Description

Technical Field

[0001] This application relates to the field of phased array antenna technology, and in particular to a method, apparatus, equipment and medium for phase calculation of a triangular array phased array antenna. Background Technology

[0002] Phase calculation for large-scale phased array antennas is time-consuming. Higher-frequency processors are typically used to reduce this time, or multi-channel parallel computing is employed to accelerate the calculation. Implementation using programmable gate arrays (FPGAs) usually requires significant resources, which increases the requirements for FPGA chip selection.

[0003] For triangular phased array antennas, since the array elements in adjacent rows or columns of the triangular array are staggered, in the actual calculation process, the N×M array surface is expanded to a 2N×M array surface. After calculation according to the conventional square array, the phase of the actual array element of the triangular array is extracted according to the sequence number for use. This leads to an expansion of the calculation workload and increases the resource consumption for phase solution of large-scale phased arrays.

[0004] Therefore, a technical solution is urgently needed to address the problem of excessive computational resource consumption when performing phase calculations for large-scale triangular phased array antennas. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] In one embodiment, such as Figure 1 As shown, a method for phase calculation of a triangular phased array antenna is provided, including the following steps: Step 201: Receive the azimuth and off-axis angles of the received beam, and calculate the sine and cosine values ​​corresponding to the azimuth and off-axis angles of the received beam.

[0022] Step 202: Calculate the unit phase difference on the X-axis and the unit phase difference on the Y-axis of the triangular array phased array antenna based on the sine and cosine values ​​corresponding to the azimuth and off-axis angles.

[0023] Step 203: Calculate the phase of the X-axis reference array element and the phase of the Y-axis reference array element based on the X-axis unit phase difference and the Y-axis unit phase difference, respectively; and divide the triangular array phased array antennas into the first subarray set according to the number of rows or columns being odd, and divide them into the second subarray set according to the number of rows or columns being even.

[0024] It should be noted that the triangular array phased array antennas are divided into the first subarray set according to whether the number of rows or columns is odd, and the second subarray set according to whether the number of rows or columns is even. Specifically, the triangular array phased array antennas can be divided into the first subarray set and the second subarray set according to the parity of the number of rows, or the triangular array phased array antennas can be divided into the first subarray set and the second subarray set according to the parity of the number of columns.

[0025] Step 204: For each element in the first subarray set, add the phase of each element in the X-axis reference axis to the phase of the m-th element in the Y-axis. Iterate through the phases of the Y-axis reference axis elements to calculate all phases in the first subarray set, where m∈[1,…,M] and M is the number of elements in the Y-axis.

[0026] Step 205: Add the phase of each subarray element in the first subarray set to the unit phase difference on the X-axis and the unit phase difference on the Y-axis to obtain the phase of each subarray in the second subarray set with an even number of rows, thus obtaining all the phases of the second subarray set.

[0027] In the aforementioned phase calculation method for triangular phased array antennas, the triangular phased array antenna is divided into a first subarray set and a second subarray set based on whether the number of rows is odd or even. After calculating all the phases of the first subarray set, all the phases of the second subarray set can be obtained by adding the unit phase difference along the X-axis and the unit phase difference along the Y-axis to the phase of each array element. This design significantly reduces the amount of data stored and minimizes the use of multiplier resources.

[0028] In one embodiment, step 202, calculating the X-axis unit phase difference and Y-axis unit phase difference of the triangular phased array based on the sine and cosine values ​​corresponding to the azimuth and off-axis angles, includes: Calculate the unit phase difference along the X-axis and the unit phase difference along the Y-axis of the triangular phased array antenna based on the sine and cosine values ​​corresponding to the azimuth and off-axis angles:

[0029]

[0030] in, The phase difference is expressed as a unit on the X-axis. The phase difference is expressed as a unit along the Y-axis. Half wavelength; The spacing between array elements; It is the off-axis angle; It is the azimuth angle.

[0031] In one embodiment, step 203, calculating the X-axis reference array element phase and the Y-axis reference array element phase based on the X-axis unit phase difference and the Y-axis unit phase difference respectively, includes: The phase of each element along the X-axis reference axis and the phase of each element along the Y-axis reference axis are calculated based on the unit phase difference along the X-axis and the unit phase difference along the Y-axis, respectively.

[0032]

[0033]

[0034]

[0035] in, The phase of the X-axis reference array element; The phase of the Y-axis reference axis array element; For the X-axis reference axis n The phase of each array element; Y-axis reference axis m The phase of each array element; N This represents the number of array elements along the X-axis.

[0036] Reference Figure 2 For typical triangular array phase calculation, each interval in the triangular array needs to be filled with virtual array elements, and then the phase calculation is performed according to the conventional square array phase calculation method. The obtained phase is then extracted according to the channel number to obtain the phase of the triangular array. Figure 2As can be seen, the gray solid circle represents the actual triangular array elements, and the white dashed circle represents the virtual array elements. For an N×M triangular array surface, after adding virtual array elements, the array surface size expands to 2N×M.

[0037] After employing the method described in this invention, the array surface of the triangular formation is decomposed into two types of subarray sets (i.e., the first subarray set and the second subarray set). It should be noted that the number of the first and second subarrays needs to be determined based on the number of Y-axis array elements. When the number of Y-axis array elements is even, the number of array elements in the first and second subarrays is equal. When the number of Y-axis array elements is odd, the first subarray has X more array elements than the second subarray. (Refer to...) Figure 3 Dark-colored array elements are the first subarray elements, and light-colored array elements are the second subarray elements. After calculating the total number of array elements in the first subarray set, we only need to add the phase of each subarray element in the first subarray set to the unit phase difference on the X-axis and the unit phase difference on the Y-axis to obtain the phase of each subarray in the second subarray set with an even number of rows, and then we can obtain all the phases of the second subarray set.

[0038] The resource consumption of traditional virtual array filling methods and the method described in this invention was compared, and the results are shown in Table 1.

[0039] Table 1. Comparison of resource consumption for different methods

[0040] Where N is the number of X-axis array elements and M is the number of Y-axis array elements. · This indicates rounding up. It can be seen that the present invention requires fewer resources than the virtual array element filling method in terms of both the number of multiplications and additions, demonstrating that the present invention can significantly reduce data storage requirements.
