determined whether the target is destroyed, thereby providing a scientific basis for equipment research and development and tactical planning.

[0078] Therefore, the present invention adopts the above-mentioned system and method for simulating the attack and defense confrontation of equipment under the attack of laser weapons. By refining the combat concept into specific modes and processes, extracting and solidifying the rules of engagement and tactical behaviors, constructing a system architecture model, and clarifying the functions, interfaces and operating logic of the weapon system; supporting the coordinated interaction between the weapon system and the force model, enhancing the accuracy and reference value of the simulation simulation; at the same time, by dynamically verifying the system architecture model, the combat knowledge is verified and confirmed using the combat concept simulation environment, thereby ensuring the effectiveness of the model.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
