[0027] The technical scheme in the embodiment of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0029] In order to evaluate the feasibility of the radar protection cover, the radar is generally installed on the car and tested together with the car body. However, this may result in the car body having a greater impact on the radar and making the car body unable to adapt to the radar. In order to ensure the performance of the radar, the radar or the car body needs to be replaced, which wastes time and economic costs.

[0030] Therefore, the present application provides a method for manufacturing a radar protection cover, which can take the performance and adaptation relationship of the radar into consideration at the beginning of the design of the radar protection cover. After the radar protection cover, that is, the car shell, is manufactured, when the car shell and the radar are tested, it can also be ensured that the car shell and the radar cooperate to fully exert the performance of the radar, and the radar performance can be guaranteed without replacing the radar or the car shell, thereby saving time and economic costs.

[0031] Figure 1 The method for manufacturing a radar protection cover provided by an embodiment of the present invention includes:

[0032] S101, obtaining material information of the radar protection cover to be manufactured;

[0033] S102, using the material information to perform electromagnetic simulation to produce a predetermined number of first radar protection covers with different thicknesses;

[0034] S103, installing a simulated radar on all first radar protection covers, the simulated radar having a preset central frequency, and installing the first radar protection covers at a preset angle and a preset distance of the vehicle protection, and the first radar protection covers have a predetermined tilt angle at this position;

[0035] S104, performing a simulated radar test on the first radar protection cover under different working conditions to obtain radar pattern data under each working condition;

[0036] S105, analyzing the pattern data to evaluate whether the simulated radar performance under the working conditions corresponding to the pattern data meets the predetermined conditions;

[0037] S106. If the predetermined conditions are met, the data of the first radar protection cover having the corresponding preset center frequency, preset thickness, preset angle and preset distance from the vehicle guard, and preset tilt angle are output to obtain the target radar protection cover according to the data.

[0038] Therefore, the method for manufacturing the radar protection cover provided in the present embodiment can take into account factors that may affect the performance of the radar, such as the center frequency of the radar, the thickness of the radar protection cover, the preset angle and distance at which the radar protection cover is installed on the vehicle body, and the predetermined inclination angle of the radar protection cover at this position, before manufacturing the radar protection cover. This can ensure a better fit between the radar and the manufactured radar protection cover, thereby giving full play to the performance of the radar. There is no need to replace the radar or the vehicle shell to ensure the radar performance during testing, thereby saving time and economic costs.

[0039] In some embodiments, the material information of the radar protection cover in step S101 includes the dielectric constant Dk and the dielectric loss factor Df. Since the radar protection cover forms a shield in front of the radar, the dielectric constant Dk and the dielectric loss factor Df of the radar protection cover itself have a greater impact on the radar performance. Therefore, in subsequent steps, it is necessary to consider the impact of the dielectric constant Dk and the dielectric loss factor Df of the radar protection cover on the radar wave.

[0040] In some embodiments, the first radar protection cover in step S102 is a simulated radar protection cover, that is, a constructed virtual radar protection cover model. The virtual radar protection cover model can be used according to the above-mentioned material information to enable the virtual radar protection cover model to filter, reflect, and other scenarios on virtual radar signals when in use, so as to simulate the scenario where a real radar signal passes through a real radar protection cover, and the thickness of the first radar protection cover is greater than or equal to a preset thickness, wherein the preset thickness is a processing accuracy value that the manufacturer can achieve when the manufacturer processes and produces the radar protection cover. By making the thickness of the first radar protection cover greater than or equal to the preset thickness, it is possible to ensure that the radar protection cover produced subsequently has a thickness range within a certain thickness range. Therefore, even if the thickness of the radar protection cover fluctuates during actual production, the performance of the radar can be guaranteed to be stable.

[0041] Therefore, in some embodiments, the step of using the material information to perform electromagnetic simulation to produce a predetermined number of first radar protection covers with different thicknesses may include:

[0042] using the material information of the radome to calculate the difference between the performance of the radar signal before passing through the radome and the performance of the radar signal after passing through radomes of different thicknesses;

[0043] First radar protection covers of different thicknesses are manufactured, and radar performance values ​​are assigned to the first radar protection covers of different thicknesses according to the difference.

[0044] Among them, the performance of the radar signal before passing through the protective cover is the radar's transmission performance, and the performance of the radar signal after passing through the protective cover is the actual performance. These two performance parameters are fixed values ​​under ideal conditions. By calculating the difference between the transmission performance and the actual performance, in subsequent testing, under non-ideal conditions, the radar's transmission performance and the difference are known, and the actual performance of the radar can be calculated.

[0045] In some embodiments, step S103 provides the installation specifications of the radar protection cover, wherein there are at least two preset center frequencies, and there are at least two preset angles, preset distances, and preset tilt angles. For example, in a radar with four thicknesses A1, A2, A3, and A4, the installation distances may be B1, B2, B3, and B4, the installation angles C1, C2, C3, and C4, the center frequencies of the radar operation are D1, D2, D3, and D4, and the installation method of the protection cover is an upper tilt angle E1 and / or a lower tilt angle E2. Under the conditions of A1, B1, C1, D1, and E1, a simulation test is performed using step S104 to collect radar pattern data under working conditions. In some embodiments, the radar pattern data includes radar signal-to-noise ratio and angle measurement performance, which can be found in Figure 2 and Figure 3 , Figure 2 represents the linear variation between the azimuth and radar signal-to-noise ratio data, Figure 3 It represents the linear change between azimuth and azimuth error, that is, the angle measurement performance.

[0046] In step S105, the predetermined condition is that the radar performance can meet the conditions for use, for example Figure 2 The radar signal-to-noise ratio in is greater than or equal to 50, or / and, Figure 3 The angle measurement performance result in is greater than or equal to 0.1.

[0047] In some embodiments, the first radar protection cover is a flat-plate radar protection cover. In this embodiment, the vehicle-mounted radar, especially the vehicle-mounted millimeter-wave radar, is relatively small in size. Therefore, in actual application, the protection cover that blocks the radar can be approximately regarded as a flat plate. In this application, the first radar protection cover is made into a flat plate, which can meet the actual application and reduce the simulation cost. In other embodiments, if there is a demand for a special-shaped radar protection cover, the special-shaped radar protection cover can also be simulated and manufactured, and this embodiment does not limit it.

[0048] In some embodiments, after the step of actually producing the first radar protection cover having a corresponding thickness, a preset angle and a preset distance from the vehicle guard, a preset tilt angle, and a simulated radar with a preset center frequency, the production method further includes: performing an actual radar test on the actually produced radar protection cover and obtaining a test result; and using the test result to verify the result of the simulated radar test.

[0049] In this embodiment, after the simulation test, the actual radar protection cover produced in accordance with the simulation test can also be tested, and the test results can be used to verify the results of the simulation test. In some embodiments, the simulation test results and the test results can be input into the convolutional neural network as input data for training to obtain a simulation correction model. The correction model is used to output the corrected simulation test results. In subsequent steps, if simulation testing is still required, the simulation test results can be input into the simulation correction model to output the corrected test results.

[0050] In some embodiments, in the step of performing a simulated radar test on the first radar protection cover under different working conditions, the test environment is a microwave darkroom. The microwave darkroom test can measure the scattering characteristics of the target to the incident radar wave, so as to obtain the radar cross section of the target. Through the microwave darkroom test, the scattering effect of the target under the radar wave can be measured.
