[0046] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this invention.

[0047] It should be noted that in the description of this application, "multiple" is understood as "at least two". "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A connected to B can represent: A and B directly connected, or A and B connected through C. Furthermore, in the description of this application, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0048] See Figure 1 As shown, this is a schematic diagram of a possible application scenario provided by an embodiment of this application. The application scenario includes three positioning base stations R1, R2, and R3. In this embodiment, the positioning card is connected to the receiving antenna, and the distance between the positioning card and the transmitting antenna of each positioning base station is calculated according to ultra-wideband technology (UWB, such as TDOA, TOA, TOF, etc.). The specific position of the receiving antenna is then calculated using the least squares method. For example, the TOA positioning algorithm is used in this embodiment for subsequent explanation.

[0049] See Figure 2As shown, this application provides a phase-shift code calculation method based on a field-programmable gate array (FPGA) chip. This method can be executed in parallel by multiple switching units contained in the FPGA chip, and the parallel execution is as follows: Figure 3 As shown, for a single switching unit, the phase-shift code calculation method includes:

[0050] S201: In response to the ultra-wideband positioning information input to the receiving antenna, calculate the trigonometric function data between the receiving antenna and the transmitting antenna.

[0051] Optionally, the trigonometric function data between the receiving antenna and the transmitting antenna can be obtained by looking up a table.

[0052] Specifically, in one optional embodiment, a preset lookup table is used to process the beam phase angle θ and elevation angle Φ between the receiving antenna and the transmitting antenna in the ultra-wideband positioning information to obtain multiple trigonometric function values ​​sinθ, cosθ, and sinΦ corresponding to the beam phase angle θ and the elevation angle Φ, wherein the beam phase angle θ and the elevation angle Φ are obtained based on the positioning position of the receiving antenna.

[0053] Furthermore, to save storage space in the algorithm, trigonometric function induction formulas, such as sine-cosine conversion formulas, are used to process the multiple trigonometric function values ​​sinθ, cosθ, and sinΦ respectively, so as to induce them into their respective sine values ​​on a quarter-cycle for storage.

[0054] For example, when the beam phase angle θ is in (0°, 90°), its trigonometric function value sinθ is retained as the corresponding sine value sinθ, and its trigonometric function value cosθ is retained as the corresponding sine value sin(90°-θ); when the beam phase angle θ is in (90°, 180°), its trigonometric function value sinθ is retained as the corresponding sine value sin(180°-θ), and its trigonometric function value cosθ is retained as the corresponding sine value. The result is sin(θ-90°).

[0055] Based on the above method, the trigonometric function data sinθ, cosθ, and sinΦ between the receiving antenna and the transmitting antenna are obtained.

[0056] S202: Performs multi-time operation between trigonometric function data and preset parameters to obtain intermediate variables, and inputs the intermediate variables and the power of the ordinate corresponding to the receiving antenna into the multiplier of the field programmable gate array chip to obtain the data result output by the multiplier.

[0057] Furthermore, the step of performing multi-time-series operations on the trigonometric function data and preset parameters to obtain intermediate variables specifically includes:

[0058] S2021: In the first time sequence, calculate the first sub-variable P1 = cosθsinΦ and the second sub-variable P2 = d1 / λsinθ, where d1 is the preset longitudinal antenna spacing and λ is the wavelength.

[0059] S2022: In the second time sequence, calculate the third sub-variable P3 = d2 / λ*P2, where d2 is the preset lateral antenna spacing.

[0060] Optionally, the calculation processes of P1 and P2 can be performed simultaneously in the field programmable gate array (FPGA) chip. The above-mentioned d1 / λ and d2 / λ can be calculated in real time during the steps, or they can be obtained in advance based on the fixed parameters of the radar array.

[0061] S2023: In the third time sequence, calculate the fourth sub-variable P4 = K * P3 and the fifth sub-variable P5 = i * P3, and calculate the intermediate values ​​corresponding to the fourth sub-variable P4 and the fifth sub-variable P5 to obtain intermediate variables, where i and K are the horizontal and vertical coordinates of the position of the corresponding array element of the receiving antenna.

[0062] Based on the above method, the required intermediate variable middata is quickly obtained. Then, in S202, the intermediate variable middata needs to be raised to the power of 2 with the vertical coordinate corresponding to the receiving antenna. K Input the multiplier (i.e., the multiplication IP core) of the field-programmable gate array chip to obtain the corresponding data result output by the multiplier, where 2 K It can also be obtained through phase shifting.

[0063] S203: The data results are processed using multiple segments and a limited phase shift accuracy to obtain the phase shift code of the receiving antenna.

[0064] Furthermore, the data results are normalized using multiple intervals to obtain the required phase shift angle of the receiving antenna. In this embodiment, to improve the processing speed of the algorithm, multiple intervals that the data may fall into are set, wherein each interval contains a range of not less than 360°.

[0065] Preferably, the multiple intervals set in the embodiments of this application may include different intervals such as (-720°, -360°), (-360°, 0), and (360°, 720°). Each interval ranges 360°. The range of the data result is determined to fall into the interval, and the interval value (a multiple of 360°) of the interval is added or subtracted based on the interval. For example, if it falls into (-360°, 0), the corresponding interval value of 360° is added until the data falls into (0, 360°), at which point the data is considered to be normalized.

[0066] Furthermore, the data results are processed using multiple planning intervals corresponding to the limited phase shift accuracy settings, so as to determine the phase shift code of the receiving antenna based on the planning interval to which the data results finally belong.

[0067] For example, see Figure 4 As shown, the calculated data result is divided by the phase shift accuracy, and the result is the phase shift code of the phase shifter. Taking a phase shifter with a phase shift accuracy of 5.625° as an example, the corresponding planning interval is set as: (0, 2.8125°), (2.8125°, 8.4375°)... Based on the final interval result, the phase shift code of the receiving antenna is obtained.

[0068] In one optional embodiment, the ultra-wideband positioning information input to the receiving antenna is obtained by trial and error adjustment based on the known transmitting antenna angle. Specifically, the transmitting antenna is made to scan near a specified transmitting angle, and the transmitting angle is adjusted according to the feedback power of the receiving antenna, thereby eliminating a certain degree of environmental error.

[0069] See Figure 5 The diagram shown is a flowchart of the phase-shift code calculation method based on a field-programmable gate array chip provided in this application embodiment. The phase-shift code calculation process is parallelized through trigonometric function calculation, multiplication IP processing, and normalization processing, which reduces data storage occupation, thereby reducing the power consumption of the algorithm and improving the overall calculation efficiency.

[0071] The switching matrix module 601 includes multiple switching units, each of which is connected to an input channel 602 and corresponds to an output port 603. Each input channel 602 is used to transmit ultra-wideband positioning information to the switching unit. The multiple switching units execute the steps of the following method in parallel. For one switching unit, the steps of the method include:

[0072] In response to the ultra-wideband positioning information input to the receiving antenna, trigonometric function data between the receiving antenna and the transmitting antenna is calculated, wherein the trigonometric function data is obtained based on a preset lookup table;

[0073] Multiple time-series operations are performed between the trigonometric function data and preset parameters to obtain intermediate variables.
