Description

Distributed control method, system and device for liquid crystal phased array antenna radio frequency module TECHNICAL FIELD

[0001] The embodiment of the disclosure relates to, but is not limited to, the technical field of liquid crystal phased array, and particularly relates to a distributed control method, system and device for a liquid crystal phased array antenna radio frequency module. BACKGROUND

[0002] With the rapid rise of 5G millimeter wave communication and wideband low-orbit satellite communication, phased array antennas have begun an unprecedented development and have been widely applied in satellite communication and radar systems. Phased array antenna beam control is mainly achieved by receiving phased array antenna beam control instructions transmitted by an upper computer, calculating the phase difference and amplitude of a phase shifter module or a T / R (Transmitter and Receiver) chip through a beamforming algorithm module and a calibration unit, and controlling the phased array antenna beam.

[0003] Traditional phased array antennas generally adopt a centralized wave control scheme, which is characterized by unified operation of amplitude and phase values of each antenna unit in the array by a beam control module, and then transmitting the calculated amplitude and phase control codes to each unit. This scheme has less hardware equipment and is suitable for planar array antennas with a small number of array units and relatively simple operation. However, for distributed array antennas with a large number of array units and relatively complex operation, the operation time is often long, which seriously affects the speed of beam scanning.

[0104] Step 2: The antenna array control module 11 converts and decomposes the external control information or external control instructions into internal control information or internal control instructions.

[0105] Step 31: The antenna array control module 11 sends the internal control information or control instructions to the subarray wave control module 31: The antenna array control module 11 sends information or instructions to the subarray wave control module 31 at the same time through RS232, RS422, or RS485 protocol, and the subarray wave control module 31 feeds back relevant state information to the antenna array control module 11.

[0106] Step 41: At the same time as step 31, the antenna array control module 11 sends the internal control information or control instructions to the receiving / transmitting radio frequency module 21: The receiving / transmitting antenna array control module 11 sends information or instructions to the receiving / transmitting radio frequency module 21 through RS232, RS422, or RS485 protocol, and the receiving / transmitting radio frequency module 21 feeds back relevant state information to the antenna array control module 11.

[0107] Step 32: Time synchronization and frequency synchronization between subarray wave control module 31 and subarray wave control modules 32, 33, and 34: Time synchronization and frequency synchronization between subarray wave control module 31 and subarray wave control module 32, between subarray wave control module 32 and subarray wave control module 33, and between subarray wave control module 33 and subarray wave control module 34 are achieved through control lines 55, and the synchronization protocol includes but is not limited to RS232, RS422, RS485, or Ethernet.

[0108] Step 42: At the same time as step 32, time synchronization and frequency synchronization between transceiver module 21 and transceiver modules 22, 23, and 24: Time synchronization and frequency synchronization between transceiver module 21 and transceiver module 22, between transceiver module 22 and transceiver module 23, and between transceiver module 23 and transceiver module 24 are achieved through control lines 54, and the synchronization protocol includes but is not limited to RS232, RS422, RS485, or Ethernet.

[0109] Step 33: Subarray wave control modules 31, 32, 33, and 34 respectively calculate the array code table in real time or query the array code table stored in the memory.

[0110] Step 34: According to the array code table, subarray wave control modules 31, 32, 33, and 34 respectively issue configuration information or configuration instructions to liquid crystal phased array subarrays 411-41N1, 421-42N2, 431-43N3, and 441-44N4 at the same time, characterized in that the configuration information or configuration instructions are issued in full parallel, and each phased array unit is independently configured.

[0112] Step 43: At the same time as step 35, while completing phased array beamforming, transceiver modules 21, 22, 23, and 24 transmit and receive carrier waves.

[0113] The liquid crystal phased array itself is a passive phased array, and only phase modulation can be achieved in the unit or subarray. The traditional passive phased array adopts a centralized power distribution system. The liquid crystal phased array radio frequency module adopts a hybrid architecture of subarray-level power synthesis + unit-level phase modulation distribution (since there is power synthesis in the air interface and subarray-level calibration, the amplitude synchronization of the liquid crystal phased array module is realized in the antenna array control module). Therefore, the distributed control system proposed in the disclosure is also a hybrid architecture, and the amplitude calibration of the array is in the array-level antenna array control module, and the phase control in the unit level is in the subarray wave control module.

[0114] The driving of the T / R subarray of the active phased array based on the T / R chip or T / R component generally depends on the FPGA or dedicated Application Specific Integrated Circuit (ASIC) chip, and the control capability is limited by the Input / Output (I / O) interface resources. Therefore, a bus type or a serial mode such as a Serial Peripheral Interface (SPI) is generally adopted for control. The subarray control based on the liquid crystal phased array proposed in the disclosure adopts a full-parallel architecture. Therefore, unlike the active phased array, a strict synchronization or time delay calibration system is not required, the transmission efficiency is higher, and the technical advantages of the liquid crystal phased array can be better exerted.
