[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0052] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0053] Please see Figure 1The specific embodiment shown in this invention discloses a simulation verification method for the countermeasure function level of an air defense missile weapon system, comprising the following steps:

[0054] S1, construct the combat environment and set simulation parameters;

[0055] Step S1 includes: developing a combat situation plan, constructing the operational posture of the air defense missile weapon system based on the hypothetical scenario, loading 3D imagery maps and digital elevation maps, setting the initial position parameters, initial attitude parameters, and initial velocity parameters of radar, jamming equipment platforms, and target platforms, and displaying the deployment posture of each combat equipment platform on the electronic map using a 3D model; setting the motion trajectory of the mobile platform by loading track files, selecting map points, and setting geometric flight paths; setting the RCS attribute of the target platform; and setting the working mode and working parameters of the electronic information equipment.

[0056] Specifically, such as Figure 2 As shown, the air defense missile weapon system countermeasure function level simulation system mainly consists of subsystems such as battle scenario, simulation and deduction, model and calculation, integrated display, and database.

[0057] The combat scenario planning subsystem is used to construct the combat platforms, weapons, equipment, targets, and combat environment of both sides in a battle or confrontation on an electronic map. It mainly includes combat scenario management, platform attribute editing, platform trajectory editing, equipment parameter editing, and environment editing. Combat scenario management includes operations such as creating, opening, modifying, copying, closing, deleting, saving, and exporting combat scenarios.

[0058] Platform attribute / track editing, equipment parameter editing, and environment editing allow users to set combat platform tracks, target platform RCS, and add or delete air defense missiles, radars, seekers, command lines, command and control communications, radio fuses, reconnaissance jamming, and other electronic equipment within the opened combat scenario. Users can also edit and revise platform parameters, equipment parameters, and atmospheric attenuation parameters.

[0059] When building or editing battle situations, platform parameters, equipment parameters, and environment parameters can be configured by calling the database, and data can also be stored in the database.

[0060] The simulation and deduction subsystem uses the simulation timeline as a benchmark and performs dynamic simulations and calculations of combat scenarios based on the hypothetical scenarios, equipment operating modes, and operating parameters. It provides simulation settings, simulation control, simulation driving, and intermediate layer services.

[0061] Simulation settings refer to the settings of simulation parameters such as simulation duration, step size, and speed.

[0062] Simulation control is the control center of the simulation system, which performs tasks such as loading the situation, managing the simulation process, managing synchronization, facilitating information exchange between simulation subsystems or modules, and starting, pausing, continuing, and ending the simulation.

[0063] The simulation driver supports time-triggered, event-triggered (such as signal-to-noise ratio, signal-to-interference ratio, interference-to-noise ratio, measurement accuracy)-triggered, human-in-the-loop driven, and scheduling according to a predetermined strategy.

[0064] Middleware services are middleware components that provide services to all views, used for M (data model) and V (view) separation.

[0065] The model and computation subsystem provides spatial and electromagnetic models of the dynamic interaction between combat platforms, equipment, targets, and the environment. Specifically, it includes data models of combat situation, platforms, flight paths, equipment, and equipment networks; spatial relationship calculations for combat platform equipment at each simulation cycle; and calculations of performance parameters such as signal-to-noise ratio, signal-to-interference ratio, interference-to-noise ratio, effective range, and measurement accuracy for electronic information equipment such as radars, active / semi-active seekers, command lines, command and control communications, and radio fuses. The computational models can exist in the model and computation library in the form of algorithms, data, or files. During simulation, the corresponding data or calculations are retrieved from the model and computation library.

[0066] The integrated display subsystem is based on two-dimensional / three-dimensional digital maps to realize the three-dimensional situation display of combat scenarios and simulations, as well as the graphical display of simulation data. It includes a map control and display module, a three-dimensional situation display module, and a performance curve display module.

[0067] The map manipulation and display module includes loading and displaying satellite imagery, vector maps, and digital elevation data, as well as controlling map zooming, panning, rotation, positioning, view reset, profile analysis, model picking, geographic information extraction, and layer settings.

[0068] The 3D situational awareness display, based on digital maps and 3D models, shows operational situational information such as geographical environment, troop deployment, and movement trajectories, as well as electromagnetic situational information such as antenna beam scanning, radar power maps, and reconnaissance and jamming areas of reconnaissance and jamming aircraft. It can also display countermeasures and strike effects, specifically including the movement attitude and trajectory of aircraft, ships, and missiles, communication link displays, radar power displays, and explosion effects displays. The 3D situational awareness display supports viewpoint selection, defaulting to a free viewpoint. It can bind the viewpoint to the selected 3D model object, enabling global, radar, and other field-of-view selections, and displaying real-time changes in the target observation field of view.

[0069] Performance curve display shows the variation of various performance parameters (such as signal-to-noise ratio, signal-to-interference ratio, etc.) of radar, seeker, command line, radio fuse, and command and control communication over time and distance in the form of graphs and curves.

[0070] The database subsystem is a public resource library that provides basic models and data for the development of simulation software and system operation. It mainly includes a situation database, parameter database, model database, geographic information database, and simulation result database.

[0071] Specifically, in the simulation preparation phase, the combat situation planning subsystem completes the combat situation planning and design, constructing the operational posture of the air defense missile weapon system according to the hypothetical scenario. First, it completes the loading, display, and control of 3D image maps and digital elevation maps. Second, it sets the initial positions (longitude, latitude, altitude, relative ground altitude), initial attitudes (heading angle, yaw angle, pitch angle, roll angle), and initial speeds of the radar, jamming equipment platforms, and target platforms, and displays the deployment posture of each combat equipment platform on the electronic map using a 3D model; the air defense missile is mounted as a sub-platform on the guidance radar vehicle. Third, it mounts electronic information equipment such as radar, seeker, command and control communication, and reconnaissance jamming aircraft onto their respective loading platforms, with active / semi-active seekers, command lines (onboard), and radio fuses mounted on the air defense missiles. Then, the motion trajectory of mobile platforms such as aircraft is set by loading trajectory files, selecting points on the map, and setting geometric flight paths. For platform flight paths generated by selecting points on the map, parameters such as longitude, latitude, altitude, and speed of each path point can be manually modified to set the platform to fly at constant speed / variable speed and constant altitude / variable altitude. By setting geometric parameters, circular, arc-shaped, elliptical, runway-shaped, and figure-eight-shaped flight paths can be generated. Ballistic missile trajectories can be set by selecting missile impact points (longitude, latitude, and altitude). Next, the average RCS, fluctuation type (Swerling0-Swerling4), and oscillation amplitude of each target platform are set, or the RCS attributes (frequency, polarization, azimuth, elevation, RCS value, etc.) of the target platform are set by loading RCS data files. Finally, the operating modes, operating parameters, and electromagnetic wave transmission attenuation of electronic information equipment such as radar, active radar seekers, semi-active radar seekers, command lines, radio fuses, command and control communications, and jammers are set, respectively, as follows: Figures 3-10 As shown.

[0072] S2, based on the simulation parameters, execute the simulation and calculate the simulation data to obtain data information;

[0073] The S2 step includes: platform position and attitude calculation, relative distance and angle calculation between platforms, echo signal power calculation / receiver internal noise calculation / interference signal power calculation, signal-to-noise ratio calculation / signal-to-interference ratio calculation / dryness ratio calculation, angle measurement accuracy calculation / range measurement accuracy calculation / velocity measurement accuracy calculation, and detection distance calculation / tracking distance calculation, in order to obtain data information.

[0074] Specifically, during the simulation phase, the system loads combat information and distributes it to the corresponding simulation nodes. Each simulation node receives the combat information, performs parameter parsing and binding, completes the corresponding initialization work, and reports back to the simulation unit. The system performs simulation calculations according to the combat situation: calculating the positions and attitudes of platforms such as radar, jammers, and targets; switching the working modes and parameters of radar and jammers as needed; calculating the radar's signal-to-noise ratio, signal-to-interference ratio, interference-to-noise ratio, detection range, and tracking performance; and calculating and displaying the battlefield situation and electromagnetic situation. When an enemy target enters the combat airspace of the air defense missile weapon system and meets the missile launch conditions, the missile launch is automatically or manually set, and the onboard command line, active / semi-active seeker, radio fuse, and other electronic equipment are activated sequentially according to the set trigger conditions. The system calculates the signal-to-noise ratio and signal-to-interference ratio of each onboard electronic equipment. When the system termination conditions are met, the model calculation is stopped, and a simulation stop command is sent to each simulation node to stop the simulation experiment. If an abnormal situation occurs during the simulation and a simulation interruption is required, the system sends a simulation interruption command, and each node forcibly interrupts the simulation.

[0075] S3 displays and collects data information;

[0076] The data display includes both three-dimensional situational awareness and two-dimensional data display. The three-dimensional situational awareness display includes: geographic environment display, platform attitude display, platform trajectory display, antenna beam scan display, radar power map display, communication link display, reconnaissance and jamming range display, and strike effect display. The two-dimensional data display includes: radar performance display, active seeker performance display, semi-active seeker performance display, command line performance display, radio fuse performance display, command and control communication performance display, reconnaissance and jamming performance display, and field strength monitoring display.

[0077] S4, determine whether the simulation is complete; if the simulation is not complete, return to step S2.

[0078] S5. If the simulation is complete, upload the collected data to the simulation results database.

[0079] S6, the simulation results database outputs a simulation verification report.

[0080] In step S6, the output simulation verification report includes combat scenario data, air defense missile weapon system detection performance, and anti-jamming performance test data.
