[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides a high-field strength test system, which includes a radiation source generating device and a test component. The radiation source generating device includes: a signal source for generating an electrical signal of a specific frequency; multiple power amplifiers for amplifying the electrical signal to a required level; multiple high-gain radiation antennas, the high-gain radiation antennas corresponding to the power amplifiers one by one, and the multiple high-gain radiation antennas are respectively used to convert the amplified electrical signals into electromagnetic waves, and control the energy of the electromagnetic waves to focus on the same target position so that the electric field strength at the target position reaches a preset value; the test component includes: a receiving antenna for capturing the superimposed electromagnetic waves radiated by the multiple high-gain radiation antennas at the target position, and converting the superimposed electromagnetic waves into an electrical signal to be measured; an analysis device for analyzing the electrical signal to be measured to measure the electric field strength at the target position.

[0032] The analysis device includes: an attenuator for attenuating the electrical signal to be measured to within the test range of the field strength meter; and a field strength meter for calculating the electric field strength at the target position according to a preset field strength calculation formula.

[0033] Based on the first aspect, in the embodiment of the present application, the field strength calculation formula is as follows:

[0034]

[0035] In formula (1), E represents the electric field intensity at the target position, P r represents the power of the superimposed electromagnetic wave received by the receiving antenna, η0 represents the free space wave impedance, G r Indicates the gain of the receiving antenna.

[0036] In this embodiment, the five main parts of the test system are mainly described, namely, multiple power amplifiers (power amplifier 1, power amplifier 2, ..., power amplifier n), multiple high-gain radiating antennas (high-gain radiating antenna (Ant1), high-gain radiating antenna, ..., high-gain radiating antenna (Antn)), receiving antenna, attenuator and field strength meter. Figure 1 As shown, power amplifiers 1, 2, ..., and n, and high-gain radiating antennas (Ant1), ..., and (Antn) are used to cost-effectively simulate the high electric field strength radiated by high-power devices in space. The receiving antenna, attenuator, and field strength meter are used to measure field strengths exceeding the meter's range.

[0037] In this embodiment, the five main parts of the test system are mainly described, namely the power amplifier, high-gain radiating antenna, receiving antenna, attenuator and field strength meter. Figure 1 As shown, the power amplifier and high-gain radiating antenna are used to generate a sufficiently large electric field strength in the radiation link; the receiving antenna, attenuator and field strength meter are used to measure the field strength value of the large field strength exceeding the range of the field strength meter.

[0038] It is known that the transmission power and gain of an antenna are closely related to the electric field strength in space:

[0039]

[0040] In formula (2), 1.42 is the correction coefficient, 30 is the constant coefficient, P t Represents the radiated power of the high-gain radiating antenna, G trepresents the radiation gain of a high-gain radiating antenna, and d represents the electromagnetic wave transmission distance. The transmission power of an antenna is closely related to the output power of a power amplifier. However, high-output-power power amplifiers are expensive. Therefore, the present invention uses a high-gain radiating antenna to enhance the electric field strength on the antenna radiation link. However, the electric field strength radiated by a single antenna often cannot reach the electric field strength radiated by a high-power device. Therefore, the test system proposed in this embodiment uses multiple high-gain radiating antennas and utilizes the superposition theorem of electric field strength to ensure that the electric field strength on the radiation link reaches the high electric field strength radiated by the high-power device. For example, if the electric field strength of a high-power device is 6000V / m at 1 meter from its radiation link, a radiating antenna with an output power of 225W and a gain of 22dBi can only generate an electric field strength of 1468V / m at the same point. If a single radiating antenna is used to achieve an electric field strength of 6000V / m, a radiating antenna with a gain of at least 43dBi is required, which is more difficult to design. At this time, multiple radiating antennas with a gain of 22dBi can be used, and based on the superposition principle of electric field strength, the total electric field strength at 1 meter on the radiation link can reach 6000V / m, thereby simulating the radiation characteristics of high-power equipment at a low cost.

[0041] Furthermore, the receiving antenna receives the signal generated by the radiating antenna array and uses an attenuator to attenuate the signal by a factor of n, reducing the corresponding field strength value to within the measuring range of the field strength meter. After reading the measured value on the field strength meter and amplifying it by a factor of n, the actual field strength value of the high-power device on the radiating link can be calculated.

[0042] In summary, the high-field strength test system proposed in this embodiment can simulate the electric field strength radiated by high-power equipment at a low cost, and measure the high-field strength value on the radiation link using a small-range field strength meter.

[0043] Example 2

[0044] This example simulates the solution in Example 1 to verify its effectiveness. In this example, multiple high-gain radiating antennas are used to superimpose the radiation field strength to simulate the radiation characteristics of high-power devices. Therefore, this section primarily demonstrates the effectiveness of multiple high-gain antennas in superimposing the radiation field strength.

[0045] In the simulation design, three groups of identical horn antennas are selected (to reduce the degree of uneven field strength at the target location (area)). Their operating frequency is 12 GHz and their gain is 19.3 dBi. They are marked as antenna 1, antenna 2, and antenna 3. Figure 2We tested and analyzed the system in the CST simulation environment using the arrangement shown in the figure. The red dashed lines represent the central radiation links of each antenna, verifying the feasibility and effectiveness of achieving high radiation field strength through multi-antenna superposition.

[0046] from Figure 2 The placement diagram shows that the three antennas are arranged around a circle with a radius of 1500mm. Specifically, the high-gain radiating antennas maintain consistent heights and elevation angles, and their distances from the target location. The high-gain radiating antennas are evenly distributed in an arc centered at the target location, with adjacent antennas' azimuth angles differing by 30°. This arrangement not only creates a stronger composite field strength but also maximizes the simulation of the radiation distribution characteristics of high-power devices in real-world environments, providing theoretical basis and experimental support for related applications.

[0047] Figure 3 A schematic diagram of the superposition distribution of the field strength radiated by three high-gain antennas is shown. The figure clearly shows the individual radiation field strength distribution of each antenna, as well as the comprehensive field strength distribution characteristics after their spatial superposition. In particular, in the area marked by the dotted box in the figure, the field strength value is significantly enhanced, indicating that multiple high-gain antennas have formed a good field strength superposition effect in this area, thereby effectively improving the overall radiation field strength level. This result verifies that by rationally arranging multiple high-gain antennas, accurate simulation of high-power radiation environments can be achieved. This experimental result provides an important theoretical basis and practical reference for the subsequent optimization of antenna arrangement and improvement of the radiation field strength control accuracy.

[0048] On this basis, this embodiment further analyzes the field strength superposition on the central radiation link of antenna 2, and the simulation results are as follows: Figure 4 As shown in the figure, since Antenna 1 and Antenna 3 are symmetrically arranged relative to the central radiating link, their radiated field strength characteristics on this link are consistent, resulting in complete overlap of their field strength curves. Furthermore, since Antenna 2 is located directly on the central radiating link, its radiated field strength is slightly higher than that of Antenna 1 and Antenna 3, further demonstrating the influence of antenna arrangement on field strength distribution.

[0049] From the simulation results, the field intensity superposition curve shows a certain degree of fluctuation, which is mainly attributed to the fact that the aperture surfaces of the three antennas are not in the same plane. Figure 3 This is also reflected in the red dashed box enlargement, indicating that the field intensity superposition value fluctuates in space. However, the peak value of the simulated field intensity superposition curve is consistent with the theoretical calculation of the field intensity superposition result, indicating that the simulation results meet expectations.

[0050] Further analysis of the simulation data shows that the field intensity superposition reaches its maximum value of approximately 3300 V / m at a distance of 1500 mm from the center-radial link. This result demonstrates that when three high-gain antennas are arranged symmetrically along a circle with a radius of 1500 mm, their radiation field intensity can achieve ideal linear superposition on the center-radial link, effectively improving the radiation field intensity level in this area and providing a feasible solution for high-power radiation simulation.

[0051] Example 3

[0052] This embodiment is intended to further verify the applicability of the present invention. In this embodiment, the number of antennas is increased to five, which are marked as antenna 1, antenna 2, antenna 3, antenna 4 and antenna 5 respectively. Figure 5 The arrangement shown was tested in the CST simulation environment, where the dashed lines represent the center-radial links of each antenna. The test results show that the five antennas are evenly distributed on a circle with a radius of 1500mm, with the center-radial links between adjacent antennas at an angle of 15°. Figure 6 A schematic diagram shows the superimposed distribution of field strength radiated by five antennas. The figure clearly shows the individual radiation characteristics of each antenna and the combined field strength distribution after their spatial superposition. In particular, the radiated field strength is significantly enhanced in the area indicated by the red dashed line, demonstrating that the five antennas achieve good field strength superposition in this area.

[0053] Similarly, the field strength superposition on the central radiation link where antenna 3 is located is further analyzed, and the simulation results are as follows: Figure 7 As shown in the figure, it can be observed that since Antenna 1 and Antenna 5, as well as Antenna 2 and Antenna 4, are symmetrical about the central radiating link, their radiated field strength distributions on this link are identical, resulting in complete overlap of the corresponding field strength curves. Furthermore, since Antenna 3 is located on the central radiating link, its radiated field strength is slightly higher than that of the other four antennas, which is consistent with previous observations in the three-antenna system.

[0054] However, compared with the three-antenna system, the five antenna apertures are not in the same plane, the number of antennas increases, and the azimuth angle difference between two adjacent radiating antennas is smaller, resulting in a more complex superimposed field strength distribution. Figure 6 The red dashed line enlarges the box. Therefore, the fluctuation characteristics of the simulated field strength superposition curve differ somewhat from those of a three-antenna system. In particular, at the 1500mm position, the superimposed field strength decreases, failing to fully reach the maximum theoretical superposition field strength of the five antennas. However, the theoretical maximum superposition value is achieved at approximately 1700mm. Prioritizing the effect of mutual influence between adjacent radiating antennas, in this embodiment, the azimuth angles of two adjacent high-gain radiating antennas must differ by at least 15°.

[0055] Further analysis of the simulation data reveals that the superposition of the field strength reaches its maximum value of 4858 V / m at the 1713 mm position. This result demonstrates that, when the five antennas are arranged symmetrically along a circle with a radius of 1500 mm, the superposition of the field strength decreases around 1500 mm from the center of the radiation link, ultimately achieving the strongest radiation field at 1713 mm. This characteristic further validates the effectiveness of multi-antenna cooperative radiation and demonstrates that the scheme can simulate the high field strengths radiated by high-power devices, providing a reliable simulation basis for high-field intensity experimental research.

[0056] Example 4

[0059] With the goal of minimum energy consumption, the number n of high-gain radiating antennas and the radiation gain of the high-gain radiating antennas are determined, and the n high-gain radiating antennas are arranged according to preset rules. The n high-gain radiating antennas respectively emit and control the energy of electromagnetic waves to focus on the target position, so that the electric field strength at the target position reaches the expected value.

[0060] Furthermore, the determination of the number n of high-gain radiating antennas includes: if the electric field intensity caused by n high-gain radiating antennas at the target position can be stabilized at a maximum of E n , and the expected value of the electric field strength at the target position E q Satisfaction: E n-1 ≤E q <E n , then the number of high-gain radiating antennas is determined to be n.

[0061] By arranging a reasonable number of high-gain radiating antennas, the construction cost of the system can be controlled while meeting the electric field strength requirements. This is economical, efficient, flexible and controllable.

[0062] Furthermore, the radiation powers of the n high-gain radiating antennas are equal, which ensures the symmetry of the array of n high-gain radiating antennas and improves the uniformity and stability of the field intensity distribution at the target location (area).
