[0050] Step S2, according to the design input, on the computer, through Figure 3 the self-built optimization algorithm to obtain N el ×N az phase shift values γ m,n .

[0051] The calculation process in the self-built optimization algorithm includes:

[0052] Taking the number of antenna units N el along the elevation direction, the spacing d el between the antenna units along the elevation direction, and the beam width index θ BW,std in the wide beam working mode as inputs, the intelligent optimization algorithm is used to obtain the phase shift values ψ m of the one-dimensional linear array along the elevation direction, where m = 1, 2, …, N el In this embodiment, the intelligent optimization algorithm uses one of the particle swarm algorithm, the genetic algorithm, etc.

[0062] The control over whether each channel in the array is open or closed is controlled by switch A. m,n Indicate, and will all A m,n Both are set to 1. The variable f is the operating frequency, and c is the speed of light. |·| represents the absolute value operation. e (·) This represents an exponential function, where i represents the imaginary unit. Different azimuth angles are obtained...

BW .

[0063] S4, Combination and θ BW,std Verify whether the array power gain meets the preset requirements. If it does, then the N...el ×N az Phase shift value γ m,n The corresponding L-band wide-beam high-power array is the design result; otherwise, the design input is re-imported into the self-built optimization algorithm for optimization until the array power gain meets the preset requirements.

[0064] If step S3 yields the aforementioned result Not less than the aforementioned And simultaneously satisfy the calculated θ mentioned above BW Not less than the aforementioned θ BW,std Then, calculate the number of antenna elements along the azimuth direction for a conventional equal-amplitude co-directional array as N. az The number of antenna elements along the elevation direction is N el The spacing between antenna elements along the azimuth direction is d. az Antenna element spacing d along the elevation direction el C is the control switch that controls whether each channel in the array is open or closed. m,n Under the condition that the operating frequency remains f, the traditional equal-amplitude co-directional array at different azimuth angles Array power gain at different pitch angles θ The calculation formula is as follows:

[0065]

[0066] In a traditional equal-amplitude co-directional array, the activation or deactivation of each channel is controlled by switch C. m,n It means that C m,n It can be either 1 or 0. The variable f is the operating frequency, and c is the speed of light. |·| represents the absolute value operation. e (·) This represents an exponential function, where i represents the imaginary unit. Different azimuth angles are obtained... Array power gain at different pitch angles θ Then, find The maximum value H max ,as well as equals H max The corresponding pitch angle and azimuth Then at the pitch angle and azimuth Find all the satisfactions around Corresponding azimuth angle and pitch angle θ l , The coverage area is the azimuth half-power beamwidth of a traditional equal-amplitude co-directional array. θ l The coverage area is the actual elevation half-power beamwidth of a conventional equal-amplitude co-directional array. like Less than or Less than θ BW,std Then adjust C m,n until satisfied Not less than and Not less than θ BW,std Then record H max .

[0067] If the maximum value G of the array power gain in wide-beam mode obtained in step S3 is... max The maximum array power gain H obtained in step S4 is greater than the maximum value of the array power gain in the traditional equal-amplitude co-directional wide-beam mode. max Then the N obtained in step S2 el ×N az Phase shift value γ m,n The design result for the corresponding L-band wide-beam high-power array is output. Otherwise, the design input is re-imported into the self-built optimization algorithm (i.e., return to step S2) and the subsequent steps are executed until both conditions are met. Not less than the half-power beamwidth specification in wide beam operating mode θ BW Not less than the pitch half-power beamwidth specification θ in wide-beam operating mode BW,std Maximum power gain of array G max Greater than the maximum power gain H of a traditional equal-amplitude co-directional array max Then, the N obtained in step S2 el ×N az Phase shift value γ m,n The design results of the corresponding L-band wide-beam high-power array are output.

[0068] This embodiment also provides a comparison of beamwidth and array power gain. Figure 4 In the diagram, the white area represents the half-power beamwidth coverage of a traditional equal-amplitude co-directional array. It can be seen that a traditional equal-amplitude co-directional array can achieve 20°×20° (azimuth×elevation) beamwidth coverage. However, calculations reveal that to achieve 20°×20° wide beamwidth coverage, a portion of the power amplifier in a traditional equal-amplitude co-directional array needs to be turned off, resulting in a maximum array power gain H. max Only 24.1dB, then Figure 4 The white area represents the region where the power gain of a traditional equal-amplitude, co-directional array is greater than or equal to 21.1 dB. Figure 6 In the diagram, the white area represents the half-power beamwidth coverage of the array using this invention. It can be seen that this invention can also achieve 20° × 20° (azimuth × elevation) beam coverage. Calculations show that the maximum array power gain G using this invention is... maxis 34.8dB, then Figure 6 The white area in the figure is the area where the array power gain of the array surface of the application is greater than 31.8dB. Therefore, the array power gain of the array surface of the application is 10.7dB greater than the array power gain of the conventional equal-amplitude omnidirectional array, and the effective distance in the battlefield is longer. Figure 5 is a comparison chart of the array power gains of the conventional equal-amplitude omnidirectional array and the array surface of the application at different azimuth angles when the elevation angle is 0, i.e., a comparison chart of H(0, θ) and G(0, θ). As can be seen from the comparison chart of H(0, θ) and G(0, θ), when the azimuth angle is 0, the array power gain of the array surface of the application is obviously higher than the array power gain of the conventional equal-amplitude omnidirectional array, and the calculation result of the array power gain reflects the advantages of the application. Figure 7 is a comparison chart of the array power gains of the conventional equal-amplitude omnidirectional array and the array surface of the application at different elevation angles when the azimuth angle is 0, i.e., a comparison chart of H(0, θ) and G(0, θ), as can be seen from the comparison chart of H(0, θ) and G(0, θ), when the azimuth angle is 0, the array power gain of the array surface of the application is obviously higher than the array power gain of the conventional equal-amplitude omnidirectional array, and the calculation result of the array power gain reflects the advantages of the application.
