Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of beam control, and particularly to a beam control method, an apparatus, and a readable storage medium. Background Art

[0002] A Synthetic Aperture Radar (SAR) system is usually used to image ground fixed-scene targets and is an active earth observation system. The beam control system is an important part of the SAR and is used to calculate the wave control parameters required for the phase shifters corresponding to each antenna element in the antenna array to achieve the scanning control of the antenna beam.

[0003] Generally, the methods for the beam control system to calculate the wave control parameters mainly include the real-time look-up table method or the real-time calculation method. However, the real-time look-up table method is limited by the memory storage space and is only applicable to systems with fewer wave control units and a small variation range of frequency points and beam pointing angles; the real-time calculation method uses a digital signal processor (DSP) chip to serially execute instructions and is also applicable to systems with fewer wave control units. Therefore, the existing real-time look-up table method and real-time calculation method cannot meet the increasing demand for the scale of the antenna wave control units in the SAR system. Summary of the Invention

[0004] Embodiments of the present disclosure are expected to provide a beam control method, an apparatus, and a readable storage medium that can calculate and obtain wave control parameters in parallel, improving the operation efficiency.

[0005] The technical solution of the embodiments of the present disclosure is implemented as follows:

The beam control method is applied to a wave control system and includes: a beam controller obtains wave control data; divides the wave control data into at least two groups according to the antenna position data of the wave control data; calculates the wave control data of each group in parallel to obtain wave control parameters corresponding to the wave control data of each group; and an antenna connected to the backend of the beam controller performs beam control based on the wave control parameters.

[0027] In order to make the objectives, technical solutions, and advantages of the exemplary embodiments of the present disclosure clearer, the exemplary embodiments of the present disclosure will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limitations on the exemplary embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the exemplary embodiments of the present disclosure.

[0028] Figure 1 Schematic diagram of the implementation process of a beam control method provided in the exemplary embodiments of the present disclosure. As Figure 1 shown, the beam control system implementing the beam control method includes:

[0029] S101. The beam controller acquires wave control data;

[0030] S102. According to the antenna position data of the wave control data, the wave control data is divided into at least two groups;

[0031] S103. Calculate the wave control data of each group in parallel to obtain the wave control parameters corresponding to the wave control data of each group;

[0032] S104. The antenna connected to the rear end of the beam controller performs beam control based on the wave control parameters.

[0033] In the exemplary embodiments of the present disclosure, the beam control system includes a beam controller, which can communicate with the monitoring and calculation module of the SAR system to acquire wave control data, and calculate the wave control parameters in parallel based on the wave control data to achieve beam control.

[0034] Exemplarily, the exemplary embodiments of the present disclosure include, but are not limited to, using a Field Programmable Gate Array (FPGA) as the core processor of the wave control controller to implement parallel calculation.

[0035] In the embodiments of the present disclosure, the beam control system further includes a wave control unit and a transceiver assembly. As Figure 2 shown, the monitoring and calculation module of the SAR system establishes communication with the beam controller. The beam controller corresponds to N wave control units, and each wave control unit corresponds to L transceiver assemblies. After calculating the wave control parameters, the wave control controller sends the wave control parameters to the corresponding wave control unit. The wave control unit distributes and outputs the received wave control parameters as a data interface circuit, so that the antenna can transmit and receive beams according to the parallelly calculated wave control parameters, thereby enabling the transmitting and receiving beams of the antenna to point to the set direction, and at least realizing the direction control of the beam.

[0036] In some embodiments, the wave control parameters may include direction parameters, and the direction parameters can be used to control the direction of the beam. In some other embodiments, the wave control parameters may further include: power parameters, and the power parameters are used to control the transmitting and receiving power of the beam.

[0037] It should be noted that each antenna is connected to a phase shifter. The phase shifter adjusts the phase of the antenna beam through the received wave control parameters. By adjusting the phase, the direction of the beam is changed, so that the antenna beam can be oriented towards the set direction.

[0038] In the embodiments of the present disclosure, in the process of the beam control system controlling the beam, it is necessary to first obtain wave control data. The wave control data includes antenna position data. The antenna position data is used to represent the antenna array number of the antenna array where the wave control unit is located and the wave control unit number of the wave control unit in the antenna array.

[0039] Exemplarily, as Figure 3 shown, the layout of the wave control units connected to the beam controller is a rectangular layout. The X-axis represents the antenna array number of the antenna array where the wave control unit is located, and the antenna array number ranges from array 1 to array M; the Y-axis represents the wave control unit number of the wave control unit in the antenna array, and the wave control unit number ranges from wave control unit number 1 to wave control unit number N. It can be seen along the X-axis direction that the SAR antenna planar array has M antenna arrays in total, and it can be seen along the Y-axis direction that each antenna array in the SAR antenna planar array corresponds to N wave control units, and each wave control unit corresponds to L components. The Figure 3 components therein are transceiver components.

[0040] It can be Figure 3 seen that the antenna position data can be coordinate data composed of the antenna array number and the wave control unit number, and the coordinate data represents the position where the antenna is located. For example, the coordinate data (1, 1) represents the antenna position where the antenna array number is 1 and the wave control unit number is 1; the coordinate data (2, 1) represents the antenna position where the antenna array number is 2 and the wave control unit number is 1.

[0041] In the embodiments of the present disclosure, the wave control data further includes scanning parameters, which are used to characterize the scanning phase of the beam pointing in the SAR antenna coordinate system. The scanning parameters include a first scanning parameter and a second scanning parameter.

[0042] It should be noted that the first scanning parameter includes, but is not limited to, a range-direction scanning parameter, which is at least used to characterize the scanning phase of the beam pointing in the range direction; the second scanning parameter includes, but is not limited to, an azimuth-direction scanning parameter, which is at least used to characterize the scanning phase of the beam pointing in the azimuth direction.

[0043] In the embodiments of the present disclosure, after obtaining the wave control data, the beam controller of the beam control system divides the wave control data into at least two groups according to the antenna position data, specifically, it can be two groups, three groups or more than two groups of wave control data. The amount of data of each group of wave control data after grouping is less than that of all the wave control data before grouping.

[0044] It should be noted that grouping the wave control data according to the antenna position data includes: grouping the wave control data based on the antenna array number in the antenna position data; or, grouping the wave control data based on the wave control unit number in the antenna position data; or, grouping the wave control data based on the antenna array number and the wave control unit number.

[0045] Exemplarily, grouping the wave control data based on the antenna array number includes, but is not limited to, dividing the wave control data with the same antenna array number into one group, or dividing the wave control data with different antenna array numbers into one group.

[0046] In the embodiments of the present disclosure, after grouping, the beam controller of the beam control system calculates each group of wave control data in parallel to obtain the wave control parameters corresponding to each group of wave control data.

[0047] It should be noted that as Figure 3 shown, the antenna position data includes N groups of wave control data. Calculating each group of wave control data in parallel includes: calculating the wave control parameters corresponding to the first group of wave control data in parallel; calculating the wave control parameters corresponding to the second group of wave control data in parallel, and calculating N times until the wave control parameters corresponding to the last group of wave control data are calculated in parallel, then the wave control parameters corresponding to each group of wave control data can be obtained.

[0048] It can be understood that in the embodiments of the present disclosure, the wave control data is first grouped, and then each group of grouped wave control data is calculated in parallel, which can shorten the time for calculating the wave control parameters and improve the operation efficiency.

[0049] In one embodiment, the antenna position data includes: the antenna array number of the antenna array where the wave control unit is located and the wave control unit number of the wave control unit in the antenna array. According to the antenna position data of the wave control data, the wave control data is divided into at least two groups, including:

[0050] Group the wave control data with the same wave control unit number and different antenna array numbers to obtain the grouped wave control data for each group.

[0051] It should be noted that the wave control data with the same wave control unit number and different antenna array numbers are grouped into one group, and the method of calculating the azimuth parameter corresponding to the antenna array number of the wave control data in different groups is the same.

[0052] Exemplarily, as Figure 3 shown, (1, 1), (2, 1), (3, 1) to (M, 1) can be grouped into one group, (1, 2), (2, 2), (3, 2) to (M, 2) can be grouped into one group, and so on, N groups of wave control data can be obtained.

[0053] It can be understood that when calculating the wave control parameters, since the method of calculating the azimuth parameter corresponding to the antenna array number of the wave control data in different groups is the same, the azimuth parameters corresponding to the wave control data of each group can be calculated in parallel, which is convenient for shortening the time to obtain the wave control parameters based on the azimuth parameters and improving the operation efficiency.

[0054] In one embodiment, calculate the wave control data of each group in parallel to obtain the wave control parameters corresponding to the wave control data of each group, including:

[0055] Determine the range direction parameters of the wave control data of each group according to the wave control data of each group;

[0056] Determine the azimuth parameters of the wave control data of each group according to the wave control data of each group;

[0057] Based on the range direction parameters and azimuth parameters, calculate the wave control parameters corresponding to the wave control data of each group in parallel.

[0058] In the embodiments of the present disclosure, the range direction parameters of the wave control data of each group are the range direction wave control codes of the wave control data of each group, and the range direction wave control code is used to adjust the orientation of the beam in the range direction; the azimuth parameters of the wave control data of each group are the azimuth wave control codes of the wave control data of each group, and the azimuth wave control code is used to adjust the orientation of the beam in the azimuth direction.

[0059] It should be noted that the range direction parameters and azimuth parameters can be directly read by using the look-up table method, or can be calculated by using the real-time calculation method. The embodiments of the present disclosure do not limit this here.

[0060] Exemplarily, in the process of calculating the wave control parameters, a wave control parameter calculation model can be used to calculate the wave control data to obtain the wave control parameters. The wave control parameter calculation model (1) can be:

[0061] C = P1 + P2 (1)

[0062] Among them, C is the wave control parameter, P1 is the range parameter, and P2 is the azimuth parameter.

[0063] As can be seen from the above wave control parameter calculation model, before calculating the wave control parameter, it is necessary to first calculate the azimuth parameter and the range parameter, and then determine the corresponding wave control parameter for each group based on the azimuth parameter and the range parameter.

[0064] In one embodiment, the method further includes:

[0065] Before parallel computing the wave control data of each group, obtain the azimuth parameter of the wave control data of each group;

[0066] Store the azimuth parameter of the wave control data of each group.

[0067] It should be noted that the azimuth parameters of the wave control data of each group can be pre-calculated, and the calculated azimuth data of the wave control data of each group are stored. When parallel computing the wave control data of each group, it is not necessary to calculate the azimuth data, but can be directly read through the address decoding method after the beam control system is powered on. In this way, the azimuth parameter can be directly obtained without calculation, which is convenient for quickly calculating the wave control parameter subsequently.

[0068] In one embodiment, obtaining the azimuth parameter of the wave control data of each group includes:

[0069] Obtain the second scan parameter of the wave control data of each group and the antenna array number of the wave control data of each group;

[0070] Determine the azimuth parameter of the wave control data of each group according to the second scan parameter and the antenna array number.

[0071] In the embodiments of the present disclosure, the antenna array numbers in the wave control data of each group are different, and it is necessary to calculate the azimuth parameters of the wave control data of each group in parallel according to the different antenna array numbers and the corresponding second scan parameters in each group.

[0072] Exemplarily, when determining the azimuth parameter of the wave control data of each group, an azimuth calculation model can be used to determine the azimuth parameter of the wave control data of each group. The azimuth calculation model (2) can be:

[0073] P2 = m * ΔP x (2)

[0074] Among them, m is the antenna array number, ΔP x is the second scan parameter, and P2 is the azimuth parameter.

[0075] In one embodiment, determining the azimuth parameter of the wave control data of each group according to the wave control data of each group includes:

[0076] Read the azimuth parameter of the wave control data of each group.

[0077] It should be noted that the azimuth parameters of each group of beam control data are pre-stored. Therefore, when determining the azimuth parameters of each group of beam control data, the azimuth parameters of each group of beam control data can be determined by directly reading. The storage path includes but is not limited to being stored in a read-only memory or a random memory.

[0078] It can be understood that compared with pre-storing all beam control parameters, the embodiments of the present disclosure only store some parameters, reducing the amount of stored data, and thus reducing the storage overhead caused by storing beam control parameters in a large antenna array; compared with real-time serial calculation, directly reading this parameter to calculate the beam control parameters can shorten the time to calculate the beam control parameters and improve the operation efficiency.

[0079] In one embodiment, according to each group of beam control data, determining the range parameters of each group of beam control data includes:

[0080] Reading the first scan parameter;

[0081] According to the first scan parameter, the beam control unit number of each group of beam control data, and the number of transceiver components corresponding to the beam control unit, determining the range parameters of each group of beam control data.

[0082] In the embodiments of the present disclosure, before determining the range parameters of each group of beam control data, the beam controller pre-stores the first scan parameter. This pre-storage can be that the first scan parameter is pre-stored before devices such as base stations are established. In some other embodiments, the first scan parameter can be dynamically updated by communication devices such as base stations at a predetermined period. When calculating the beam control parameters multiple times within a predetermined period, the first scan parameter updated once in a common predetermined period can be shared. In this way, when determining the range parameters of each group of beam control data, the first scan parameter can be directly read without calculation.

[0083] It should be noted that when determining the range parameters of each group of beam control data, a range calculation model can be adopted, and the range parameters of each group of beam control data are determined by multiplying the first scan parameter, the beam control unit number, and the number of transceiver components corresponding to the beam control unit respectively.

[0084] Exemplarily, the range calculation model (3) can be:

[0085] P1 = l * n * ΔP y (3)

[0086] Where n is the beam control unit number, ΔP y is the first scan parameter, P1 is the range parameter, and l is the number of transceiver components corresponding to the beam control unit.

[0087] To facilitate the understanding of the above embodiments, the following exemplary embodiments are provided:

[0088] Assume that the flight direction of the phase center of the SAR antenna is parallel to the ground plane. When the viewing angle is fixed at a certain distance and the azimuth scanning angle changes, the ground track of the beam pointing is parallel to the radar ground track and also parallel to the ground track of the antenna normal. The SAR imaging coordinate system is as Figure 4 shown, where A s is the azimuth scanning angle, R s is the range scanning angle, θ0 is the viewing angle of the antenna normal, and θ is the viewing angle of the antenna beam. It can be known from Figure 4 that the scanning vector of the beam pointing in the SAR antenna coordinate system is (sinA S , cosA S sinR S ).

[0089] The corresponding scanning parameters are respectively given by Equation (4):

[0090]

[0091] where ΔP x is the second scanning parameter, ΔP y is the first scanning parameter, D x is the azimuth element spacing, D y is the range element spacing, and λ is the wavelength of the center frequency.

[0092] It should be noted that in the SAR imaging coordinate system, the positive direction reference of the SAR antenna beam pointing is the antenna array body coordinate system. The +Z direction is the direction of the satellite towards the ground, the positive azimuth direction is the +X direction (satellite flight direction), and the positive range direction is the +Y direction. Among them, the X direction, Y direction, and Z direction all conform to the definition of the standard right-handed coordinate system, that is, the direction obtained by the vector multiplication of the X direction and the Y direction is the Z direction. That is to say, ΔP x is the azimuth scanning parameter, and ΔP y is the range scanning parameter.

[0093] Since the current azimuth scanning angle A s of the SAR system is only in the range from +2.5° to -2.5°, therefore, when taking the cosine value of the azimuth scanning angle, cosA S can be regarded as 1. Based on this, Equation (4) can be transformed into Equation (5), and Equation (5) is as follows:

[0094]

[0095] Through formula (5), the beam controller of the beam control system can calculate and store the first scanning parameter and the second scanning parameter. When calculating the wave control parameters in the beam control system, they can be directly read for calculation.

[0096] Through the azimuth calculation model and the range calculation model, the wave control parameter calculation model can be transformed to obtain the transformed wave control parameter calculation model (6). The transformed wave control parameter calculation model (6) can be:

[0097] c(m,n,l) = m * ΔP x + l * n * ΔP y (6)

[0098] The calculation of the wave control parameters can refer to the transformed wave control parameter calculation model. Specifically, first determine the azimuth parameters through the azimuth calculation model, then determine the range parameters through the range calculation model, and finally determine the wave control parameters through the azimuth parameters and the range parameters.

[0099] As Figure 5 shown, based on this transformed wave control parameter calculation model, the real-time calculation method is serial calculation. First, calculate from (1,1) to (1,N), which is calculated N times; then calculate from (2,1) to (2,N), which is calculated N times; and so on, until calculating from (M,1) to (M,N). Such serial calculation requires M * N times of calculation. It can be seen that this real-time calculation method is not applicable to the beam control system with a large number of wave control units.

[0100] Based on this, by analyzing the antenna position data, it can be known that for the set of wave control data of (1,1), (2,1), (3,1) to (M,1), their antenna array numbers are different and the wave control unit numbers are the same; compared with the set of wave control data of (1,2), (2,2), (3,2) to (M,2) and the set of wave control data of (1,3), (2,3), (3,3) to (M,3), the antenna array numbers of these three sets of wave control data are the same, and the values of the wave control unit numbers increase by 1. Therefore, the wave control data with different antenna array numbers and the same wave control unit number can be grouped into one group to obtain each group of grouped wave control data.

[0101] In the SAR system, the antenna array number corresponding to the antenna is much smaller than the product of the wave control unit number and the number of transceiver modules. Also, the antenna array numbers in each group of wave control data after grouping are the same. Therefore, the azimuth parameters can be calculated in advance based on the antenna array number and the first scanning parameter and stored in the beam control system. Then, during the calculation of the wave control parameters corresponding to each group of wave control data, the azimuth parameters can be directly read first, and then the range parameters can be calculated based on the group number, the number of transceiver modules, and the second scanning parameter corresponding to each group of wave control data. In this way, for the group of wave control data from (1, 1), (2, 1), (3, 1) to (M, 1), the wave control parameters corresponding to this group of wave control data can be directly calculated in parallel, and the wave control parameters corresponding to all groups of wave control data can be calculated in N times.

[0102] As Figure 6 shown, the process of calculating the wave control parameters corresponding to each group of wave control data in parallel is as follows:

[0103] (1) Read the first group of azimuth parameters and the first scanning parameter of the first group of wave control data from (1, 1), (2, 1), (3, 1) to (M, 1); determine the first group of range parameters based on the first scanning parameter, the first group of wave control unit numbers, and the number of transceiver modules; input the first group of azimuth parameters and the first group of range parameters into the calculation module of the beam controller respectively to determine the wave control parameters of all transceiver modules in the M wave control units of the first group, that is, obtain the wave control parameters corresponding to the first group of wave control data through the first parallel calculation;

[0104] (2) Read the second group of azimuth parameters and the first scanning parameter of the second group of wave control data from (1, 2), (2, 2), (3, 2) to (M, 2); determine the second group of range parameters based on the first scanning parameter, the second group of wave control unit numbers, and the number of transceiver modules; input the second group of azimuth parameters and the second group of range parameters into the calculation module of the beam controller respectively to determine the wave control parameters of all transceiver modules in the M wave control units of the second group, that is, obtain the wave control parameters corresponding to the second group of wave control data through the second parallel calculation;

[0105] (3) And so on, until reading the Nth group of azimuth parameters and the first scanning parameter of the Nth group of wave control data from (1, N), (2, N), (3, N) to (M, N), determine the Nth group of range parameters based on the first scanning parameter, the Nth group of wave control unit numbers, and the number of transceiver modules; input the Nth group of azimuth parameters and the Nth group of range parameters into the calculation module of the beam controller respectively to determine the wave control parameters of all transceiver modules in the M wave control units of the Nth group, that is, obtain the wave control parameters corresponding to the Nth group of wave control data through the Nth parallel calculation. In this way, the wave control parameters corresponding to each group of wave control data can be calculated.

[0106] It can be understood that, on the one hand, compared with the existing method of calculating and storing the beam parameters corresponding to the beam pointing angles of all frequency points, that is, the real-time look-up table method, since only partial data is stored in the embodiments of the present disclosure, the possibility of being restricted by the storage space is relatively small, and it can be applied to large-scale beam control systems with more wave control units and transceiver components. On the other hand, compared with the existing serial real-time calculation method, in the embodiments of the present disclosure, some data is obtained by directly reading the memory, and the other part of the data is obtained by parallel calculation. Thus, the time required to obtain the wave control parameters in the embodiments of the present disclosure is at least 1 / M of the serial real-time calculation, which can significantly shorten the time for obtaining the wave control parameters and improve the operation efficiency.
