Description

Technical Field

[0001] The present invention relates to the field of simulation technology, and in particular to an ultra-wideband fuze energy-type anti-interference performance simulation test system and method. Background Art

[0002] Fuze energy jamming uses broadband strong electromagnetic pulses or high-power continuous waves to radiate through the fuze antenna, or through holes, or directly act on components and circuits to interfere with the fuze, causing the fuze to malfunction or malfunction, or even cause permanent damage to the fuze. In actual applications, high-power microwave (HPM) weapons are often used to achieve energy jamming of fuzes, which are specifically divided into disposable high-power microwave bombs and reusable high-power microwave jammers.

[0003] At present, the simulation research on the interference of high-power microwave jammers on fuzes mainly studies the structural simulation of the front-door coupling and the back-door coupling of the fuze. This type of simulation only studies the effect of a certain device or some devices of the fuze under high-power microwave interference, lacks the effect of the fuze as a whole under the interference of high-power microwave jammers, and has certain limitations in the simulation research on the fuze's anti-energy interference. Therefore, the present invention takes ultra-wideband fuzes as the research object and proposes a fuze energy interference effectiveness test simulation system and method, which combines microwave darkroom test data with field test data, and then provides data support for the establishment of a high-power microwave jammer model in the simulation. Based on this simulation system, not only can the anti-interference performance of the fuze as a whole under the interference of high-power microwave jammers be studied, but also the demand for field live-fire shooting data can be reduced, saving manpower, material resources, and financial resources.

DETAILED DESCRIPTION

[0045] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0046] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0047] like Figure 1 As shown, an ultra-wideband fuze energy-type anti-interference effectiveness simulation test system includes a hypothetical simulation module, a geographical environment module, an equipment digital model module, a simulation situation display module and an anti-interference performance evaluation module. The hypothetical simulation module, the geographical environment module, the equipment digital model module, the simulation situation display module and the anti-interference performance evaluation module are integrated based on the VR-Forces simulation engine, and the human-computer interaction interface is developed based on the Qt architecture.

[0048] The hypothetical simulation module and the geographic environment module are mainly used to build simulation scenarios. The hypothetical simulation module uses the human-computer interaction interface, and the operator configures the model parameters according to the simulation requirements. The model parameters include the mortar attack direction, the type of mortar-mounted fuse, the number of mortar ready-to-fire projectiles, the mortar attack elevation angle, the initial velocity of the projectile, the HPM jammer interference direction, the HPM jammer power and repetition rate and other interference parameters.

[0049] The geographical environment module arranges the positions of equipment such as HPM jammers and mortars by dragging and dropping the mouse.

[0050] The equipment digital model module is the main part of the simulation system. Before the simulation starts, the simulation module sets the simulation data for the equipment digital model module.

[0051] After the simulation starts, the equipment digital model module changes dynamically according to the equipment model data transmitted by the VR-Forces simulation engine.

[0052] The present invention establishes an ultra-wideband fuze model, an energy-type interference model (HPM jammer model) and a key point defense mode confrontation model according to simulation requirements. The ultra-wideband fuze model displays the effects of normal proximity explosion, premature explosion or damage in the interference airspace of the HPM jammer, and the HPM jammer model interferes with the ultra-wideband fuze through electromagnetic pulses. The key point defense mode confrontation model provides theoretical support for the layout of simulation scenarios, and also provides a motion model for the ultra-wideband fuze in the simulation process, namely, an ideal parabolic trajectory model.

[0053] The simulation situation display module is used to receive the dynamic entity status and interactive information of the equipment model in the simulation process in real time, and display the simulation situation on the human-computer interaction interface. The two-dimensional situation can display the symbols of the HPM jammer, mortar, and tactical target. The symbols are displayed in the form of icons. It can also display the trajectory of the ultra-wideband fuze, the interference range of the HPM jammer, and the detonation effect of the ultra-wideband fuze under the action of the HPM jammer, such as: the ultra-wideband fuze near explosion displays a white circle. In short, the visualization effect of the HPM jammer interference process is displayed through the two-dimensional situation model.

[0054] The three-dimensional situation can display the three-dimensional effects of the HPM jammer, the target being attacked, etc., and can also display the airspace confrontation effect of the HPM jammer during the simulation. The electromagnetic pulse is displayed in the form of a beam, and the jammer confrontation situation display can be viewed in real time during the simulation, such as the distance between the projectiles, the effect of the projectiles, the parameter display of the jammer, etc.

[0055] After the simulation is completed, the anti-interference performance evaluation module collects statistics on the interference data of the HPM jammer on the ultra-wideband fuze by receiving the simulation results sent by the VR-Forces simulation engine, and displays the interference simulation results of the HPM jammer. Figure 2 shown.

[0056] The specific workflow is as follows:

[0057] Before the simulation begins, it is necessary to plan the simulation scene. First, load the established geographical environment model, then lay out the scene based on the geographical environment, and configure the scene parameters of the simulated HPM jammer, mortar, etc.

[0058] After the simulation starts, the parameters of the scenario configuration generate a simulation script file and send it to the simulation engine. After receiving the script file, the simulation engine loads and parses the script, and then starts running the simulation scenario. The simulation engine transmits the loaded and parsed equipment working parameters to the equipment digital model module. After receiving the parameters, the HPM jammer, ultra-wideband fuze, mortar and other equipment simulate the working mechanism and send their related working status to the simulation engine in real time. The simulation engine receives the real-time working status sent by the equipment digital model module and sends it to the simulation situation display module. The simulation situation display module displays the interference process in real time, such as the HPM jammer interference beam display, the ultra-wideband fuze ballistic trajectory display and the ammunition explosion effect display.

[0059] After the simulation is completed, the simulation engine sends the simulation results to the anti-interference performance evaluation module to display the interference results of the HPM jammer on the ultra-wideband fuze and evaluate the anti-interference performance of the fuze.

[0060] The present invention builds a key point defense mode confrontation model, an ultra-wideband fuze model and an HPM jammer model in the equipment digital model module;

[0061] The key defense mode confrontation model is used to describe combat scenarios, such as Figure 3 As shown in the figure, in this model, the HPM jammer is placed in front of the target and at an appropriate distance on both sides of the projectile trajectory; the beam direction is fixed and points to the direction of the projectile trajectory; the distance from the jammer to the target is much larger than the projectile killing radius; the fuze is loaded with mortars and the ballistic model adopts an ideal parabolic trajectory. Assume that the initial velocity of the projectile is The angle of incidence is , then the trajectory equation is:

[0062] ;

[0063] in , is the acceleration due to gravity; is the moving distance in the y-axis direction, z is the moving distance in the z-axis direction, and the projectile moves in the yoz plane.

[0064] The parameters of the ultra-wideband fuze model mainly include: fuze transmission power , fuze transmitting antenna gain , fuze transmitting antenna directivity function , Fuze receiving antenna gain , fuze receiving antenna directivity function and pulse width B.

[0065] The working principle of the ultra-wideband fuze model is mainly completed by three components, including the ultra-wideband fuze sensor component, the ultra-wideband fuze controller component and the ultra-wideband fuze actuator component. The ultra-wideband fuze sensor component is used to detect whether the fuze enters the beam range of the HPM jammer, calculates the power density at the fuze by detecting the distance from the jammer, and sends the calculation result to the ultra-wideband fuze controller component.

[0066] The UWB fuze controller component determines the current action state of the fuze according to the power density, determines the action mode of the HPM jammer on the fuze, and sends the relevant results to the UWB fuze actuator component.

[0067] The ultra-wideband fuze actuator assembly performs fuze action according to the fuze action mode sent by the ultra-wideband fuze controller assembly, including normal detonation (near explosion), damage (misfire), and premature explosion.

[0068] The specific workflow is as follows: after the simulation starts, the three components of the fuze are initialized first, and then it is determined whether the ultra-wideband fuze sensor component is working. When it is determined that the ultra-wideband fuze sensor component is working, all nodes in the scene are traversed to check whether there is an HPM jammer node. If an HPM jammer node is found, the working status is sent to the HPM jammer node. If no HPM jammer node is found, the fuze works normally when it is close to the landing point.

[0069] After receiving the working message from the ultra-wideband fuze sensor, the jammer node sends the jammer power and jammer antenna gain to the ultra-wideband fuze sensor component. The ultra-wideband fuze sensor component determines whether the ultra-wideband fuze has entered the HPM jammer beam based on this. If the ultra-wideband fuze has entered the jammer beam range, the power density is calculated and the power density value is sent to the ultra-wideband fuze controller component. The ultra-wideband fuze controller group derives the fuze action mode based on the power density, and sends the action mode to the ultra-wideband fuze actuator component. The ultra-wideband fuze actuator component acts according to the sent action mode. The workflow of the ultra-wideband fuze model is as follows: Figure 4 shown.

[0070] HPM jammer model parameters mainly include: transmission power , Transmitting antenna gain , Transmit repetition rate , carrier frequency and pulse width B. This paper only studies the effect of HPM jammer power on ultra-wideband fuze, and the repetition frequency, carrier frequency and pulse width are set to fixed values. In order to ensure that the ultra-wideband fuze can be within the interference range, the HPM jammer is always turned on during the simulation process, and the beam range of the HPM jammer model is set to be larger. The beam design is as follows: Figure 5 As shown, the beam is a pyramid as a whole; the maximum angle between the line connecting the HPM jammer and the fuze landing point and its side beam is , set as a constant; the angle between the line connecting the HPM jammer and the fuze landing point and its beam height is , set to a fixed value.

[0071] The HPM jammer model includes the HPM jammer sensor component and the HPM jammer actuator component. Since the HPM jammer node is always in working state during the simulation, the HPM jammer actuator component is always set to working mode, that is, the beam is emitted from the beginning of the simulation. The HPM jammer sensor component is used to receive the working state sent by the ultra-wideband fuze sensor component, and output the HPM jammer power value and antenna gain to the ultra-wideband fuze sensor component, so as to facilitate the calculation of power density by the ultra-wideband fuze sensor component.

[0072] During the simulation, the interference effect of the HPM jammer on the ultra-wideband fuze is randomly decided based on the power density of the fuze receiving end by querying the probability table, where the probability table is obtained from the microwave darkroom test data and the field experiment data according to the hierarchical analysis method. The probability table constructed in this embodiment is shown in Table 1.

[0073] Table 1 HPM jammer model empirical probability table

[0074] ;

[0075] This embodiment also provides a test and analysis method for an ultra-wideband fuze energy-type anti-interference performance simulation test system, comprising the following steps:

[0076] S1. Run the ultra-wideband fuze energy-type anti-interference effectiveness simulation test software, configure the simulation scene in general, click the simulation object in the entity object selection bar, and quickly deploy jammers, mortars, and strike targets by dragging the mouse;

[0077] Set the mortar attack direction and set the tactical plotting mark in the mortar attack direction. During the simulation, the mortar attacks the tactical plotting position and the HPM jammer model is arranged on the side of the tactical plotting. The simulation scenario is as follows: Figure 6As shown in the figure, a mortar model is arranged above the simulation scene map. The red diamond is the mortar, and the red " " is a tactical plot, and the blue rectangle is the HPM jammer.

[0078] S2. Set the mortar to carry an ultra-wideband fuze and set the mortar parameters to Figure 7 As shown, the firing round is 1 round, the number of ammunition carried is 100 rounds, the blasting height is 10m, the initial velocity of the shell is 200m / s and the mortar firing elevation angle is 50°.

[0079] S3, such as Figure 8 The HPM jammer parameters shown are: power of 90GW, carrier frequency of 3GHz, pulse width of 30ns and repetition rate of 20Hz.

[0080] S4. Save the simulation scene, start the simulation, and observe the real-time dynamics of the fuze. Fig. 9 As shown, the white circle indicates that the ultra-wideband fuze functions normally.

[0081] After the simulation is finished, check the information on the anti-interference performance evaluation display panel. The jammer's working status is as follows: Fig.10 As shown in the figure, the combat data statistics are as follows Fig.11 shown.

[0082] from Fig.10 You can see the HPM jammer parameters, ammunition status and the position of the fuze relative to the HPM jammer's main axis. Fig.11 The combat data statistics show that 6 rounds of fuzes were damaged, 15 rounds exploded prematurely, and 79 rounds of fuzes were working properly, with a damage rate of 6.00%, a premature explosion rate of 15.00%, and a normal rate of 79.00%. Compared with the fuze function test in which the HPM jammer was not deployed, it shows that the HPM jammer can be used normally.

[0083] Therefore, the present invention adopts the above-mentioned ultra-wideband fuze energy-type anti-interference effectiveness simulation test system and method, implements a distributed simulation architecture based on the VR-Forces simulation engine, and supports modular integrated simulation functions; establishes an ultra-wideband fuze model, an HPM jammer model and a confrontation interaction model, and provides an efficient and low-cost simulation platform for the confrontation research between high-power microwave weapons and ultra-wideband fuzes; the human-computer interaction interface supports flexible scene configuration, rapid equipment deployment and visualization of interference effects; through simulation instead of a large number of live-fire shooting experiments and field tests, it can effectively evaluate the effective anti-interference performance of ultra-wideband fuzes under specific interference conditions, reduce costs, risks and resource consumption, support multiple repeated tests, and provide theoretical support and technical verification tools for actual combat scenarios.

[0084] 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.
