Description

Technical Field

[0001] This application relates to the field of electromagnetic signal processing technology, and in particular to a distributed reconnaissance and jamming equipment testing system and method. Background Technology

[0002] The distributed reconnaissance and jamming equipment testing subsystem aims to construct a highly realistic hardware-in-the-loop (HIL) test and verification system within a laboratory, simulating the electromagnetic environment and combat scenarios of actual battlefields. HIL systems play a crucial role in the testing and verification of modern military equipment, capable of reproducing complex electromagnetic interference and countermeasures in a controlled environment, providing fundamental data for equipment performance evaluation. However, traditional HIL systems typically rely on fixed shielded anechoic chambers or open areas, which presents certain limitations. First, traditional testing environments are usually static, making it difficult to reproduce the dynamic and complex characteristics of electromagnetic environments. For example, the characteristics of dynamic signals such as frequency-hopping communication, pulse radar, and multipath interference are difficult to simulate in traditional environments, resulting in significant deviations between test results and actual combat conditions. Second, traditional testing methods often lack flexibility, unable to adjust signal density, intensity, and spatial distribution, thus limiting the adaptability testing of equipment under various complex scenarios. Due to these limitations, traditional testing systems may not fully reflect the equipment's performance in actual combat during some key tests, thereby affecting equipment performance evaluation and improvement.

[0021] To enable those skilled in the art to better understand the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present disclosure.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] Electromagnetic jamming equipment is primarily used to actively interfere with enemy electronic systems, including radar and communication systems, to reduce their detection and communication capabilities. The main types of jamming include noise jamming, deception jamming, and communication jamming.

[0024] Example 1 This application provides a distributed reconnaissance and jamming equipment testing system, whose networking method is as follows: Figure 1 As shown, it includes: The test environment includes the device under test (DUT) and the interfering device in different shielded environments. The DUT and the interfering device receive signals from the test environment and / or send signals to the test environment via antennas. Reconnaissance equipment, configured to monitor electromagnetic signals in the test environment to obtain reconnaissance data; The test platform is configured to control the device under test and the jamming device according to the test plan, and to obtain test results after processing the reconnaissance data acquired by the reconnaissance device.

[0025] A test method for distributed reconnaissance and jamming equipment applied to the above system, the method including: Configure the device under test and the corresponding interference device in the test environment according to the configuration scheme of the target under test and the interference device. The testing platform obtains the test plan based on the operating parameters of the target under test and the corresponding interference device. According to the test plan, the test platform controls the device under test and the jamming device to simulate the target under test and the corresponding jamming device in the test environment. The testing platform obtains reconnaissance data of the testing environment through reconnaissance equipment, and obtains test results based on the reconnaissance data.

[0026] Specifically, the testing environment and reconnaissance equipment are set up in a larger electromagnetic shielding environment, which is defined as the first shielding environment, such as an electromagnetic shielding room. The testing platform can be set up in the first shielding environment or outside the first shielding environment, and communicate with the equipment in the first shielding environment through shielded cables.

[0027] The device under test and the interfering device can be a signal generator, a vector signal generator, or other EMC-specific test equipment.

[0028] The test platform includes at least a computer device connected to the reconnaissance equipment, which is used to acquire reconnaissance data from the reconnaissance equipment when the distributed reconnaissance jamming equipment test system is in operation.

[0029] Optionally, the test platform can communicate with the device under test (DUT), jamming device, and reconnaissance device via a wired connection to control them and acquire reconnaissance data from the reconnaissance device. In some cases, the test platform can also communicate with the DUT and jamming device wirelessly to control them. This is suitable when the control program is sent to the DUT and jamming device wirelessly before the test begins, and the DUT and jamming device only need to execute the pre-received control program during the test.

[0030] When testing is required, the device under test (DUT) and the jamming device are configured in the electromagnetic shielding environment according to the target under test (DUT) to be simulated and the jamming device used to interfere with the detection of the DUT. Generally, the DUT corresponds to the DUT and the jamming device corresponds to the jamming device. The DUT and the jamming device are set in independent shielding environments, which are defined as the second shielding environment. Signals are transmitted and / or received only through antennas. Since the DUT and the jamming device are often large and far away, they cannot be directly reproduced in the first shielding environment. Based on the above method, by configuring amplifiers and attenuators for the antennas, the electromagnetic environment of the DUT can be simulated in the first shielding environment. Then, the first shielding environment is detected by the detection device to obtain detection data. The test platform compares the detection data with the working data of the DUT or the DUT and obtains the test results based on the comparison results.

[0031] This embodiment provides a system and method for testing electronic equipment using a movable shielded test box, which at least solves the problem that traditional test systems may not be able to fully reflect the performance of equipment in actual combat in some key tests, thus affecting the performance evaluation and improvement of equipment.

[0032] Example 2 like Figure 2 and Figure 3 As shown, this embodiment, based on Embodiment 1, provides a distributed reconnaissance and jamming device testing system, comprising: The test environment includes the device under test (DUT) and the interfering device in different shielded environments. The DUT and the interfering device receive signals from the test environment and / or send signals to the test environment via antennas. Reconnaissance equipment, configured to monitor electromagnetic signals in the test environment to obtain reconnaissance data; The test platform is configured to control the device under test and the jamming device according to the test plan, and to obtain test results after processing the reconnaissance data acquired by the reconnaissance device.

[0033] Optionally, the antenna is configured as at least one of the following: The first receiving antenna is configured to receive signals transmitted by the device under test via a wired connection and send the signals to the shielded environment corresponding to the interfering device. The first transmitting antenna is configured to receive signals transmitted by the jamming device via a wired connection and transmit the signals to the test environment outside the shielded environment; The second receiving antenna is configured to receive signals from the test environment outside the shielded environment and transmit them to the device under test in the shielded environment via a wired connection. The second transmitting antenna is configured to receive signals transmitted by the device under test via a wired connection and transmit the signals to the test environment outside the shielded environment.

[0034] Specifically, jamming devices generally operate either according to preset parameters or adapt to the electromagnetic environment surrounding the detected target. Operating based on this adaptability requires detecting the external electromagnetic environment via an antenna. To simulate real-world operation, during testing, the first receiving antenna is configured to receive signals transmitted from the device under test (DUT) via a wired connection and transmit these signals to the shielded environment corresponding to the jamming device. This allows the jamming device to simulate the operation of the jamming device based on the detected electromagnetic environment surrounding the target. Furthermore, the first receiving antenna can also be configured to receive electromagnetic signals near the DUT within the first shielded environment and transmit these signals to the shielded environment corresponding to the jamming device.

[0035] Specifically, the first transmitting antenna is configured to receive signals transmitted by the jamming device via a wired connection and send the signals to a test environment outside the shielded environment. The jamming device operates according to a preset working mode and sends jamming signals to the first shielded environment through the first transmitting antenna, so as to realize the jamming device's simulation of the jamming device's transmitted signals.

[0036] Specifically, the second receiving antenna is configured to receive signals from the test environment outside the shielded environment and transmit them to the device under test (DUT) in the shielded environment via a wired connection. In some test schemes, signals can be received from the test environment outside the shielded environment via the second receiving antenna and transmitted to the DUT in the shielded environment via a wired connection. In this case, the DUT is also configured as a reconnaissance device, and there is no need to set up a separate reconnaissance device.

[0037] Specifically, the second transmitting antenna is configured to receive signals transmitted by the device under test (DUT) via a wired connection and transmit the signals to the test environment outside the shielded environment. The DUT operates according to a preset working mode and transmits interference signals to the first shielded environment through the second transmitting antenna, thereby simulating the signal transmitted by the DUT to the target under test.

[0038] Optionally, the first receiving antenna is also configured to receive signals transmitted by other jamming devices via a wired connection and send the signals to the shielded environment corresponding to the jamming devices.

[0039] Specifically, in order to better simulate the working mode of the jamming device based on the electromagnetic environment around the detected target, the first receiving antenna is configured to simultaneously receive signals transmitted by the target and other jamming devices via a wired connection and send the signals to the shielded environment corresponding to the jamming device, which can more accurately simulate the electromagnetic environment near the target as detected by the jamming device.

[0040] Optionally, an attenuator and / or an amplifier are also provided on the first receiving antenna and / or the first transmitting antenna, and the test platform is further configured to control the attenuator and / or the amplifier according to the test plan.

[0041] Specifically, this solution uses attenuators and / or amplifiers to simulate the operating parameters and operating environment of the target under test and the jamming device. Since the jamming device or the target under test generally has high power and strong signal, the jamming device and the device under test need amplifiers to simulate the operating parameters of the target under test and the jamming device. Since the distance between the target under test and the jamming device and between different jamming devices is large, attenuators are needed to simulate the signal loss caused by distance.

[0042] Optionally, the device under test and the interfering device are placed in different shielded test chambers to be in different shielded environments; The first receiving antenna is set on the inner wall of the shielded test box. It receives signals transmitted by other devices through the interface on the outer wall of the shielded test box and sends the signals to the shielded environment corresponding to the interfering device. The first transmitting antenna is installed on the outer wall of the shielded test box. It receives signals transmitted by interference devices inside the shielded test box via cables and sends the signals to the test environment outside the shielded test box. The second receiving antenna is installed on the outer wall of the shielded test chamber to receive signals transmitted by other devices in the test environment and transmit the signals to the device under test in the shielded environment via a wired connection. The second transmitting antenna is installed on the outer wall of the shielded test chamber. It receives signals transmitted by the device under test inside the shielded test chamber via a cable and transmits the signals to the test environment outside the shielded test chamber.

[0043] Specifically, the shielded test chamber is a crucial piece of equipment in this testing system, used to construct the second shielded environment within the system. The shielding performance of the test chamber directly impacts the system testing; therefore, the shielding design of the chamber was strengthened during the design phase. The shielded test chamber consists of a main frame, shielding shell, walls, absorbing material, shielding door, ventilation window, and signal enclosure. The main frame and shielding shell are welded together, and the shielding door and signal enclosure are designed on the same side. A honeycomb waveguide ventilation window is designed on the back.

[0044] Specifically, the inner wall of the shielded test chamber is covered with absorbing cones, with a thickness greater than 100mm, covering the 10MHz~18GHz frequency band. When operating at frequencies of 2~18GHz, the reflection level is better than 30dB, i.e., the absorption efficiency is ≥99.9%. Material seams overlap by ≥20mm, and curved absorbers are used at corners to reduce reflection. The surface resistivity of the ground is ≤10 Ω. 6 An Ω-shaped conductive ground plane is used, and a ferrite absorbing sheet with a thickness of at least 1.5 mm is attached between the antenna and the device under test to suppress surface wave interference.

[0045] Optionally, the shielded test chamber is set up on a mobile platform; The mobile platform is configured to move within the test environment in response to receiving control commands from the test platform so that the distribution of the device under test and interfering devices conforms to the requirements of the test plan.

[0046] Specifically, in order to simulate the interference effect of the jamming device in different directions, the shielded test box is set on the mobile platform. The mobile platform carrying the jamming device can rotate around the mobile platform carrying the device under test to simulate the jamming device in different directions of the target under test.

[0047] This embodiment provides a system for testing electronic equipment using a movable shielded test box, which further solves the problem that traditional test systems may not be able to fully reflect the performance of equipment in actual combat in some key tests, thus affecting the performance evaluation and improvement of equipment.

[0048] Example 3 This embodiment is based on Embodiments 1 and 2, such as Figure 4 As shown, a method for testing distributed reconnaissance and jamming equipment, applied to any of the above systems, includes the following steps: S1. Configure the device under test and the interference device corresponding to the target under test in the test environment according to the configuration scheme of the target under test and the interference device corresponding to the target under test.

[0049] Optionally, based on the configuration scheme of the target under test and the corresponding interference device, the device under test and the interference device in the test environment are configured, including: Based on the number of the target under test and the number of the corresponding jamming devices, configure the same number of devices under test and the same number of jamming devices in the test environment as the number of the target under test. Based on the orientation of the jamming device relative to the target under test, configure the orientation of the jamming device relative to the target under test in the test environment.

[0050] Optionally, the test platform retrieves the configuration scheme of the jamming device corresponding to the target under test (DUT) from the database based on the unique identifier of the DUT. Then, based on the number of DUTs and their corresponding jamming devices, it configures the same number of DUTs and jamming devices as the DUTs in the test environment. The test environment is configured as a shielded environment, i.e., the first shielded environment. Multiple second shielded environments, i.e., individual shielded test boxes, are preset in the test environment. Each shielded test box is equipped with a signal generator to simulate either the DUT or the jamming device. When the signal generator simulates the DUT, it acts as the DUT; when it simulates the jamming device, it acts as the jamming device. Generally, the number of shielded test boxes in the test environment is greater than the number of jamming devices. When configuring the DUTs and jamming devices in the test environment, we simply activate the corresponding number of shielded test boxes based on the number of jamming devices.

[0051] Optionally, the shielded test box in the test environment includes a first shielded test box as the center and multiple second shielded test boxes distributed on the circumference. Generally, the signal generating device in the first shielded test box is configured to simulate the target under test, and the signal generating device in the second shielded test box is configured to simulate the interference device.

[0052] Furthermore, based on the configuration scheme of the target under test and the corresponding interference device, the device under test and the interference device in the test environment are configured, including: Configure the signal generator in the first shielded test box to simulate the target under test; Based on the orientation of the interference device corresponding to the target under test relative to the target under test, a second shielding test box corresponding to the number of interference devices is selected in the second shielding test box, and the signal generating device in it is configured to simulate the target under test. The basis for selecting the second shielding test box corresponding to the number of interference devices is that the deviation between the orientation of the second shielding test box relative to the first shielding test box and the orientation of the interference device corresponding to the target under test relative to the target under test is the smallest.

[0053] Furthermore, when the shielding test box is set on the mobile platform, the orientation of the second shielding test box relative to the first shielding test box is matched with the orientation of the interference device corresponding to the target under test relative to the target under test by controlling the mobile platform to move in a circle.

[0054] S2. The test platform obtains the test plan based on the working parameters of the target under test and the corresponding interference device.

[0055] Specifically, the operating parameters of the target under test and the corresponding interference device include: operating frequency band, interference frequency band, power range, bandwidth, modulation method, triggering logic, coverage range, etc.

[0056] The operating parameters of jamming devices also include operating modes, such as suppression, deception, noise, modulation, and repeater modes.

[0057] Specifically, a test plan can be a program used to control the operation of the target under test and the jamming device. This program is generally used to control the operation of the target under test and its corresponding jamming device, such as: The operating frequency band of the target under test: 2.2GHz-2.5GHz; The operating power of the target under test: 600W-1000W; The jamming device supports wideband suppression at the 2.3GHz center frequency. Interference power: 2000W; The workflow involves repeatedly executing the following steps: 0s-10s: Interference-free baseline acquisition; 10s-40s: Enable broadband suppression interference; 40s-50s: Stop the interference and observe the recovery process; 50s-80s: Intermittent interference, turning on every 2 seconds and off every 1 second; 80s-90s: Switch to narrowband tracking jamming, the center frequency drifts with the main reconnaissance frequency of the device under test.

[0058] S3. The test platform controls the device under test and the interference device according to the test plan, so that the device under test and the interference device simulate the target under test and the corresponding interference device in the test environment.

[0059] Optionally, the test platform controls the device under test and interfering devices according to the test plan, including: The test platform configures amplifiers and / or attenuators for the antenna based on the target under test and the number of interference devices corresponding to the target under test; The test platform obtains the operating parameters of the target under test and the corresponding interference device based on the target under test and the configuration scheme of the target under test; According to the test plan, the test platform controls the test device, the interference device, and the amplifier based on the operating parameters of the target under test and the corresponding interference device. According to the test plan, the test platform controls the attenuator based on the distance between the target under test and the corresponding interference device.

[0060] Optionally, the test platform, according to the test plan, controls the device under test, the interference device, and the amplifier based on the operating parameters of the target under test and the corresponding interference device, including: The testing platform obtains the operating parameter range of the target under test and the operating parameter range of the device under test according to the test plan; Based on the operating parameter range of the target under test and the operating parameter range of the device under test, obtain the gain configuration scheme of the amplifier corresponding to the device under test; Based on the gain configuration scheme of the amplifier corresponding to the device under test, and based on the test plan, the device under test and the amplifier corresponding to the device under test are controlled. The test platform obtains the operating parameter range of the jamming device and the operating parameter range of the jamming equipment according to the test plan; Based on the operating parameter ranges of the jamming device and the jamming equipment, obtain the gain configuration scheme of the amplifier corresponding to the jamming equipment; Based on the gain configuration scheme of the amplifier corresponding to the interference device, and based on the test plan, the interference device and its corresponding amplifier are controlled.

[0061] Specifically, if the operating power of the target under test is 600W-1000W, the maximum operating power of the device under test is 250W, the gain of the amplifier corresponding to the device under test is 5 times, and based on the test plan, the device under test is controlled to operate at one-fifth of the operating power of the target under test in the test plan.

[0062] Optionally, the test platform controls the attenuator based on the distance between the target under test and the corresponding interference device, according to the test plan, including: According to FSPL(dB) = 32.45 + 20log 10 ( f )+20log 10 ( d Calculate the signal attenuation caused by the distance between the target and the corresponding interference device, where FSPL (dB) is the free space path loss expressed in decibels. f The operating frequency of the jamming device is expressed in MHz. d The distance between the jamming device and the target being measured; Based on the FSPL (dB) corresponding to each jamming device, the attenuator connected to the jamming equipment corresponding to that jamming device is controlled.

[0063] S4. The test platform obtains reconnaissance data of the test environment through reconnaissance equipment, and obtains test results based on the reconnaissance data.

[0064] Optionally, the testing platform obtains reconnaissance data of the testing environment through reconnaissance equipment, and obtains test results based on the reconnaissance data, including: The testing platform obtains reconnaissance data of the testing environment through reconnaissance equipment, and then preprocesses the reconnaissance data to obtain the test data; Based on the test data, analyze the correlation between the test data and the device under test; Test results are obtained based on the correlation between the test data and the device under test.

[0065] Optionally, based on the test data, analyze the correlation between the test data and the device under test, including: After shutting down all jamming devices, a new set of reconnaissance data of the test environment is obtained through reconnaissance equipment. The working data of the device under test is then obtained after preprocessing the reconnaissance data. The correlation between the test data and the working data of the device under test is obtained based on the correlation between the test data and the device under test.

[0066] Specifically, the correlation between test data and the operating data of the device under test can be obtained by analyzing one or more of the following: cross-correlation function, normalized correlation, cross-power spectrum, coherence function, and Pearson coefficient. Generally, time alignment is performed using the cross-correlation function, frequency correlation is determined using the coherence function, and finally, the correlation of propagation characteristics is determined using phase analysis.

[0067] This embodiment provides a method for testing electronic equipment using a movable shielded test box, which further solves the problem that traditional test systems may not be able to fully reflect the performance of equipment in actual combat in some key tests, thus affecting the performance evaluation and improvement of equipment.

The computer device may include: a processor 101, such as a central processing unit (CPU), a communication bus 102, a user interface 104, a network interface 103, and a memory 105. The communication bus 102 is used to enable communication between these components. The user interface 104 may include a display screen and an input unit such as a keyboard. Optionally, the user interface 104 may also include a standard wired interface or a wireless interface. The network interface 103 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 105 may be a storage device independent of the aforementioned processor 101. The memory 105 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as at least one disk storage device. The processor 101 may be a general-purpose processor, including a central processing unit, a network processor, etc., or it may be a digital signal processor, an application-specific integrated circuit, a field-programmable gate array or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component.
