Embodiment 1
[0075] Embodiment 1, an embodiment of the antenna calibration method in this application, includes:
[0076] 301. The calibration device acquires a first relative value between two loop calibration signals corresponding to a transceiver unit group.
[0077] In this embodiment, the calibration device obtains the loop calibration signal corresponding to the first transceiver unit in the transceiver unit group, and simultaneously obtains the loop calibration signal corresponding to the second transceiver unit. Secondly, the calibration device obtains the loop calibration signal corresponding to the two loop calibration signals. The first relative value between.
[0078] As shown in Figure 2, the transceiver unit group can be a combination of any two transceivers from transceiver 0 to transceiver N, the transceiver unit in the transceiver unit group is equivalent to a transceiver, the first transceiver unit in the following embodiment The transceiver 0 is taken as an example for ...
Embodiment 2
[0107] Embodiment 2, an embodiment of the calibration value verification method in this application, including:
[0108] 401. The calibration device acquires an amplitude parameter synthesized by two radio frequency signals generated by the transceiver unit group.
[0109] In this embodiment, the calibration device collects amplitude parameters synthesized by two radio frequency signals generated by the transceiver unit group.
[0110] Optionally, the calibration device collects four amplitude parameters synthesized by the two radio frequency signals respectively generated by the transceiver 1 and the transceiver 2 through the wireless probe. The specific implementation is as follows:
[0111] like Figure 5 As shown, point O is the position corresponding to transceiver 0, point A is the position of transceiver 1, and a wireless probe for collecting signals is placed at position D, and O, A, and D are located in the XOY plane at the same time, where DB=DA , r=R1-R0, besides...
Embodiment 3
[0152] Embodiment three, such as Image 6 As shown, a schematic diagram of an embodiment of the calibration device in this application includes: a high-precision scanning frame, a laser ranging sensor, a wireless probe, an active antenna, a feeding platform, a communication exchange unit, a communication control unit, a power supply unit, and an axis control unit. device, external sampling operation unit, main console and two couplers, the connection relationship between each object is as follows Image 6 As shown, it should be noted that, Image 6 Shown above is a small darkening chamber.
[0153] The wireless probe and the laser ranging sensor are fixed together and suspended on the high-precision scanning frame. The axis controller can control the high-precision scanning frame to move up and down, left and right, and forward and backward in space; the wireless probe is used to collect data emitted by the active antenna. The radio frequency signal, and the distance D from ...
