Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of antenna technology and related technical fields, specifically to a method, apparatus, device, and medium suitable for controlling the scanning angle of a phased array antenna. Background Technology

[0002] With the development of wireless communication technology, the demand for antennas with a wide scanning angle range, high gain, small size, and light weight is gradually increasing.

[0003] In the existing technology, the scanning angle range of phased array antennas is generally 60° off-axis. If the scanning angle is increased, grating lobes will appear in the direction opposite to the main beam in the radiation pattern under the antenna scanning. At the same time, the gain of the main beam will drop significantly, resulting in a reduction in the overall performance of the antenna. Summary of the Invention

[0055] In view of the problems existing in the prior art, this disclosure provides a method for controlling the scanning angle of a phased array antenna. Figure 1 This is a flowchart illustrating a phased array antenna scanning angle control method provided in an embodiment of this disclosure, as shown below. Figure 1 As shown, the phased array antenna scanning angle control method includes:

[0056] S110. Obtain the angle information of the target object relative to the target antenna.

[0057] In a specific implementation, the angle information of the target object relative to the target antenna can be determined based on the position information of the target object and the position information of the target antenna.

[0058] It should be noted that in this embodiment of the disclosure, the target antenna can be applied to radar, satellite communication, or point-to-point communication.

[0059] S120. Based on the angle information of the target object relative to the target antenna, determine the conduction mode of the switch module connected to the feed interface of the target antenna.

[0060] Existing phased array antennas typically have a scanning angle range of 60° off-axis. Increasing the scanning angle results in grating lobes appearing in the direction opposite to the main beam in the antenna's scanned radiation pattern, while the main beam gain decreases significantly, leading to a reduction in overall antenna performance. To extend the scanning angle of phased array antennas, enabling them to operate at larger scanning angles without performance degradation, a method for extending the scanning angle of phased array antennas with reconfigurable radiation patterns is proposed. This method reconstructs the radiation patterns of antenna elements by switching between different modes, achieving large-angle scanning using the radiation patterns of different antenna elements. Furthermore, this method increases the distance between antenna elements, thereby reducing the heat density of the phased array antenna and improving its heat dissipation capabilities.

[0061] Based on the problems existing in the prior art, the phased array antenna scanning angle control method provided in this disclosure first determines the conduction mode of the switch module connected to the feed interface of the target antenna according to the angle information of the target object relative to the target antenna. Then, according to the determined conduction mode of the switch module connected to the feed interface of the target antenna, a control command is output to the switch module so that the feed interface receives the feed signal. Finally, according to the feed signal received by the feed interface, the target operating mode of the target antenna is determined, and the target antenna is switched to the target operating mode so that the target scanning angle of the target antenna in the target operating mode covers the target object. There is a correspondence between the conduction mode of the switch module, the operating mode of the target antenna, and the scanning angle of the target antenna.

[0062] Specifically, in combination Figure 2 The target antenna features a reconfigurable radiation pattern across three modes. In each mode, the 3dB beamwidth is no less than 60°. Specifically, the beam scanning angle range for the target antenna is -90° to -30° in mode 1, -30° to 30° in mode 2, and 30° to 90° in mode 3. Because the target antenna has three reconfigurable radiation patterns, its beam scanning angle coverage ranges from -90° to 90°, achieving a large-angle scan.

[0063] As a specific implementation method, based on the angle information of the target object relative to the target antenna, the conduction mode of the switch module connected to the feed interface of the target antenna is determined, including: when the angle information of the target object relative to the target antenna is within a first angle range, the conduction mode of the switch module connected to the feed interface of the target antenna is determined to be a first conduction mode, wherein the first angle range is -90° to -30°; when the angle information of the target object relative to the target antenna is within a second angle range, the conduction mode of the switch module connected to the feed interface of the target antenna is determined to be a second conduction mode, wherein the second angle range is -30° to 30°; when the angle information of the target object relative to the target antenna is within a third angle range, the conduction mode of the switch module connected to the feed interface of the target antenna is determined to be a third conduction mode, wherein the third angle range is 30° to 90°.

[0064] Specifically, when the switching module is in the first conduction mode, the target antenna operates in the first operating mode, and the scanning angle range of the target antenna is -90° to -30°. When the switching module is in the second conduction mode, the target antenna operates in the second operating mode, and the scanning angle range of the target antenna is -30° to 30°. When the switching module is in the third conduction mode, the target antenna operates in the third operating mode, and the scanning angle range of the target antenna is 30° to 90°.

[0065] As a specific implementation method, such as Figure 3 As shown, the switching module includes a first switching unit and a second switching unit. The feed interface of the target antenna includes a first feed interface and a second feed interface. The first feed interface is electrically connected to the first end of the first switching unit. The second end of the first switching unit receives a feed signal of the first phase, and the third end of the first switching unit receives a feed signal of the second phase. The second feed interface is electrically connected to the first end of the second switching unit. The second end of the second switching unit receives the feed signal of the first phase, and the third end of the second switching unit receives the feed signal of the second phase. The phase difference between the first phase and the second phase is 90 degrees.

[0066] Based on the angle information of the target object relative to the target antenna, the conduction mode of the switch module connected to the feed interface of the target antenna is determined, including: when the angle information of the target object relative to the target antenna is within a first angle range, the first switch unit electrically connected to the first feed interface is determined to be in a first type of conduction mode, and the second switch unit electrically connected to the second feed interface is determined to be in a second type of conduction mode; when the angle information of the target object relative to the target antenna is within a second angle range, the first switch unit electrically connected to the first feed interface is determined to be in a second type of conduction mode, and the second switch unit electrically connected to the second feed interface is determined to be in a first type of conduction mode; when the angle information of the target object relative to the target antenna is within a third angle range, the first switch unit electrically connected to the first feed interface is determined to be in a second type of conduction mode, and the second switch unit electrically connected to the second feed interface is determined to be in a second type of conduction mode.

[0067] Specifically, the first switching unit includes a first single-pole double-throw (SPD) switch, and the second switching unit includes a second SPD switch. The first terminal of the first SPD switch is electrically connected to the first feed interface, and the second terminal of the first SPD switch receives a first-phase feed signal. The third terminal of the first SPD switch receives a second-phase feed signal. The first terminal of the second SPD switch is electrically connected to the second feed interface, and the second terminal of the second SPD switch receives the first-phase feed signal. The third terminal of the second SPD switch receives the second-phase feed signal. The first-phase feed signal is 0°, and the second-phase feed signal is 90°. When the angle information of the target object relative to the target antenna is within a first angle range, the first switching unit operates in a first-type conduction mode, and the second switching unit operates in a second-type conduction mode. That is, the moving contact of the first SPD switch is electrically connected to the first stationary contact, the first feed interface receives the first-phase feed signal, and the moving contact of the second SPD switch is electrically connected to the second stationary contact, the second feed interface receives the second-phase feed signal. When the angle information of the target object relative to the target antenna is within the second angle range, the first switching unit operates in the second type of conduction mode, and the second switching unit operates in the first type of conduction mode. That is, the moving contact of the first single-pole double-throw switch is electrically connected to the second stationary contact, the first feed interface receives the second-phase feed signal, the moving contact of the second single-pole double-throw switch is electrically connected to the first stationary contact, and the second feed interface receives the first-phase feed signal. When the angle information of the target object relative to the target antenna is within the third angle range, the first switching unit operates in the second type of conduction mode, and the second switching unit operates in the second type of conduction mode. That is, the moving contact of the first single-pole double-throw switch is electrically connected to the second stationary contact, the first feed interface receives the second-phase feed signal, the moving contact of the second single-pole double-throw switch is electrically connected to the second stationary contact, and the second feed interface receives the second-phase feed signal.

[0068] As another specific implementation method, such as Figure 4As shown, the switch module includes a third switch unit, a fourth switch unit, and a fifth switch unit. The feed interface of the target antenna includes a third feed interface, a fourth feed interface, and a fifth feed interface. The first end of the third switch unit is electrically connected to the third feed interface, the first end of the fourth switch unit is electrically connected to the fourth feed interface, and the first end of the fifth switch unit is electrically connected to the fifth feed interface. The second ends of the third switch unit, the fourth switch unit, and the fifth switch unit respectively receive the feed signal.

[0069] Based on the angle information of the target object relative to the target antenna, the conduction mode of the switch module connected to the feed interface of the target antenna is determined, including: when the angle information of the target object relative to the target antenna is within a first angle range, the third switch unit is determined to be in a conducting state, and the fourth and fifth switch units are in a de-conducting state; when the angle information of the target object relative to the target antenna is a second angle, the fourth switch unit is determined to be in a conducting state, and the third and fifth switch units are in a de-conducting state; when the angle information of the target object relative to the target antenna is a third angle, the fifth switch unit is determined to be in a conducting state, and the third and fourth switch units are in a de-conducting state.

[0070] When the angle information of the target object relative to the target antenna is within the first angle range, the third switch unit is in the on state, and the fourth and fifth switch units are in the off state. That is, the third feed interface receives a feed signal, while the fourth and fifth feed interfaces do not receive a feed signal. When the angle information of the target object relative to the target antenna is within the second angle range, the fourth switch unit is in the on state, and the third and fifth switch units are in the off state. That is, the fourth feed interface receives a feed signal, while the third and fifth feed interfaces do not receive a feed signal. When the angle information of the target object relative to the target antenna is within the third angle range, the fifth switch unit is in the on state, and the third and fourth switch units are in the off state. That is, the fifth feed interface receives a feed signal, while the third and fourth feed interfaces do not receive a feed signal.

[0071] S130. Based on the determined conduction mode of the switch module connected to the feed interface of the target antenna, output control commands to the switch module so that the feed interface receives the feed signal.

[0072] After determining the conduction mode of the switch module connected to the feed interface of the target antenna in step S120, a control command is output to the switch module so that the switch module conducts according to the determined conduction mode, thereby enabling the feed interface of the target antenna to receive the feed signal.

[0073] Combination Figure 3When the target antenna's feed interface includes a first feed interface and a second feed interface, for example, the first phase feed signal received by the second terminals of the first and second switching units is a 0° feed signal, and the second phase feed signal received by the third terminals of the first and second switching units is a 90° feed signal. If the first switching unit is in a first type of conduction mode and the second switching unit is in a second type of conduction mode, then the first feed interface of the target antenna receives a 0° feed signal, and the second feed interface of the target antenna receives a 90° feed signal. If the first switching unit is in a second type of conduction mode and the second switching unit is in a first type of conduction mode, then the first feed interface of the target antenna receives a 90° feed signal, and the second feed interface of the target antenna receives a 0° feed signal. If the first switching unit is in a second type of conduction mode and the second switching unit is in a second type of conduction mode, then the first feed interface of the target antenna receives a 90° feed signal, and the second feed interface of the target antenna receives a 90° feed signal.

[0074] Combination Figure 4 When the target antenna's feed interface includes a third feed interface, a fourth feed interface, and a fifth feed interface, in one exemplary case, the second terminals of the first and second switching units receive a 0° feed signal for the first phase, while the second terminals of the third, fourth, and fifth switching units receive a 90° feed signal. If the third switching unit is in the ON state and the fourth and fifth switching units are in the OFF state, then the target antenna's third feed interface receives a 90° feed signal, and the target antenna's fourth feed interface receives a 90° feed signal. The electrical interface and the fifth feed interface did not receive a feed signal; if the fourth switch unit is in the on state and the third and fifth switch units are in the off state, the fourth feed interface of the target antenna receives a 90° feed signal, while the third and fifth feed interfaces of the target antenna do not receive a feed signal; if the fifth switch unit is in the on state and the third and fourth switch units are in the off state, the fifth feed interface of the target antenna receives a 90° feed signal, while the third and fourth feed interfaces of the target antenna do not receive a feed signal.

[0075] S140. Based on the power supply signal received from the power supply interface, determine the target operating mode of the target antenna and switch the target antenna to the target operating mode so that the target scanning angle of the target antenna in the target operating mode covers the target object.

[0076] After receiving the feed signal at the feed interface of the target antenna, the target operating mode of the target antenna can be determined, and the target antenna can be switched to the corresponding target operating mode.

[0077] An exemplary combination Figure 2 and Figure 3 If the first feed interface of the target antenna receives a feed signal of 0° and the second feed interface receives a feed signal of 90°, it indicates that the target object is within a first angular range (-90° to -30°). By controlling the target antenna to switch to a first operating mode, the scanning angle range of the beam generated by the target antenna in the first operating mode is -90° to -30°, and the scanning angle of the beam generated by the target antenna in the first operating mode covers the target object. If the first feed interface of the target antenna receives a feed signal of 90° and the second feed interface receives a feed signal of 0°, it indicates that the target object is within a second angular range (-30° to 30°). By controlling the target antenna to switch to the second working mode, the scanning angle range of the beam generated by the target antenna in the second working mode is -30° to 30°, and the scanning angle of the beam generated by the target antenna in the second working mode covers the target object; if the first feed interface of the target antenna receives a 90° feed signal and the second feed interface of the target antenna receives a 90° feed signal, it indicates that the target object is located within the third angle range (the third angle range is 30° to 90°). By controlling the target antenna to switch to the third working mode, the scanning angle range of the beam generated by the target antenna in the third working mode is 30° to 90°, and the scanning angle of the beam generated by the target antenna in the third working mode covers the target object.

[0078] Another exemplary combination Figure 2 and Figure 4If the first feed interface of the target antenna receives a feed signal of 0° and the second feed interface receives a feed signal of 90°, it indicates that the target object is within a first angular range (-90° to -30°). By controlling the target antenna to switch to a first operating mode, the scanning angle range of the beam generated by the target antenna in the first operating mode is -90° to -30°, and the scanning angle of the beam generated by the target antenna in the first operating mode covers the target object. If the first feed interface of the target antenna receives a feed signal of 90° and the second feed interface receives a feed signal of 0°, it indicates that the target object is within a second angular range (-30° to 30°). By controlling the target antenna to switch to the second working mode, the scanning angle range of the beam generated by the target antenna in the second working mode is -30° to 30°, and the scanning angle of the beam generated by the target antenna in the second working mode covers the target object; if the first feed interface of the target antenna receives a 90° feed signal and the second feed interface of the target antenna receives a 90° feed signal, it indicates that the target object is located within the third angle range (the third angle range is 30° to 90°). By controlling the target antenna to switch to the third working mode, the scanning angle range of the beam generated by the target antenna in the third working mode is 30° to 90°, and the scanning angle of the beam generated by the target antenna in the third working mode covers the target object.

[0079] In other words, in the phased array antenna scanning angle control method provided in this embodiment, if the target object is located within a first angle range in the initial state, the switching mode of the control switch module is used to switch the feed signal received by the feed interface of the target antenna. Then, according to the feed signal received by the feed interface, the working mode of the target antenna is switched so that the scanning angle of the beam generated by the target antenna in this working mode covers the target object. When the angle information of the target object relative to the target antenna changes as the target object moves, the switching mode of the control switch module is changed to change the feed signal received by the feed interface of the target antenna. Then, according to the feed signal received by the feed interface, the target antenna is switched to another working mode so that the scanning angle of the beam generated by the target antenna in this working mode covers the target object, thereby increasing the scanning angle of the target antenna. In addition, as the scanning angle of the target antenna increases, the spacing between two adjacent antennas increases, and the coupling between two adjacent antennas decreases.

[0080] The phased array antenna scanning angle control method provided in this embodiment first acquires the angle information of the target object relative to the target antenna; then, based on the angle information of the target object relative to the target antenna, it determines the conduction mode of the switch module connected to the feed interface of the target antenna; and based on the determined conduction mode of the switch module connected to the feed interface of the target antenna, it outputs a control command to the switch module so that the feed interface receives a feed signal; finally, based on the feed signal received by the feed interface, it determines the target operating mode of the target antenna and switches the target antenna to the target operating mode so that the target scanning angle of the target antenna in the target operating mode covers the target object. By changing the feed signal received by the feed interface through the switch module, the operating mode of the target antenna is changed. Since the scanning angle of the target antenna is different in different operating modes, the operating mode of the target antenna includes three operating modes. The three operating modes increase the scanning angle of the target antenna, thereby increasing the spacing between two adjacent antennas and reducing the coupling between two adjacent antennas.

[0081] Based on the above embodiments, Figure 5 This is a flowchart illustrating another phased array antenna scanning angle control method provided in this disclosure embodiment, as shown below. Figure 2 As shown, the phased array antenna scanning angle control method also includes:

[0083] The above embodiments exemplify an antenna scanning angle control method when a target object is included within the preset scanning angle range of the target antenna. When multiple target antennas are included within the preset scanning angle range of the target antenna, the specific implementation process of the antenna scanning angle control method is as follows: First, determine the target objects included within the preset scanning angle range of the target antenna.

[0084] It should be noted that the preset scanning angle range is -90° to 90°.

[0085] S101. When there are multiple target objects within the preset scanning angle range of the target antenna, the angle information of each target object relative to the target antenna is obtained sequentially.

[0086] Then, based on the position information of each target object and the position information of the target antenna, the angle information of each target object relative to the target antenna is determined.

[0088] S122. Determine the conduction mode of the switch module connected to the feed interface of the target antenna according to the clock control signal.

[0089] When the target antenna's preset scanning angle range includes multiple target objects, the clock control signal is determined by the angle information of each target object relative to the target antenna. Based on the clock control signal, the conduction mode of the switching module connected to the feed interface of the target antenna is determined within different clock control signals.

[0090] An exemplary combination Figure 2 and Figure 3 When the target antenna includes target object 1 within its first angular range and target object 3 within its third angular range, the determined clock control signals are: the first clock signal outputs a high level, the second clock signal outputs a low level, and the third clock signal outputs a high level. At this time, the switching module connected to the feed interface of the target antenna operates in the first type of conduction mode and the second type of conduction mode during the first clock signal. During the third clock signal, the first switching unit of the switching module connected to the feed interface of the target antenna operates in the second type of conduction mode and the second switching unit operates in the second type of conduction mode.

At this time, during the first clock signal, the third switch unit of the switch module connected to the feed interface of the target antenna is in the on state, and the fourth and fifth switch units are in the off state. During the second clock signal, the third, fourth, and fifth switch units of the switch module connected to the feed interface of the target antenna are all in the off state. During the third clock signal, the fifth switch unit of the switch module connected to the feed interface of the target antenna is in the on state, and the third and fourth switch units are in the off state.

[0092] The phased array antenna scanning angle control method provided in this embodiment determines a clock control signal based on the angle information of each target object relative to the target antenna when the target object is within a preset scanning angle range of the target antenna. Then, based on the clock control signal, the conduction mode of the switch module connected to the feed interface of the target antenna is determined to ensure that the target antenna covers the target object within the corresponding scanning angle range according to the clock control signal.

[0093] Based on the above embodiments, Figure 6 This is a schematic diagram of the structure of a phased array antenna scanning angle control device provided in an embodiment of this disclosure, as shown below. Figure 6 As shown, the phased array antenna scanning angle control device includes:
