Description

Technical Field

[0001] This application relates to the field of array antenna control technology, and in particular, to a phased array antenna beam control method, device, equipment and medium. Background Art

[0002] Currently, the mainstream solutions for calculating wave control codes at home and abroad are mainly divided into three categories: The first category is the lookup table-based method. The computer calculates the wave control codes of each beam pointing angle, each frequency point, and each antenna element in advance and stores them in a storage chip such as FLASH (Flash Memory). When performing beam control work, the FPGA (Field Programmable Gate Array) reads the wave control code value of the storage chip to complete the phase shift function, and then realizes beamforming. However, when the array scale is large, the number of frequency points is large, and the number of wave positions is large, there will be a risk of large storage pressure and easy error of stored data. The second category is to calculate the wave control code by software such as a single-chip microcomputer or a DSP (Digital Signal Processor). However, the software calculation method has the disadvantage of slow phase distribution speed. The third category is to directly perform operations using an FPGA chip. However, since the FPGA chip does not have a floating-point operation function and occupies a large amount of resources when performing operations such as trigonometric functions, it cannot perform real-time calculations.

[0030] Figure 1 It is a schematic diagram of an exemplary system architecture shown in an exemplary embodiment of the present application.

[0031] Refer to Figure 1As shown, the system architecture may include a storage device 101 and a control device 102. Among them, the control device 102 may be at least one of a desktop Graphics Processing Unit (GPU) computer, a DSP, a Microcontroller Unit (MCU), an FPGA, etc. Relevant technicians can use the control device 102 to calculate the beam phase shift value according to the beam pointing angle, beam frequency, and array antenna quantization coordinate value by obtaining the beam control instruction information, array antenna quantization coordinate value, and amplitude-phase error value between array antenna channels, add the beam phase shift value and the amplitude-phase error data to obtain the beam correction phase shift value, and convert the beam correction phase shift value into a balanced vector signal to perform antenna beam control through the balanced vector signal. The storage device 101 is used to store the beam control instruction information, array antenna quantization coordinate value, and amplitude-phase error value between array antenna channels. In this embodiment, the storage device 101 uses Flash Memory or Random Access Memory (RAM), etc. to store the beam control instruction information, array antenna quantization coordinate value, and amplitude-phase error value between array antenna channels, and provides them to the control device 102 for processing.

[0032] Schematically, after the control device 102 obtains the beam control instruction information, array antenna quantization coordinate value, and amplitude-phase error value between array antenna channels from the storage device 101, it calculates the beam phase shift value according to the beam pointing angle, beam frequency, and array antenna quantization coordinate value, adds the beam phase shift value and the amplitude-phase error data to obtain the beam correction phase shift value, and converts the beam correction phase shift value into a balanced vector signal to perform antenna beam control through the balanced vector signal. Through the above process, by using the balanced vector signal for antenna beam control, it has the advantages of more accurate amplitude and phase modulation under the same voltage control and a wider bandwidth.

[0033] It should be noted that the phased array antenna beam control method provided by the embodiments of the present application is generally executed by the control device 102. Correspondingly, the phased array antenna beam control device is generally arranged in the control device 102.

[0034] The implementation details of the technical solutions of the embodiments of the present application are elaborated in detail below:

[0035] Figure 2 is a flowchart of the phased array antenna beam control method shown in an exemplary embodiment of the present application. The phased array antenna beam control method can be executed by a computing processing device, and the computing processing device can be Figure 1 the control device 102 shown in Figure 2As shown, the phased array antenna beam control method at least includes steps S210 to S230, which are introduced in detail as follows:

[0036] In step S210, beam control instruction information, array antenna quantization coordinate values, and amplitude-phase error values between array antenna channels are obtained. In an embodiment of the present application, the beam control instruction information includes a beam pointing angle and a beam frequency. The beam pointing angle is an angle in the phased array local coordinate system, and the beam pointing angle is obtained by rotating the angle in the geodetic coordinate system through the Euler coordinate rotation formula; the array antenna quantization coordinate values include the array antenna quantization coordinate values of the first preset coordinate axis and the array antenna quantization coordinate values of the second preset coordinate axis. The first preset coordinate axis is the x-axis in the phased array local coordinate system, and the second preset coordinate axis is the y-axis in the phased array local coordinate system, etc. The amplitude-phase error values between array antenna channels are determined during the calibration of the array antenna, and each array antenna has an amplitude-phase error value. The array antenna quantization coordinate values and the amplitude-phase error values between array antenna channels are pre-stored in a flash memory or other memory, which is convenient for directly obtaining them by reading when calculating the beam correction phase shift value.

[0037] In step S220, according to the beam pointing angle, beam frequency, and array antenna quantization coordinate values, a beam phase shift value is calculated; the beam phase shift value and the amplitude-phase error data are added to obtain a beam correction phase shift value. In an embodiment of the present application, the beam pointing angle includes a beam elevation angle and a beam azimuth angle. The process of calculating the beam phase shift value according to the beam pointing angle, beam frequency, and array antenna quantization coordinate values includes: obtaining the trigonometric function values of the beam elevation angle, the trigonometric function values of the beam azimuth angle, and the frequency conversion value of the beam frequency; determining the beam coordinate vector based on the trigonometric function values of the beam azimuth angle and the array antenna quantization coordinate values; multiplying the trigonometric function values of the beam elevation angle by the frequency conversion value to obtain a beam frequency adjustment value; multiplying the beam coordinate vector by the beam frequency adjustment value to obtain a beam phase shift value. In the flash memory or other memory, the trigonometric function values of each elevation angle, the trigonometric function values of each azimuth angle, and the frequency conversion values of each frequency are pre-stored. After obtaining the beam elevation angle, beam azimuth angle, and beam frequency, the beam elevation angle, beam azimuth angle, and beam frequency are respectively used as the look-up table addresses, and the trigonometric function values of the beam elevation angle are queried from the trigonometric function values of each elevation angle, the frequency conversion value of the beam frequency is queried from the frequency conversion values of each frequency, and the trigonometric function values of the beam azimuth angle are queried from the trigonometric function values of each azimuth angle through look-up tables, which makes up for the shortcoming that the control device (such as an FPGA) cannot perform floating-point operations in real time, and is convenient for the control device to quickly calculate the beam phase shift value according to the beam pointing angle, beam frequency, and array antenna quantization coordinate values.

[0038] In step S230, the beam correction phase shift value is converted into a balanced vector signal to perform antenna beam control through the balanced vector signal. In an embodiment of the present application, by obtaining beam control instruction information, array antenna quantization coordinate values, and amplitude-phase error values between array antenna channels, according to the beam pointing angle, beam frequency, and array antenna quantization coordinate values, the beam phase shift value is calculated. The beam phase shift value and amplitude-phase error data are added to obtain the beam correction phase shift value, and the beam correction phase shift value is converted into a balanced vector signal to perform antenna beam control through the balanced vector signal. In the above process, by using the balanced vector signal for antenna beam control, it has the advantages of more accurate amplitude and phase modulation under the same voltage control and a wider bandwidth.

[0039] In some embodiments of the present application, by means of look-up tables and a control device (e.g., FPGA) to calculate the beam correction phase shift value, it makes up for the lack of floating-point operation function of the control device, and improves the calculation rate of the control device (e.g., FPGA) for the beam correction phase shift value, and maintains the flexibility of the control device (e.g., FPGA) to calculate the beam correction phase shift value.

[0040] In an embodiment of the present application, the process of calculating the beam phase shift value according to the beam pointing angle, beam frequency, and array antenna quantization coordinate values includes:

[0041] Obtain the trigonometric function values of the beam pointing angle and the frequency conversion values of the beam frequency. In an embodiment of the present application, the beam pointing angle includes the beam elevation angle and the beam azimuth angle. In a flash memory or other memory, trigonometric function value tables of each elevation angle, trigonometric function value tables of each azimuth angle, and frequency conversion value tables of each frequency are pre-stored. After obtaining the beam elevation angle, beam azimuth angle, and beam frequency, the beam elevation angle, beam azimuth angle, and beam frequency are respectively used as the look-up table addresses, and the trigonometric function values of the beam elevation angle are obtained by looking up the trigonometric function value table of each elevation angle, the frequency conversion values of the beam frequency are obtained by looking up the frequency conversion value table of each frequency, and the trigonometric function values of the beam azimuth angle are obtained by looking up the trigonometric function value table of each azimuth angle.

[0042] Determine the beam coordinate vector based on the trigonometric function values of the beam azimuth angle and the quantized coordinate values of the array antenna. In an embodiment of the present application, if the trigonometric function values of the beam azimuth angle include the sine value of the beam azimuth angle and the cosine value of the beam azimuth angle, and the quantized coordinate values of the array antenna include the quantized coordinate values of the array antenna on the first preset coordinate axis and the quantized coordinate values of the array antenna on the second preset coordinate axis, then the process of multiplying the trigonometric function values of the beam azimuth angle by the quantized coordinate values of the array antenna to obtain the beam coordinate vector includes: multiplying the sine value of the beam azimuth angle by the quantized coordinate values of the array antenna on the second preset coordinate axis to obtain the first beam coordinate sub-vector; multiplying the cosine value of the beam azimuth angle by the quantized coordinate values of the array antenna on the first preset coordinate axis to obtain the second beam coordinate sub-vector; taking the sum of the first beam coordinate sub-vector and the second beam coordinate sub-vector as the beam coordinate vector.

[0043] In some embodiments of the present application, only the sine function values in the first quadrant (0° to 90°) are stored in the flash memory or other memories, and the trigonometric function values in other quadrant ranges can be obtained by converting the sine function values in the first quadrant range. This method can not only save storage space and storage resources, but also make up for the lack of floating-point operation function of the control device, and ensure the calculation speed and flexibility of the control device (such as FPGA) for calculating the beam correction phase shift value.

[0044] Multiply the trigonometric function values of the beam elevation angle by the frequency conversion value to obtain the beam frequency adjustment value. In an embodiment of the present application, the trigonometric function value of the beam elevation angle is the sine value of the beam elevation angle, and the calculation formula of the beam frequency adjustment value is as follows:

[0045] F = (-2πf / c)·sinθ Equation (1)

[0046] Where, F represents the beam frequency adjustment value, f represents the beam frequency, c represents the wave velocity, -2πf / c represents the frequency conversion value, and θ represents the beam elevation angle.

[0047] Multiply the beam coordinate vector by the beam frequency adjustment value to obtain the beam phase shift value. In an embodiment of the present application, the beam phase shift value characterizes the theoretical phase difference of each array element relative to the coordinate origin in the phased array local coordinate system. During the calculation process of the beam phase shift value, only multiplication and addition operations are involved. At this time, the advantage of parallel operation of the control device (such as FPGA) can be fully utilized, and the pipeline method can be used for fast operation to complete the phase control of the antenna beam.

[0048] In an embodiment of the present application, if the trigonometric function values of the beam azimuth angle include the sine value of the beam azimuth angle and the cosine value of the beam azimuth angle, and the quantized coordinate values of the array antenna include the quantized coordinate values of the array antenna on the first preset coordinate axis and the quantized coordinate values of the array antenna on the second preset coordinate axis, then the process of multiplying the trigonometric function values of the beam azimuth angle by the quantized coordinate values of the array antenna to obtain the beam coordinate vector includes:

[0049] Multiply the sine value of the beam azimuth angle by the quantized coordinate value of the array antenna on the second preset coordinate axis to obtain the first beam coordinate sub-vector. In an embodiment of the present application, the second preset coordinate axis is the y-axis in the phased array local coordinate system, and the calculation formula of the first beam coordinate sub-vector is as follows:

[0050]

[0051] Wherein, y1 represents the first beam coordinate sub-vector, dy represents the quantized coordinate value of the array antenna on the second preset coordinate axis, represents the beam azimuth angle, represents the sine value of the beam azimuth angle.

[0052] Multiply the cosine value of the beam azimuth angle by the quantized coordinate value of the array antenna on the first preset coordinate axis to obtain the second beam coordinate sub-vector. In an embodiment of the present application, the first preset coordinate axis is the x-axis in the phased array local coordinate system, and the calculation formula of the second beam coordinate sub-vector is as follows:

[0053]

[0054] Wherein, x1 represents the first beam coordinate sub-vector, dx represents the quantized coordinate value of the array antenna on the first preset coordinate axis, represents the beam azimuth angle, represents the cosine value of the beam azimuth angle.

[0055] Take the sum of the first beam coordinate sub-vector and the second beam coordinate sub-vector as the beam coordinate vector. In an embodiment of the present application, the calculation formula of the beam coordinate vector is as follows:

[0056] XY = x1 + y1 Equation (4)

[0057] Wherein, XY represents the beam coordinate vector, x1 represents the first beam coordinate sub-vector, and y1 represents the first beam coordinate sub-vector.

[0058] In an embodiment of the present application, the process of converting the beam correction phase shift value into a balanced vector signal includes:

[0059] Obtain the in-phase component, the total in-phase coefficient, the quadrature component, and the total quadrature coefficient of the beam correction phase shift value. In an embodiment of the present application, the in-phase component data, the total in-phase coefficient data, the quadrature component data, and the total quadrature coefficient data are all pre-stored in a flash memory or other storage device. After obtaining the beam correction phase shift value, the beam correction phase shift value is used as a look-up table address to query and obtain the in-phase component, the quadrature component, the total in-phase coefficient, and the total quadrature coefficient. The in-phase component data, the total in-phase coefficient data, the quadrature component data, and the total quadrature coefficient data can all be calculated according to the model of the balanced vector modulator (VM) before calculating the beam correction phase shift value.

[0060] Take the difference between the total in-phase coefficient and the in-phase component as the in-phase complementary component; take the difference between the total quadrature coefficient and the quadrature component as the quadrature complementary component. In an embodiment of the present application, the sum of the in-phase component and the in-phase complementary component is the total in-phase coefficient, the sum of the quadrature component and the quadrature complementary component is the total quadrature coefficient, and the total in-phase coefficient and the total quadrature coefficient are determined according to the model of the balanced vector modulator (VM), etc.

[0061] Take the in-phase component, the in-phase complementary component, the quadrature component, and the quadrature complementary component as the balanced vector signal. In an embodiment of the present application, by using the balanced vector signal for antenna beam control, it has the advantages of more accurate amplitude and phase modulation under the same voltage control and a wider bandwidth.

[0062] In an embodiment of the present application, the process of using the balanced vector signal for antenna beam control includes:

[0063] Perform digital-to-analog conversion on the balanced vector signal to obtain an analog vector signal. In an embodiment of the present application, the process of performing digital-to-analog conversion on the balanced vector signal is implemented by a digital-to-analog converter (DAC), etc.

[0064] Determine the amplitude and phase of the antenna beam through the analog vector signal, and control the antenna beam with the amplitude and phase. In an embodiment of the present application, each antenna beam has a corresponding analog vector signal, and each antenna beam performs amplitude and phase control according to the corresponding analog vector signal. The process of determining the amplitude and phase of the antenna beam through the analog vector signal is carried out by a balanced vector modulator, that is, the analog vector signal is input into the balanced vector modulator, and the balanced vector modulator converts the analog vector signal into the amplitude and phase of the antenna beam.

[0065] In an embodiment of the present application, before obtaining the amplitude-phase error value between array antenna channels, the method further includes:

[0066] Obtain a first check value, which is obtained by performing an exclusive OR operation on the pre-stored amplitude-phase error value. In an embodiment of the present application, the process of performing the exclusive OR operation on the pre-stored amplitude-phase error value can be carried out before storing the pre-stored amplitude-phase error value. After obtaining the first check value, the pre-stored amplitude-phase error value and the first check value are stored in a flash memory or other storage device; the process of performing the exclusive OR operation on the pre-stored amplitude-phase error value can be carried out after storing the pre-stored amplitude-phase error value in the flash memory or other storage device, and the first check value is also stored in the flash memory or other storage device.

[0067] Read the pre-stored amplitude-phase error value, and perform an exclusive OR check on the read amplitude-phase error value to obtain a second check value. In an embodiment of the present application, the process of performing the exclusive OR check on the read amplitude-phase error value is the same as the process of performing the exclusive OR operation on the pre-stored amplitude-phase error value, and specific limitations are not provided here.

[0068] If the first check value is the same as the second check value, the pre-stored amplitude-phase error value is used as the amplitude-phase error value between the array antenna channels. In an embodiment of the present application, if the first check value is the same as the second check value, it indicates that the pre-stored amplitude-phase error value is consistent with the read amplitude-phase error value, and there is no error or loss in the pre-stored amplitude-phase error value.

[0069] If the first check value is different from the second check value, an alarm is given and obtaining the amplitude-phase error value is prohibited. In an embodiment of the present application, if the first check value is different from the second check value, it indicates that the pre-stored amplitude-phase error value is inconsistent with the read amplitude-phase error value, and there is an error or loss in the pre-stored amplitude-phase error value. An alarm prompt is given, and the correctness of the pre-stored amplitude-phase error value is ensured by comparing the first check value with the second check value.

[0070] Figure 3 It is a flowchart of a phased array antenna beam control method shown in another exemplary embodiment of the present application, as Figure 3 shown, the process of the phased array antenna beam control includes: (1) The wave control system receives the beam control instruction information from the host computer, and the beam control instruction information includes the beam pointing angle beam frequency data f and other information. Among them, the beam pointing angle includes: the beam elevation angle θ, the beam azimuth angle (2) The wave control system uses the beam elevation angle θ as the look-up address to query the trigonometric function value of the beam elevation angle from the trigonometric function table, and uses the beam azimuth angle as the look-up address to query the sine value of the beam azimuth angle from the trigonometric function table, and uses the beam azimuth angle The cosine value of the beam azimuth angle is obtained by querying from a trigonometric function table using the look-up table address. The frequency conversion value is obtained by querying from a frequency data table using the beam frequency data f as the look-up table address. The beam system acquires the quantized coordinate values of the array antenna on the first preset coordinate axis and the quantized coordinate values of the array antenna on the second preset coordinate axis, and multiplies the sine value of the beam azimuth angle by the quantized coordinate values of the array antenna on the second preset coordinate axis to obtain the first beam coordinate sub-vector; multiplies the cosine value of the beam azimuth angle by the quantized coordinate values of the array antenna on the first preset coordinate axis to obtain the second beam coordinate sub-vector; (3) takes the sum of the first beam coordinate sub-vector and the second beam coordinate sub-vector as the beam coordinate vector; multiplies the trigonometric function value of the beam elevation angle by the frequency conversion value to obtain the beam frequency adjustment value; (4) multiplies the beam coordinate vector by the beam frequency adjustment value to obtain the beam phase shift value; (5) adds the beam phase shift value and the amplitude-phase error data to obtain the beam correction phase shift value; the amplitude-phase error data is stored in a compensation data table, and this amplitude-phase error data can be obtained through an antenna calibration method and stored after quantization; (6) performs digital-to-analog conversion control on the beam correction phase shift value to obtain a balanced vector signal, inputs the balanced vector signal into a digital-to-analog conversion chip for digital-to-analog conversion, and inputs the signal after digital-to-analog conversion into a balanced vector modulator for phase distribution control of the antenna beam.

[0071] In an embodiment of the present application, since in actual work, the scanning angle range and the scanning angle step parameter of the wave control system are known, the trigonometric function values of the beam pointing angle are calculated in advance according to the known parameters, quantized, and stored in the storage chip (such as FLASH) of the wave control system. When the amount of stored data is large, a storage verification system is used to perform consistency verification on the stored data to ensure the correctness of the stored data. In addition, in order to save storage resources, the mutual relationship of trigonometric functions can be fully utilized to only store the angle values in the first quadrant. The frequency data table stores the frequency conversion values. The dx coordinate table stores the quantized coordinate values of the array antenna on the first preset coordinate axis, and the dy coordinate table stores the quantized coordinate values of the array antenna on the second preset coordinate axis. The trigonometric function table stores the trigonometric function values of the beam pointing angle.

[0072] In some embodiments of the present application, the compensation data table stores the inherent amplitude-phase error data between the array antenna channels. The inherent amplitude-phase error data between the array antenna channels can be obtained through the antenna calibration method, quantified, and then stored. Due to the large scale of the antenna array and the large amount of compensation data, higher requirements are imposed on the storage of the inherent amplitude-phase error data. Therefore, a storage verification system is designed to perform consistency verification on the stored data. The process of performing consistency verification on the stored data through the storage verification system includes: storing the pre-stored amplitude-phase error value and the first verification value obtained by performing an exclusive OR operation on the pre-stored amplitude-phase error value into the storage chip. After the product is powered on, the first verification value and the pre-stored amplitude-phase error value are read out, an exclusive OR verification is performed on the read amplitude-phase error value to obtain the second verification value, and the first verification value and the second verification value are compared. If the first verification value and the second verification value are compared and are consistent, it is determined that there is no error in the data storage. The correctness of the read amplitude-phase error value is ensured through the storage verification system.

[0073] It can be seen from Figure 2 that after obtaining the quantized coordinate values of the array antenna, the amplitude-phase error values between the array antenna channels, and the trigonometric function values of the beam pointing angle through table lookup, the calculation process of the entire beam correction phase shift value only remains multiplication and addition operations.

[0077] The following introduces the device embodiments of the present application, which can be used to execute the phased array antenna beam control method in the above embodiments of the present application. For the details not disclosed in the device embodiments of the present application, please refer to the embodiments of the phased array antenna beam control method above of the present application.

[0078] Figure 5 The block diagram of the phased array antenna beam control device suitable for implementing the embodiments of the present application is shown. This device can be applied to Figure 1 the shown implementation environment and is specifically configured in the control device 102. This device can also be applicable to other exemplary implementation environments and is specifically configured in other devices. The implementation environment applicable to this device is not limited in this embodiment.

[0079] As Figure 5 shown, the exemplary phased array antenna beam control device includes:

[0080] The information acquisition module 501 is used to obtain beam control instruction information, array antenna quantization coordinate values, and amplitude-phase error values between array antenna channels.

[0081] The phase shift value calculation module 502 is used to calculate the beam phase shift value according to the beam pointing angle, beam frequency, and array antenna quantization coordinate values; add the beam phase shift value and the amplitude-phase error data to obtain the beam correction phase shift value.

[0082] The beam control module 503 is used to convert the beam correction phase shift value into a balanced vector signal to perform antenna beam control through the balanced vector signal.

[0083] In an embodiment of the present application, the beam control instruction information includes a beam pointing angle and a beam frequency. The beam pointing angle is an angle in the phased array local coordinate system, and the beam pointing angle is obtained by rotating the angle in the geodetic coordinate system through the Euler coordinate rotation formula; the array antenna quantization coordinate values include the array antenna quantization coordinate values of the first preset coordinate axis and the array antenna quantization coordinate values of the second preset coordinate axis. The first preset coordinate axis is the x-axis in the phased array local coordinate system, and the second preset coordinate axis is the y-axis in the phased array local coordinate system, etc. The amplitude-phase error value between array antenna channels is determined when calibrating the array antenna, and each array antenna has an amplitude-phase error value. The array antenna quantization coordinate values and the amplitude-phase error values between array antenna channels are pre-stored in a flash memory or other memory, which is convenient for directly obtaining them by reading when calculating the beam correction phase shift value.

[0084] In an embodiment of the present application, the beam pointing angle includes a beam elevation angle and a beam azimuth angle. The process of calculating the beam phase shift value according to the beam pointing angle, the beam frequency, and the array antenna quantization coordinate values includes: obtaining the trigonometric function value of the beam elevation angle, the trigonometric function value of the beam azimuth angle, and the frequency conversion value of the beam frequency; determining the beam coordinate vector based on the trigonometric function value of the beam azimuth angle and the array antenna quantization coordinate values; multiplying the trigonometric function value of the beam elevation angle by the frequency conversion value to obtain the beam frequency adjustment value; multiplying the beam coordinate vector by the beam frequency adjustment value to obtain the beam phase shift value. In a flash memory or other memory, the trigonometric function values of each elevation angle, the trigonometric function values of each azimuth angle, and the frequency conversion values of each frequency are pre-stored. After obtaining the beam elevation angle, the beam azimuth angle, and the beam frequency, the beam elevation angle, the beam azimuth angle, and the beam frequency are respectively used as the look-up table addresses, and the trigonometric function value of the beam elevation angle is obtained by looking up from the trigonometric function values of each elevation angle, the frequency conversion value of the beam frequency is obtained by looking up from the frequency conversion values of each frequency, and the trigonometric function value of the beam azimuth angle is obtained by looking up from the trigonometric function values of each azimuth angle, which makes up for the disadvantage that the control device (such as an FPGA) cannot perform floating-point operations in real time, and is convenient for the control device to quickly calculate the beam phase shift value according to the beam pointing angle, the beam frequency, and the array antenna quantization coordinate values.

[0085] In an embodiment of the present application, by obtaining the beam control instruction information, the array antenna quantization coordinate values, and the amplitude-phase error values between array antenna channels, calculating the beam phase shift value according to the beam pointing angle, the beam frequency, and the array antenna quantization coordinate values, adding the beam phase shift value and the amplitude-phase error data to obtain the beam correction phase shift value, and converting the beam correction phase shift value into a balanced vector signal to perform antenna beam control through the balanced vector signal. The above process has the advantages of more accurate amplitude and phase modulation and wider bandwidth under the same voltage control when using the balanced vector signal for antenna beam control.

[0086] In some embodiments of the present application, by means of looking up a table and calculating the beam correction phase shift value by a control device (e.g., FPGA), the defect that the control device does not have a floating-point operation function is made up for, the calculation rate of the control device (e.g., FPGA) for calculating the beam correction phase shift value is improved, and the flexibility of the control device (e.g., FPGA) for calculating the beam correction phase shift value is maintained.

[0087] In an embodiment of the present application, the phased array antenna beam control device further includes:

[0088] An information storage module, configured to pre-store the quantized coordinate values of the array antenna, the amplitude-phase error values, and the trigonometric function values of the beam pointing angles.

[0089] In an embodiment of the present application, the information storage module may be a flash memory or other memories, etc. The information storage module is further configured to store in-phase component data, in-phase component total coefficient data, quadrature component data, quadrature component total coefficient data, and a first check value, etc. By cooperating with the control device (such as, FPGA), the combination of the look-up table method and the real-time calculation method is realized, the defect that the FPGA cannot perform trigonometric function and division operations is avoided, the operation resources of the FPGA are saved, the real-time performance of beamforming is improved, and it has the characteristics of high speed, high reliability, flexible control, and easy expansion.

Among them, the FPGA includes a beam control timing control unit, a communication processing unit, a beam control code calculation and processing unit, a FLASH control interface unit, and a DAC control unit. The host computer is used to send beam control instruction information to the communication processing unit. The communication processing unit is used to perform data parsing, decryption, decompression, etc. on the beam control instruction information, and forward it to the beam control code calculation and processing unit. The beam control code calculation and processing unit is used to obtain the trigonometric function values of the beam pointing angle, the frequency conversion values of the beam frequency, the amplitude-phase error values between the array antenna channels, and the quantization coordinate values of the array antenna stored in the FLASH through the FLASH control interface unit, and calculate the beam correction phase shift value according to the trigonometric function values of the beam pointing angle, the frequency conversion values of the beam frequency, the amplitude-phase error values between the array antenna channels, and the quantization coordinate values of the array antenna. The DAC control unit is used to convert the beam correction phase shift value into a balanced vector signal.
