Description

Technical Field

[0001] The present invention belongs to the technical field of computer vision, and particularly relates to a simulation method for a multi-purpose electromagnetic pulse simulator. Background Art

[0002] Electromagnetic pulse (EMP) has continuously attracted the attention of many scholars due to its extremely strong destructive effect on electronic devices. Especially in the current era of rapid development of electronic information science, it is particularly important to test, assess, and accept the anti-EMP interference capabilities of electronic products, weapons and equipment, etc. Due to the complex characteristics of the EMP environment, EMP tests basically require artificial simulation of the EMP environment. Most of the EMP test equipment studied at home and abroad can only generate single-polarized pulse waves. In actual tests, some equipment needs to be tested for specific polarized pulses. The multi-purpose electromagnetic pulse simulator is a combined simulator. It can form electromagnetic pulse simulators for different purposes with a high-voltage pulse source and two types of electric field irradiators. One is a movable simulator for radiating horizontally polarized waves; the other is a movable simulator for radiating vertically polarized waves. This multi-purpose EMP simulator can generate pulse waves in two polarization modes, horizontal and vertical. Moreover, this simulator is convenient and flexible to use and can provide EMP assessment tests for various devices. However, due to the complexity of EMP test equipment, the equipment is often expensive, which will greatly increase the costs of enterprises. In recent years, due to the rapid development of computer technology, many electromagnetic simulation software has emerged. Moreover, with the iterative update of the software, the simulation results of the software are closer to the actual situation, and the simulation method is simple and easy to operate, eliminating the high costs. Therefore, if a simulation method for a multi-functional EMP simulator is given by simulation means, the EMP protection capabilities of the equipment can be effectively analyzed and predicted.

[0003] Authorized patent CN97100570.2 discloses a multi-functional electromagnetic pulse simulator with three-source convergence. The electromagnetic pulse generated at one time has the properties of lightning, nuclear power, and other electromagnetic pulses. It can be used to simulate the harm degree of these electromagnetic pulse sources to electronic and electrical systems to seek protection and reinforcement methods. This technology utilizes the three functions of the inductor L for energy storage, voltage boost, and generation of near-field induction fields, and uses a simple explosive conductor break switch Sop, and utilizes the electromagnetic pulses generated by the discharge of each switch, so that a wide-spectrum and high-field-strength electromagnetic pulse can be obtained in one discharge with a simple method and low cost. However, the multi-functional electromagnetic pulse simulator in this technology can only generate single-polarized waves and cannot meet the requirements when there are specific requirements for the polarization of electromagnetic pulse waves.

[0004] The invention patent CN202010354240.7 discloses a multi-functional electromagnetic pulse simulation experimental system with a shared antenna, which includes a control system, an antenna system, a measurement system, and multiple pulse power sources. Each pulse power source is a Marx-type pulse power source with a programmable controller built therein. The characteristics are as follows: The switch control circuits of the multiple pulse power sources are respectively connected to the control system, and the control system controls the switches of each pulse power source through the built-in pulse power source switching control circuit. The antenna system is arranged on one side of the output ends of the multiple pulse power sources, and the antenna system is switchably connected among the multiple pulse power sources, thereby forming an electromagnetic pulse simulator for simulating different waveforms. The measurement system includes a pulse power source parameter monitoring system, an electric field measurement system, and a data automatic acquisition and processing system. It can simulate multiple electromagnetic pulses with one antenna system matched on one site, saving the test cost. However, in this technology, a multi-functional electromagnetic pulse simulation experimental system with a shared antenna can only generate a single polarization wave and cannot meet the requirements when there are specific requirements for the polarization of electromagnetic pulse waves.

[0059] In order to enable those skilled in the art to better understand the solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

[0060] Embodiment

[0061] The multi - purpose EMP simulator is assembled by a pulse source and a movable electric - field irradiator. The pulse source and the movable electric - field irradiator are assembled into a movable EMP simulator with two polarization modes, vertical and horizontal, and finally a multi - purpose EMP simulator is obtained.

[0062] The simulation of the multi - purpose EMP simulator in this embodiment mainly follows the requirements for EMP simulators in GJB1389A - 2005 and GJB8848 - 2016 standards:

[0063] A. The spatial incident field is a double - exponential wave;

[0064] B. Peak field strength: ≥50 kV / m; The EMP environment in GJB1389A - 2005 is as Figure 2 shown;

[0065] C. Rise time: 2.5 ns ± 0.5 ns;

[0066] D. Full width at half maximum: 23 ns ± 5 ns;

[0067] As Figure 1 shown, this embodiment provides a simulation method for a multi - purpose electromagnetic pulse simulator, including the following steps:

[0068] S1. Construct a pulse - source simulation model;

[0069] S2. Construct a vertically polarized movable EMP simulator and a horizontally polarized movable EMP simulator;

[0070] S3. Calculate the radiated electric field of the simulator;

[0071] S4. Compare the calculated radiated electric field with the standard waveform. If it is outside the error range, adjust the voltage excitation source or optimize the simulation model until the error range meets the standard requirements.

[0072] Furthermore, in step S1, the specific construction of the pulse source simulation model is as follows:

[0073] Set discrete ports at the excitation end and finally add a voltage excitation source;

[0074] The voltage excitation source is a double exponential wave, that is:

[0075] V(t) = V 0 (e -αt -e -βt )

[0076] In the formula: α = 1.5×10 6 s -1 ; β = 2.6×10 8 s -1 ; The peak value V p of V(t) is approximately 50 kV.

[0077] The pulse source simulation model is as Figure 3 shown.

[0078] Furthermore, in step S2, the specific construction of the vertically polarized movable EMP simulator is as follows:

[0079] As Figure 4 shown is a movable vertically polarized EMP simulator, which is assembled by a pulse source and a movable electric field irradiator. The configuration of the electric field irradiator and the terminal matching load is as Figure 4 shown. Its electric field irradiator adopts a cone-plate form, which consists of a triangular cone plate and a ground grid. In fact, both the cone plate and the ground grid are wire grids, and the wire grid ends are connected to two resistive loads. When the pulse source is placed on the ground and the ground grid is laid on the ground, it can radiate vertically polarized waves to the test object on the ground.

[0080] First, according to Figure 4 give the simulation model of the electric field irradiator, as Figure 5 shown; secondly, assemble the pulse source simulation model and the movable electric field irradiator model into a movable vertically polarized EMP simulator, as Figure 6 shown.

[0081] Furthermore, in step S2, the specific construction of the horizontally polarized movable EMP simulator is as follows:

[0082] As shown Figure 7 in the figure is a movable horizontally polarized EMP simulator, which is assembled by a pulse source and a movable electric field irradiator. When the pulse source is placed on an electro-hydraulic lifting platform, the ground grid extends as the pulse source rises and reaches a state perpendicular to the ground. The conical plate is pulled open at an angle with the ground grid, and at this time, a movable horizontally polarized EMP simulator is formed, and a horizontally polarized wave can be radiated to the ground.

[0083] First, according to Figure 7 the given simulation model of the electric field irradiator is presented, as shown Figure 8 in the figure; secondly, the simulation model of the pulse source and the model of the movable electric field irradiator are assembled into a movable vertically polarized EMP simulator, as shown Figure 9 in the figure.

[0084] Furthermore, as shown Figure 10 in the figure, in step S3, the specific calculation of the radiation electric field of the simulator is as follows:

[0085] Create a discrete port at the pulse source of the simulator for feeding;

[0086] Set the parameters of the simulation frequency band, background material, and boundary conditions;

[0087] Set an electric field probe at the terminal of the irradiator;

[0088] Calculate the radiation electric field of the simulator at a given frequency point.

[0089] The specific calculation process is as follows: Click New Excitation Signal in the Simulation option to create a voltage excitation source signal, where Signal type is selected as Double exponential (double exponential wave), and then the signal settings are carried out in Signal settings. The set parameters include Ttotal (signal period), Trise (rise time), Amplitude (peak field strength), Tfall (fall time). The parameter settings should ensure that the radiation field waveform of the pulse simulator at a specific position meets the standard requirements. Click Plane Wave in the Simulation option, set Type to Linear in Polarization settings (polarization settings), set the electric field to vertical and horizontal polarization respectively in Propagation and electric field settings, and finally set an electric field probe at the terminal of the irradiator respectively, as shown Figure 11 、 Figure 12 in the figure.

[0090] Further, in step S4, the calculated radiation electric field is compared with the standard waveform, and the simulation model is iteratively optimized, specifically as follows:

[0091] Since the electromagnetic wave radiated by the voltage excitation source attenuates during propagation, it is necessary to compare the calculated radiation electric field with the standard waveform. The radiation electric field in a specific area of each simulator is compared with the standard waveform, and the pulse parameters include the peak field strength, the rising edge, and the full width at half maximum.

[0092] Iteratively optimize the simulation model: When the radiation field amplitude of the pulse simulator is less than the standard value, the radiation field amplitude of the pulse simulator can meet the standard value through two measures. One is to appropriately increase the peak value of the voltage excitation source. In the module for setting the excitation source in the simulation software, the amplitude of the excitation source can be set separately. The other is that if the radiation field amplitude of the simulator is still less than the standard value after increasing the peak value of the voltage excitation source, the length of the ground grid of the pulse simulator can be appropriately reduced. This operation process can be implemented in the model design module of the simulation software.

[0093] In this embodiment, the established simulation models of the vertical and horizontal polarization EMP simulators are simulated, and by adjusting the voltage excitation source or iteratively optimizing the simulation model, the electric field waveforms of the EMP simulators in the vertical and horizontal polarization modes at specific positions are obtained as Figure 13 、 Figure 14 shown. It can be seen from the figure that the radiation field amplitudes of the EMP pulse simulators in the vertical and horizontal polarization modes both meet the standard requirements, and the rising edges and full widths at half maximum of the electric field waveforms also comply with the standard regulations. Therefore, the vertical and horizontal polarization EMP simulators simulated by the present invention meet the requirements for EMP simulators in GJB1389A-2005 and GJB8848-2016 standards.

[0094] As Figure 15 shown, in another embodiment of the present application, a simulation system for a multi-purpose electromagnetic pulse simulator is provided.

[0098] The comparison and optimization module is used to compare the calculated radiation electric field with the standard waveform. If it is outside the error range, the voltage excitation source is adjusted or the simulation model is optimized until the error range meets the standard requirements.
