Description

Technical Field

[0001] The invention relates to the field of satellite communications, in particular to a transceiver polarization tracker and a polarization tracking method of the transceiver polarization tracker. Background Art

[0002] The polarization of an electromagnetic wave is defined as the oscillation direction of the electric field vector. If the projection of the electric field vector on a plane perpendicular to the propagation direction is a straight line, it is called a linearly polarized wave. Some satellite communication systems use orthogonal linear polarization signals for communication.

[0003] In satellite communications, the electromagnetic waves radiated or received by the antennas have specific polarization directions. When the polarization directions of the receiving antenna and the transmitting antenna are inconsistent, the quality of the received signal will be reduced.

[0004] Due to the difference in longitude and latitude between the antenna's geographical location and the satellite's downlink point and the curvature of the earth, the polarization of the satellite transponder's radiation wave has a certain angle relative to the polarization of the satellite communication equipment antenna. This angle is called the satellite's polarization deflection angle. When the antenna is pointed at the satellite, the polarization of the antenna should be adjusted to match the satellite's polarization orientation in different regions.

[0005] Therefore, for this type of satellite communication system, it is necessary to design a transceiver polarization tracker for the local satellite communication equipment to facilitate adjusting the polarization direction of the antenna transceiver line to be consistent with the changing satellite polarization direction. Summary of the invention

[0006] The object of the present invention is to provide a transceiver polarization tracker to adjust the transceiver linear polarization direction of the satellite communication equipment antenna in order to solve all or part of the above problems.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A transceiver polarization tracker includes a first polarization rotation mechanism, a first in-phase orthogonal mode coupler, a duplexer, a phase adjustment module, a second in-phase orthogonal mode coupler, and a second polarization rotation mechanism;

[0009] The transmission signal is transmitted into the first in-phase orthogonal mode coupler with the first linear polarization through the first polarization rotation mechanism, and a group of in-phase radio frequency signals are separated and enter the duplexer, and are phase-modulated and outputted through the phase adjustment module;

[0010] A group of received signals are adjusted to the same phase by the phase adjustment module and enter the duplexer, and then transmitted to the second in-phase orthogonal mode coupler to be synthesized into a second linear polarization signal, and the second polarization rotation mechanism is aligned with the second polarization signal for reception.

[0011] Furthermore, the polarization direction of the first polarization rotation mechanism and / or the second polarization rotation mechanism is adjusted by rotating the configuration feeding needle in the first polarization rotation mechanism and / or the second polarization rotation mechanism.

[0012] Furthermore, the first polarization rotation mechanism and / or the second polarization rotation mechanism uses a coupled feeding waveguide with a stepped gradient structure to perform impedance matching on the transmission signal and / or the reception signal.

[0013] Furthermore, the configuration feeding needle is arranged in the polarization rotation cavity of the polarization rotation mechanism and is driven by the rotating axis; the coupling feeding waveguide is connected to the polarization rotation cavity via air coaxiality, and the configuration feeding needle passes through the air coaxiality to be connected to the rotating axis.

[0014] Furthermore, the first in-phase orthogonal mode coupler and / or the second in-phase orthogonal mode coupler comprises a coupling main port, the coupling main port is connected to a polarization separator, and the polarization separator is connected to two in-phase ports via two phase adjustment waveguides.

[0015] Furthermore, one of the two phase adjustment waveguides is connected to the polarization separator via a cross-shaped polarization rotation waveguide and a 90-degree bending waveguide.

[0016] Furthermore, the phase adjustment waveguide adopts a combined structure of a serpentine waveguide and a wide-narrow waveguide.

[0017] Furthermore, the duplexer is a back-to-back symmetrical structure, and includes two total transceiver ports, a dual-channel 13.75-14.5GHz port and a dual-channel 10.7-12.75GHz port, and the two total transceiver ports are connected to one channel of the two ports respectively.

[0018] Furthermore, the phase adjustment module is a symmetrical stepped structure waveguide.

[0019] The present invention also provides a polarization tracking method of a transceiver polarization tracker, which comprises:

[0020] The polarization direction of the second polarization rotation mechanism is adjusted to the maximum value of the beacon signal feedback level.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] The transceiver polarization tracker of the present invention utilizes the cooperation of a duplexer, an in-phase orthogonal mode coupler and a polarization rotation mechanism to realize the transceiver reciprocity of satellite communication equipment in the same polarization tracker, that is, on the basis of the same transceiver total port, the adjustment of the transmit and receive polarization directions is realized, thereby realizing the alignment of the transmit and receive polarizations.

DETAILED DESCRIPTION

[0044] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0045] Any feature disclosed in this specification (including any additional claims and abstract), unless otherwise stated, may be replaced by other equivalent or alternative features having similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0046] A transmit and receive polarization tracker, such as Figure 1 , Figure 2 As shown, the transceiver polarization tracker includes a first polarization rotation mechanism 1, a first in-phase orthogonal mode coupler 2, a duplexer 3, a phase adjustment module, a second in-phase orthogonal mode coupler 6 and a second polarization rotation mechanism 7.

[0047] The first polarization rotation mechanism 1 and the second polarization rotation mechanism 7 are responsible for adjusting the polarization directions of the transmission signal and the reception signal respectively.

[0048] Specifically, for the transmission signal, the transmission signal (generated by the satellite communication equipment) is transmitted with the first linear polarization through the first polarization rotation mechanism 1 and enters the first in-phase orthogonal mode coupler 2, and a group of in-phase RF signals are separated and enter the duplexer 3, and are phase-adjusted and output (to the antenna) by the phase adjustment module.

[0049] For the received signal, a group of received signals (received by the antenna) are adjusted to the same phase by the phase adjustment module and then enter the duplexer 3, and then transmitted to the second in-phase orthogonal mode coupler 6 to be synthesized into a second linear polarization signal, and the second polarization rotation mechanism 7 is aligned with the second polarization signal for reception.

[0050] like Figure 3 As shown, in some embodiments, a first configuration feeding needle 11 and a first rotating axis 12 are provided in the first polarization rotation mechanism 1, and the first configuration feeding needle 11 is connected to the end of the first rotating axis 12, and the first configuration feeding needle 11 is driven by the first rotating axis 12 to rotate to adjust the polarization direction of the first polarization rotation mechanism 1 (to the first polarization).

[0051] like Figure 3 As shown, in some embodiments, the first polarization rotation mechanism 1 is provided with a polarization rotation cavity 13, and the first configuration feeding needle 11 is located in the polarization rotation cavity 13, as shown in FIG. Figure 5 As shown, it is driven by the first rotating shaft 12 extending into the polarization rotation cavity 13, as shown in FIG. Figure 6 As shown, the first configuration feeding needle 11 can rotate 360 ​​degrees. In addition, the first polarization rotation mechanism 1 is also provided with a signal input port 15, and the transmission signal enters the polarization rotation cavity 13 through the signal input port 15, and then enters the polarization rotation cavity 13 through the air coaxial 14. The first configuration feeding needle 11 passes through the air coaxial 14 and is connected to the first rotation axis 12.

[0052] Furthermore, a coupling feeding waveguide 16 is provided at the signal input port 15 to perform impedance matching on the transmission signal. Figure 4 As shown, in some embodiments, the coupling feeding waveguide 16 adopts a stepped gradient structure.

[0053] As for the second polarization rotation mechanism 7, see the attached Figure 2 In some embodiments, a second configuration feeding needle and a second rotating axis are provided in the second polarization rotation mechanism 7. The second configuration feeding needle is connected to the end of the second rotating axis. The second configuration feeding needle is driven to rotate by the second rotating axis to adjust the polarization direction to align with the second polarization signal from the antenna.

[0054] In some embodiments, see Appendix Figure 2 The second polarization rotation mechanism 7 is provided with a polarization rotation cavity 13, and the second configuration feeding needle is located in the polarization rotation cavity 13 and is driven by the second rotation axis extending into the polarization rotation cavity 13. In addition, the second polarization rotation mechanism 7 is also provided with a signal output port, and the received signal is output from the polarization rotation cavity 13 to the communication device through the air coaxial 14 from the signal output port. The second configuration feeding needle passes through the air coaxial 14 and is connected to the second rotation axis.

[0055] Furthermore, a coupling feed waveguide 16 is provided at the signal output port to perform impedance matching on the received signal. Figure 4 As shown, the coupling feeding waveguide 16 adopts a stepped gradient structure.

[0056] The first polarization rotation mechanism of the above embodiment is simulated, and the simulation results are as follows: Figure 7-10 As shown, Figure 7 This is the 13.75-14.5GHz standing wave simulation result diagram. Figure 8 This is the insertion loss simulation result diagram of 13.75-14.5GHz. Fig. 9 This is the 10.7-12.8GHz standing wave simulation result diagram. Fig.10 This is a simulation result diagram of insertion loss at 10.7-12.8 GHz. It can be seen from the simulation results that the impedance matching of the first polarization rotation mechanism 1 is ≤1.25, and the loss is very low. During the rotation of the first rotation axis 12, the standing wave loss is very stable.

[0057] like Fig.11 As shown, in some embodiments, the first in-phase orthogonal mode coupler 2 includes a coupling main port 21, the coupling main port 21 is connected to a polarization separator 22, and the polarization separator 22 is connected to two in-phase ports via two phase adjustment waveguides.

[0058] For the transmitting signal, after the transmitting signal transmitted from the first polarization rotation mechanism enters the first in-phase orthogonal mode coupler 2 from the coupling main port 21, it is separated into a group of orthogonal signals by the polarization separator 22 in the first in-phase orthogonal mode coupler 2. The group of orthogonal signals are transmitted in the same direction through the first phase adjustment waveguide 24 and the second phase adjustment waveguide 25 respectively, and the phases of the signals output from the two phase adjustment waveguides are made the same, and finally output from the first in-phase port 26 and the second in-phase port 27 respectively.

[0059] In some embodiments, the second phase adjustment waveguide 25 in the first in-phase orthogonal mode coupler 2 is connected to the polarization separator 22 via the cross-shaped polarization rotation waveguide and the 90-degree bend waveguide 23. That is, among a group of orthogonal signals separated by the polarization separator 22, one signal passes through the cross-shaped polarization rotation waveguide and the 90-degree bend waveguide 23, enters the second phase adjustment waveguide 25, and is then connected to the second in-phase port 27. The other signal is connected from the polarization separator 22 to the first in-phase port 26 via the first phase adjustment waveguide 24.

[0060] In some embodiments, the second in-phase orthogonal mode coupler 6 includes a coupling main port 21, which is connected to a polarization separator 22, and the polarization separator 22 is connected to two in-phase ports via two phase adjustment waveguides, that is, the structure is the same as the first in-phase orthogonal mode coupler 2 in the aforementioned embodiments.

[0061] For the receiving signal, a group of receiving signals transmitted from the duplexer 3 are input from two in-phase ports respectively, and then transmitted in-phase through two phase-adjusted waveguides respectively to obtain a group of orthogonal signals. The two phase-adjusted waveguides transmit the group of orthogonal signals to the polarization separator 22 for combined output, and output to the second polarization rotation mechanism 7.

[0062] In some embodiments, one of the two phase adjustment waveguides in the second in-phase orthogonal mode coupler 6 is connected to the polarization separator 22 via the cross-shaped polarization rotation waveguide and the 90-degree bend waveguide 23. That is, of the two orthogonal signals transmitted through the phase adjustment waveguide, one signal is transmitted to the polarization separator 22 after passing through the cross-shaped polarization rotation waveguide and the 90-degree bend waveguide 23. The other signal is connected to the polarization separator 22 from the corresponding in-phase port via another phase adjustment waveguide. In some specific embodiments, the structure of the second in-phase orthogonal mode coupler 6 can directly refer to the first in-phase orthogonal mode coupler 2.

[0063] The principle of phase adjustment waveguide:

[0064] After two groups of electromagnetic waves pass through different devices, the phase difference slope within the bandwidth is unknown. The phase adjustment waveguide adopts a combination design of serpentine waveguide and wide and narrow waveguide. The serpentine waveguide is a waveguide with the same caliber, and its length difference can affect the phase superposition of electromagnetic waves within the cycle. The electromagnetic waves pass through waveguides of the same length but different calibers, and the paths they take are also different, so the phase difference slope required for the two groups of signals separated by the orthogonal mode coupler can be adjusted.

[0065] The first (or second) in-phase orthogonal mode coupler 2 of the above embodiment structure is simulated, and the phase and loss simulation data obtained are as follows: Figure 12-14 As shown, Fig.12 This is the 13.75-14.5GHz loss simulation result diagram. Fig.13 This is the 13.75-14.5GHz phase simulation result diagram. Fig.14 This is the 10.7-12.8GHz loss simulation result diagram. Fig.15 This is the 10.7-12.8GHz phase simulation result diagram. Fig.12 , Fig.13 It can be seen that the phase change is within 1 degree at 13.75-14.5GHz, and the loss is ≤0.1dB, which is almost negligible. Fig.14 , Fig.15 It can be seen that at 10.7-12.8 GHz, the phase variation is within the range of 1.8° and the loss is ≤0.1 dB, which can also be ignored. The indicators are fully sufficient to meet the task requirements of in-phase processing.

[0066] In some embodiments, the duplexer 3 adopts a back-to-back symmetrical structure. Fig.16 As shown, in some embodiments, the duplexer 3 includes two total transceiver ports, namely Fig.16The figure shows a first transceiver main port 31 facing upward and a second transceiver main port 32 facing downward; it also includes a (right side) dual-channel 13.75-14.5GHz port 33 and a (left side) dual-channel 10.7-12.75GHz port 34; the two transceiver main ports are connected to a channel of the two ports respectively, that is, the first transceiver main port 31 is connected to the upper channels of the 13.75-14.5GHz port 33 and the 10.7-12.75GHz port 34 respectively, and the second transceiver main port 32 is connected to the lower channels of the 13.75-14.5GHz port 33 and the 10.7-12.75GHz port 34 respectively. Between the two transceiver ports and the left 13.75-14.5GHz port 33, a first isolation structure 35 is provided to conduct the 13.75-14.5GHz frequency band and suppress the 10.7-12.75GHz frequency band. Between the transceiver port and the right 10.7-12.75GHz port 34, a second isolation structure 36 is provided to conduct the 10.7-12.75GHz frequency band and suppress the 13.75-14.5GHz frequency band. The first isolation structure 35 and the second isolation structure 36 are both symmetrical structures (based on Fig.16 angle shown).

[0067] The loss and filtering effect of the duplexer 3 of the above embodiment structure are simulated, and the results are as follows: Fig.17 As shown. Fig.17 It can be seen that the loss from the total transceiver port to the 13.75-14.5GHz port 33 on the left is -0.05dB, and the suppression of the 10.7-12.75GHz frequency band reaches -80.5dB; the loss from the total transceiver port to the 10.7-12.75GHz port 34 on the right is -0.0045dB, and the suppression of the 13.75-14.5GHz frequency band reaches -102.6dB, and the duplex index is very good.

[0068] Figure 1 As shown, in some embodiments, phase adjustment modules are respectively connected to the two transceiver ports of the duplexer 3 , including a first phase adjustment module 4 connected to the first transceiver port 31 , and a second phase adjustment module 5 connected to the second transceiver port 32 .

[0069] In some embodiments, Fig.18As shown, one of the two phase adjustment modules adopts a symmetrical step structure waveguide design. Specifically, the phase adjustment module includes a tubular phase adjustment module body 41, and a symmetrical step waveguide 42 arranged on the inner wall of the phase adjustment module body 41. The so-called symmetrical step waveguide 42 includes two meanings, one of which is a left-right symmetrical step structure, that is, it is centrally symmetrical about the axis of the phase adjustment module (that is, the signal transmission direction), and the other is a top-bottom symmetrical step structure, that is, it is symmetrical about the mid-vertical plane of the axis of the phase adjustment module.

[0070] In fact, one of the two phase adjustment modules can be designed as the symmetrical stepped structure, for example Figure 2 In the embodiment, the second phase adjustment module 5 connected to the second transceiver main port 32 facing downward adopts the symmetrical stepped structure waveguide design, while the first phase adjustment module 4 connected to the first transceiver main port 31 facing upward adopts an air waveguide with a pipe structure, that is, only the phase adjustment module main body 41 part does not include the symmetrical stepped waveguide 42.

[0071] The working principle of the phase adjustment module of the symmetrical step waveguide 42 structure is as follows: the function of the phase adjustment module is to make the electromagnetic wave pass through the symmetrical step waveguide component, and the phase changes by the same phase angle within the bandwidth. In some embodiments, the phase adjustment module uses a set of steps that change the phase by 105°.

[0072] like Fig.19 The following is a simulation result of the performance simulation of the phase adjustment module of this embodiment. Fig.19 From the simulation results, we can see that a group of signals passing through the same length of air and step waveguide have a phase difference of 99-110 degrees in the full frequency range of 10.7-14.5GHz, and the error is within 6 degrees. The system output with a phase difference in a stable value range across the entire frequency band can be debugged.

[0073] In summary, according to the embodiments of the present application, the advantages of the designed retractable polarization tracker are:

[0074] Connecting polarization tracking and polarization transmission through a back-to-back duplexer 3 realizes an integrated design of transmitting and receiving polarization tracking, and the structure is more compact. Each component has been optimized to make the polarization tracking impedance matching bandwidth wider, reaching a bandwidth coverage of 10.7-12.75GHz for reception and 13.75-14.5GHz for transmission, far exceeding the existing tracker bandwidth of 12.25-12.75GHz / 14-14.5GHz.

[0075] In addition, the transceiver polarization tracker solves the problem of easy detachment caused by the unstable connection method of bonding the medium and the rotating axis of the existing polarization tracker. By adopting the rotating axis coupling feeding output (or input) port, the rotating axis can be directly connected to the motor without the need for a medium transition.

[0076] In addition, the transceiver polarizer also solves the problem that the two output ports of the orthogonal mode coupler in the existing polarization tracker are not parallel and have different phases. The cross-coupling slot is used to adjust the polarization of the output ports to be the same. The problem of different phases of the output ports can be solved by using a phase adjustment waveguide.

[0077] The transceiver polarizer solves the problem of inconsistent orthogonal phase of the system output after the existing polarization tracker is connected to the antenna. By adding a phase adjustment module to the transceiver and tracker's transceiver port, the inconsistent phase of the system output can be partially adjusted.

[0078] When the antenna of the ground satellite communication equipment is working, the transceiver polarization tracker needs to perform polarization tracking. The satellite polarization deflection angle can be calculated by combining the ground position information given by the positioning module and the satellite position information through methods known in the art. The polarization tracking unit of the antenna control system transmits the satellite polarization deflection angle to the second polarization rotation mechanism 7 in real time, adjusts the polarization direction of the second polarization rotation mechanism 7, and the second polarization rotation mechanism 7 drives the polarization of the in-phase orthogonal mode coupler to rotate the angle so that its polarization is consistent with the polarization of the satellite downlink signal. When the beacon signal feedback level is at the maximum value, it is determined that the current ground satellite equipment antenna is aligned with the tracking satellite.

[0079] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
