Description

Technical Field

[0001] The present invention belongs to the technical field of communication antenna structure adjustment, and particularly relates to a method, device and electronic equipment for constructing an adjustment matrix of a reflector antenna panel optimized based on orthogonal experiments. Background Art

[0002] When a large reflector antenna deforms under the action of external loads such as gravity, temperature and wind, it is necessary to construct an adjustment matrix of the reflector antenna panel to determine the adjustment amount of the actuator (a device that can generate actions or forces to achieve precise adjustment and control of the reflector antenna panel). Then, the deformation of the reflector antenna panel is compensated according to the determined adjustment amount. The key problem here is how to accurately construct the adjustment matrix of the reflector antenna panel. The reflector antenna panel is a reflecting surface assembled by many small reflector antenna panels in a specified shape. For the active main reflector antenna panel, the existing method for constructing the adjustment matrix of the reflector antenna panel is as follows: for the to-be-processed antenna panel i (the to-be-processed antenna panel is a small reflector antenna panel that forms an entire reflector antenna panel), first, unit normal displacement constraints are respectively applied to the nodes where the 4 actuators of the antenna panel i are located, and the deformation functions corresponding to the 4 actuators of the antenna panel i are obtained based on the finite element method. Then, unit normal constraints are simultaneously applied to the 4 actuators of the antenna panel i to obtain the deformation function. Different weights are assigned to these five deformation functions to construct the adjustment matrix of the antenna panel i. The adjustment matrices of each to-be-processed antenna panel are obtained in turn in the above manner, and are aggregated into the adjustment matrix of the entire antenna panel. However, the inventor found in the process of implementing the present invention that: in the existing method for constructing the adjustment matrix of the reflector antenna panel, since multiple deformation functions need to be obtained for each to-be-processed antenna panel to construct the adjustment matrix of the to-be-processed antenna panel, this results in a large number of working conditions (working conditions refer to various conditions and states when the antenna is actually working) required by the existing technology and low modeling efficiency; then, the adjustment matrices corresponding to all to-be-processed antenna panels are aggregated into the adjustment matrix of the entire antenna panel, which makes the matrix construction accuracy limited by the combined working condition distribution, resulting in the fact that the existing technology cannot fully consider both the simulation cost and the modeling accuracy. Summary of the Invention

[0064] Next, the technical solutions in the embodiments of the present invention will be described with reference to the accompanying drawings in the embodiments of the present invention. It should be understood that the preferred embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0065] The method provided by the embodiment of the present invention can be applied to the generation of the adjustment matrix of the active main reflector antenna in engineering. Figure 1 A flowchart of a method for constructing a reflector antenna panel adjustment matrix optimized based on orthogonal experiment provided for the embodiment of the present invention, as Figure 1 shown, the method includes:

[0066] S101: Obtain a set of antenna panels to be processed corresponding to the reflector antenna;

[0067] The active main reflector antenna is assembled by splicing multiple antenna panels, and these antenna panels jointly undertake the tasks of receiving and converging radio waves. Usually, each antenna panel has 4 adjustment mechanisms, namely 4 actuators, which are respectively located at the 4 vertices of the antenna panel, and the adjustment of the antenna panel is achieved by adjusting the actuators located at the 4 vertices.

[0068] In practical applications, a finite element model of a reflector antenna and a finite element model of each antenna panel in the reflector antenna can be constructed according to the structural parameters and material property parameters of the reflector antenna. Among them, the structural parameters of an active main reflector antenna can include antenna panels, back ribs, back frames, central bodies, sub-reflectors, pedestals, etc.; the material property parameters can include density, Poisson's ratio, elastic modulus, thermal expansion coefficient, etc.

[0069] S102: For each to-be-processed antenna panel in the set of to-be-processed antenna panels, use a preset finite element model to obtain the finite element model of the to-be-processed antenna panel;

[0070] In a specific embodiment, it can be based on finite element analysis software. In the finite element model of the reflector antenna, the nodes corresponding to a single antenna panel are selected through interface operations, and then the finite element model of the single antenna panel is obtained.

[0071] S103: Obtain the number of actuators and the types of displacement states of the actuators of the to-be-processed antenna panel, and based on the model of the to-be-processed antenna panel, obtain the adjustment combination working condition set of the to-be-processed antenna panel according to the number of actuators and the types of displacement states of the actuators of the to-be-processed antenna panel;

[0072] In a specific embodiment, the types of displacement states of the actuators can include: displacement upward along the normal direction, displacement downward along the normal direction, and displacement being 0; based on the model of the to-be-processed antenna panel, according to the number of actuators and the types of displacement states of the actuators of the to-be-processed antenna panel, the steps of obtaining the adjustment combination working condition set of the to-be-processed antenna panel can include:

[0073] Based on the model of the to-be-processed antenna panel, according to the types of displacement states of the actuators and the types of displacement states of each actuator of the to-be-processed antenna panel, determine the initial adjustment combination working condition set;

[0074] Remove the adjustment combination working conditions in the initial adjustment combination working condition set where the displacement states of all actuators are displacement being 0, and obtain the adjustment combination working condition set of the to-be-processed antenna panel.

[0075] For example, in a specific embodiment, since the reflector antenna generally deforms by a few millimeters under the action of external forces such as gravity, temperature, or wind, it can be set that the 4 actuators of the to-be-processed antenna panel all have three displacement states, namely: displacement upward along the normal direction by 1 mm, displacement downward along the normal direction by 1 mm, and actuator displacement being 0, where the upward displacement is positive and the downward displacement is negative; so for the actuators of the to-be-processed antenna panel, excluding the case where the displacement of all actuators is 0, there are a total of 3 4 -1 = 80 kinds of adjustment combination working conditions.

[0076] S104: From the adjustment combination working conditions, determine the template adjustment combination set, and perform finite element simulation on the template adjustment combination set to obtain the deformation data corresponding to the antenna panel to be processed;

[0077] Specifically, the orthogonal test method can be used to determine the template adjustment combination set from the adjustment combination working conditions, and perform finite element simulation on the template adjustment combination set to obtain the deformation data corresponding to the antenna panel to be processed.

[0078] If, as in the prior art, finite element simulation is performed for each adjustment combination working condition, it will cause problems of high cost and long calculation time. Therefore, the present invention innovatively uses the orthogonal test method to determine the template adjustment combination set from the adjustment combination working conditions, and then performs finite element simulation on the template adjustment combination set. Compared with the prior art, the number of simulations is significantly reduced while ensuring the accuracy of constructing the adjustment matrix.

[0079] The steps of using the orthogonal test method to determine the template adjustment combination set from the adjustment combination working conditions, and performing finite element simulation on the template adjustment combination set to obtain the deformation data corresponding to the antenna panel to be processed may include:

[0080] Based on a preset orthogonal table, obtain N adjustment combination working conditions from the adjustment combination working conditions as the template adjustment combination set, where N is a preset quantity;

[0081] Obtain the node coordinates of the actuators of the antenna panel to be processed, substitute the node coordinates into the normal vector calculation formula, calculate the unit normal vector of the node coordinates of the actuators of the antenna panel to be processed, and successively apply unit normal displacement constraints at the node positions of the actuators of the antenna panel to be processed, and obtain the deformation data corresponding to the antenna panel to be processed under N adjustment combination working conditions through finite element simulation [d1 a d2 a ...d N a , where a represents the antenna panel to be processed, and d i a represents the deformation data corresponding to the antenna panel to be processed under the i-th adjustment combination working condition, i is a natural number, and the value of i is 1, 2,..., N.

[0082] In the embodiment of the present invention, the L9 orthogonal table is selected. Only 9 template adjustment combination working conditions (also called typical working conditions) need to be selected from the 80 adjustment combination working conditions in S103 to replace all the adjustment combination working conditions for constructing the adjustment matrix of the reflector antenna panel.

[0083] The standard orthogonal table of L9 is shown in Table 1:

[0084] Table 1

[0085]

[0086] Among them, 1 in the L9 standard orthogonal array represents the displacement upward along the normal direction, -1 represents the displacement downward along the normal direction, and 0 represents the displacement of 0. As can be seen from Table 1, each of the three possible displacement states of each actuator in the L9 standard orthogonal array only appears three times, so it is called a standard orthogonal array. However, according to step S103, the case where the displacements of the four actuators are all 0 needs to be removed, so the above L9 standard orthogonal array cannot be directly used and needs to be adjusted; in the embodiment of the present invention, in line with the orthogonal design principle, the number of occurrences of the three displacement states of the four actuators is made similar, so the first case where the displacements of the four actuators are all 0 is modified to the displacement state of one actuator being 1 and the displacements of the other three actuators being 0, so as to balance the number of occurrences of each displacement state of the four actuators at the minimum cost. The modified L9 orthogonal array is shown in Table 2:

[0087] Table 2

[0088]

[0089] The modified L9 orthogonal array is the preset orthogonal array in the embodiment of the present invention. Based on the modified L9 orthogonal array, nine adjusted combination working conditions are obtained from the 80 adjusted combination working condition sets in S103: (0, 0, 1, 0), (0, 1, -1, 1), (0, -1, 1, -1), (1, 0, 0, -1), (1, 1, -1, 0), (1, -1, 1, 1), (-1, 0, 0, 1), (-1, 1, -1, -1), (-1, -1, 1, 0) as the template adjustment combination set.

[0090] According to the nine selected template adjustment combination working conditions, for the antenna panel to be processed, the node coordinates of the four vertex actuators of the antenna panel to be processed are extracted, and the above node coordinates are brought into the normal vector calculation formula to obtain the normal vector of the antenna panel to be processed. Among them, the expression of the normal vector calculation formula is:

[0091] n x =-N x / 2f

[0092] n y =-N y / 2f

[0093] n = 1

[0094]

[0095] Among them, N x and N y are the x and y coordinates of the node where a single actuator is located respectively, n x , ny , n z are the normal vectors of the antenna panel to be processed on the x, y, and z axes respectively. n_norm is the unit normal vector after normalizing the normal vector of the antenna panel to be processed. According to the coordinates of the 4 actuator nodes, the unit normal vectors corresponding to each actuator can be obtained after calculation according to the formula.

[0096] For the antenna panel a to be processed, where a = 1, 2, 3... n, and n is the total number of panels of the antenna panels to be processed corresponding to the reflector antenna; the normal displacements of the 4 actuators under 9 adjustment combination conditions are split into the displacement constraints in the rectangular coordinate system applied in the finite element model of the antenna panel through the unit normal vectors of the actuators, and then the node deformation data [d1 a d2 a … d9 a of the antenna panel a under 9 adjustment combination conditions are extracted through finite element simulation.

[0097] S105: Construct a corresponding single-panel adjustment matrix for the antenna panel to be processed according to the deformation data corresponding to the antenna panel to be processed and the corresponding relationship between the deformation data and the adjustment amount;

[0098] Specifically, the steps of constructing a corresponding single-panel adjustment matrix for the antenna panel to be processed according to the deformation data corresponding to the antenna panel to be processed and the corresponding relationship between the deformation data and the adjustment amount may include:

[0099] According to the deformation data [d1 a d2 a ... d N a corresponding to the antenna panel to be processed, and the corresponding relationship d a = M a · A a , construct a corresponding single-panel adjustment matrix M a = d a · (A a ) T [[ID=4")]]· (A a (A a ) T ) -1 , where d a represents the deformation data [d1 a d2 a … d N a corresponding to the antenna panel to be processed, M a represents the adjustment matrix of the antenna panel to be processed, and A a represents the unit normal displacement applied by the actuator of the antenna panel to be processed, and A aRepresents the optimal adjustment amount matrix of the actuators for the antenna panel to be processed, (A a ) T Represents the transpose of the optimal adjustment amount matrix of the actuators for the antenna panel to be processed.

[0100] In a specific embodiment, the mapping relationship between the antenna panel node deformation data and the normal displacements applied by the four actuators of the panel is: d a = M a ·A a , where d a represents the node deformation data of the a-th antenna panel, M a represents the adjustment matrix of the a-th antenna panel, and A a represents the normal displacements applied by the four actuators of the a-th antenna panel.

[0101] The node deformation data under 9 adjustment combination conditions have been obtained through simulation, which are [d1 a d2 a …d9 a . Among the 9 adjustment combination conditions, for each adjustment combination condition, the adjustment values of the four actuators of the antenna panel a can be formed into a matrix, and this matrix is the optimal adjustment amount A a of the actuators of the antenna panel a under the current adjustment combination condition, where

[0102]

[0103] Therefore, through the actuator displacement state and the antenna panel node deformation data, the adjustment matrix M a of the antenna panel a can be constructed: where d a = M a ·A a ; d a ·(A a ) T = M a ·A a (A a ) T ; M a = d a ·(A a ) T ·(A a (A a ) T ) -1 .

[0104] S106: When obtaining the single-panel adjustment matrix corresponding to each antenna panel to be processed, construct the reflector antenna panel adjustment matrix for the reflector antenna according to the single-panel adjustment matrix corresponding to each antenna panel to be processed.

[0105] For each antenna panel to be processed in the set of antenna panels to be processed corresponding to the reflector antenna, an adjustment matrix M corresponding to each antenna panel to be processed is sequentially constructed 1 , …, M a ,... M n , and based on the adjustment matrix corresponding to each antenna panel to be processed, a reflector antenna panel adjustment matrix M corresponding to the reflector antenna is constructed. Among them,

[0106]

[0107] Therefore, the mapping relationship between the node deformation data of the reflector antenna (i.e., the entire reflector) and the actuator adjustment amount is: d = M · A, where d is the deformation data calculated by the reflector antenna panel adjustment matrix M under the adjustment of the reflector actuator adjustment amount A, and the adjustment amount A is the optimal adjustment amount A 1 , …, A a ,... A n composed of

[0108] In practical applications, after the step of constructing the reflector antenna panel adjustment matrix for the reflector antenna panel according to the single-panel adjustment matrix corresponding to each antenna panel to be processed, it may further include:

[0109] Obtain the actual deformation data of the reflector antenna;

[0110] According to the actual deformation data and the reflector antenna panel adjustment matrix, calculate the optimal adjustment amount of each actuator of the reflector antenna, and compensate each actuator of the reflector antenna according to the optimal adjustment amount.

[0111] That is, based on the reflector antenna panel adjustment matrix and the actual deformation data of the reflector, calculate the optimal adjustment amount of each actuator of the reflector antenna to achieve precise compensation. Specifically, after solving the reflector antenna panel adjustment matrix M, if a set of deformation data of the reflector antenna is provided, the optimal adjustment amount of all actuators of the reflector antenna under the current deformation data can be derived through formula. The following briefly describes the derivation process of the mapping relationship between the reflector antenna node deformation data and the actuator adjustment amount: The actuator adjustment amount A when the surface accuracy of the reflector antenna is optimal can be calculated according to the reflector antenna panel adjustment matrix M and the deformation data d of the reflector antenna under the action of external loads best . The derivation process is as follows: d = M · A best ; M T ·d = M T ·M · A best ; (M T ·M) -1·M T ·d = A best ; A best =(M T ·M) -1 ·M T ·d.

[0112] According to the above formula, the actuator adjustment amount A when the surface accuracy of the reflector antenna is optimal can be obtained. best .

[0113] In summary, the method provided by the embodiment of the present invention can screen out only a few template adjustment combination conditions from all adjustment combination conditions based on the orthogonal test. Only by processing these selected template adjustment combination conditions can the adjustment matrix of the reflector antenna panel be obtained. Compared with the method for constructing the adjustment matrix of the reflector antenna panel based on all adjustment combination conditions, which needs to process all adjustment combination conditions to obtain the adjustment matrix of the reflector antenna panel, the present invention can quickly construct the adjustment matrix of the reflector antenna panel, and at the same time ensure the accuracy of the adjustment matrix and reduce the time cost.

[0114] In addition, compared with the prior art, the method provided by the embodiment of the present invention has a higher approximation accuracy of the single-panel antenna adjustment matrix for the deformation of a single-panel antenna. When the reflector antenna is deformed, the surface accuracy of the entire reflector after adjustment with the actuator adjustment amount calculated based on the method provided by the embodiment of the present invention is higher.

[0115] To verify the effect of the method provided by the embodiment of the present invention, a simulation experiment is carried out on the method provided by the embodiment of the present invention. The specific simulation process is as follows:

[0116] Select an antenna with a diameter of 35 meters as the simulation object. The schematic diagram of the finite element structure of the 35-meter antenna is as Figure 2 shown, where Figure 2 the small blue square blocks in are the antenna panels to be processed. This simulation experiment respectively conducts simulations on the method for constructing the adjustment matrix of the reflector antenna panel based on the orthogonal test optimization provided by the embodiment of the present invention, the existing method for constructing the adjustment matrix of the reflector antenna panel based on all adjustment combination conditions, and the method for constructing the adjustment matrix of the reflector antenna panel based on the deformation function mentioned in the background technology. And the root mean square error and construction time of the surface of the reflector antenna after panel adjustment by the above methods are compared. The specific simulation results are shown in the following table:

[0117] Table III

[0118]

[0119] Table IV

[0120] Method Time Accuracy Based on the deformation function 1.7 min Lower Based on the fully adjusted combined work 20 min Very high Based on the orthogonal experiment 2 min Higher

[0121] Analysis of the data in Table 3 and Table 4 above shows that the accuracy of the reflector antenna panel adjustment matrix constructed based on the full-adjustment combined working conditions is the highest. After the panel adjustment, the reflector antenna in the looking-up and pointing-flat states has increased by approximately 25% compared to the looking-up and pointing-flat states after adjustment by the method based on the deformation function. For the reflector antenna panel adjustment matrix constructed using the orthogonal test method of the present invention, after adjustment, the accuracy of the reflector antenna in the looking-up and pointing-flat states has decreased by approximately 3% compared to the reflector antenna panel adjustment matrix constructed based on the full-adjustment combined working conditions, which is completely within the acceptable range. However, the time required to construct the reflector antenna panel adjustment matrix is shortened by 10 times compared to the method based on the full-adjustment combined working conditions. The method based on orthogonal test provided by the embodiments of the present invention takes approximately the same time to construct the reflector antenna panel adjustment matrix as the method based on the deformation function in the background art. However, the reflector antenna panel adjustment matrix constructed by the method provided by the embodiments of the present invention has higher accuracy, which can prove the effectiveness of the method provided by the embodiments of the present invention. Using the method provided by the embodiments of the present invention, a high-precision reflector antenna panel adjustment matrix can be constructed quickly.

[0122] Next, the approximation accuracy of the reflector antenna panel adjustment matrix constructed by the method provided by the embodiments of the present invention and the electrical performance of the reflector antenna after adjustment are compared with those of the reflector antenna panel adjustment matrix constructed by the disclosed method through simulation. The simulation process is as follows;

[0123] First, the approximation accuracy between the panel deformation data and the simulation data is calculated through the reflector antenna panel adjustment matrix. The process is as follows:

[0124] Refer to Figure 3 As shown in the schematic diagram of the reflector antenna panel divided into rings, a panel of the 5th ring in an antenna with a diameter of 35 meters is selected. Five groups of different adjustment values are randomly configured for the 4 actuators of this panel. Through the mapping relationship between the reflector antenna node deformation data and the actuator adjustment amount: d = M·A, the reflector antenna panel adjustment matrix constructed by the method provided by the embodiments of the present invention can be calculated. Under five groups of actuator adjustment amounts, the root mean square error newM_RMS of the antenna panel node deformation data calculated respectively is calculated; then the root mean square error M_RMS of the panel deformation data calculated by using the adjustment matrix constructed by the disclosed method is calculated; finally, it is compared with the root mean square error APDL_RMS of the panel deformation data directly obtained by finite element simulation, so as to verify the approximation accuracy of the reflector antenna panel adjustment matrices constructed by the two methods.

[0125] The simulation example is shown in Table 5:

[0126] Table 5

[0127]

[0128]

[0129] Analysis of the data in Table 5 shows that the root mean square error (RMSE) of the antenna panel calculated by the adjustment matrix constructed by the method provided in the embodiments of the present invention has an obvious reduction in the error newM_error compared with the RMSE of the antenna panel directly obtained by simulation. Compared with the M_error of the disclosed method, it can be proved that the adjustment matrix constructed by the method provided in the embodiments of the present invention has a higher approximation accuracy.

[0130] Secondly, verify that under the action of gravity, the far-field patterns before and after the adjustment of the antenna deformation data are compared to prove that the electrical performance after the adjustment of the adjustment matrix constructed by the method provided in the embodiments of the present invention is more ideal than that of the adjustment matrix constructed by the disclosed method.

[0131] Assume that the operating frequency of the reflector antenna is 96 GHz. The formula for calculating the antenna electrical performance through the aperture field is as follows:

[0132]

[0133] Among them, W(ρ′) represents the amplitude distribution on the antenna aperture surface, corresponding to the observation angle in the far field; σ is the projection area of the reflector on the xoy plane. 1 ≤ P ≤ 2, B is related to the edge taper and ET = 20lgB. Among them, Δp = 2(Δxcosα + Δycosβ + Δzcosγ)cosγ, and Δx, Δy, and Δz respectively represent the components of the total deformation in the x-axis, y-axis, and z-axis. cosα, cosβ, and cosγ respectively represent the unit cosines of the unit normal vector at the nodes on the reflector antenna in the x-axis, y-axis, and z-axis.

[0134] After obtaining the far-field patterns before and after the adjustment, extract the electrical performance indicators of the reflector antenna. The far-field patterns before and after the adjustment of the antenna panel under the antenna looking-up condition obtained according to the above antenna electrical performance formula can be specifically seen in Figure 4a and Figure 4b , and the far-field patterns before and after the adjustment of the panel under the antenna pointing-flat condition can be specifically seen in Figure 5a and Figure 5b . Table 6 is the electrical performance data obtained by analyzing the antenna looking-up and pointing-flat states.

[0135] Table 6

[0136]

[0137]

[0138] When the reflector antenna is in the elevation position, after the adjustment of the reflector antenna panel adjustment matrix constructed by the disclosed method, the gain losses in both the azimuth plane and the elevation plane are reduced to 0.208 dB. However, after the adjustment of the reflector antenna panel adjustment matrix constructed by the method provided in the embodiments of the present invention, the gain loss is reduced to 0.118 dB, and the reduction effect of the left and right first side lobe levels is better. It can be seen that the electrical performance of the antenna after the adjustment of the reflector antenna panel adjustment matrix constructed by the method provided in the embodiments of the present invention is better than before; when the reflector points horizontally, it can be concluded that the main lobe gain loss can be reduced after the adjustment of the reflector antenna panel matrix constructed by the method provided in the embodiments of the present invention, and from the data, the left and right first side lobe levels can also be slightly reduced. The simulation results show that the reflector antenna panel adjustment matrix constructed by the method provided in the embodiments of the present invention has better approximation accuracy and adjustment accuracy than the reflector antenna panel adjustment matrix constructed by the disclosed method, which proves the effectiveness of the method provided in the embodiments of the present invention.
