Description

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

[0001] The embodiments of the present disclosure relate to, but are not limited to, the field of liquid crystal phased array technology, and in particular to a distributed control method, system, and device for a liquid crystal phased array antenna radio frequency module. Background Art

[0002] With the rapid rise of 5G millimeter-wave communications and broadband low-orbit satellite communications, phased array antennas have experienced unprecedented growth and are widely used in satellite communications and radar systems. Phased array antenna beam steering primarily relies on receiving beam steering commands from a host computer. A beamforming algorithm and calibration unit calculate the phase difference and amplitude of the phase shifter module or wireless transceiver (T / R) chip to achieve phased array antenna beam steering.

[0003] Traditional phased array antennas generally use a centralized beam steering scheme, characterized by a beam steering module that centrally calculates the amplitude and phase values ​​of each antenna element in the array and then transmits the resulting amplitude and phase control code to each element. This scheme requires minimal hardware and is suitable for planar array antennas with a small number of elements and relatively simple calculations. However, for distributed array antennas with a large number of elements and relatively complex calculations, the calculation time is often long, seriously affecting the beam scanning speed.

[0032] A liquid crystal phased array antenna consists of a phase shifter, a metal ground (including a slot structure), a dielectric substrate, and a metal radiating patch. The operating principle of a liquid crystal phased array antenna is briefly described as follows: By applying different voltage signals to control the deflection state of the liquid crystal, when an electromagnetic wave signal radiates outward through the adjusted liquid crystal cell, the phase shifter unit corresponds to different phase delays under different voltage signals. By controlling the phase delay parameters, the electromagnetic waves couple with each other in the external space, forming a main beam in the target direction, completing the transmission of the electromagnetic signal. Furthermore, external electromagnetic waves pass through the radiating patch, the metal ground slot structure, and the adjusted liquid crystal cell. By applying different voltages to control the deflection state of the liquid crystal, signal processing with different phase delays of the external electromagnetic wave is achieved, thereby fully receiving the signal from the external space and completing the electromagnetic signal reception.

[0100] The antenna array control module 11 is connected to the sub-array beam control module 31 via a control line 53. The control protocol generally includes but is not limited to RS232, RS422, or RS485.

The synchronization protocol includes but is not limited to RS232, RS422, RS485, or Ethernet.

The sub-array wave control modules 32 are connected to the liquid crystal phased array sub-arrays 421 to 42N2 in the transmitting liquid crystal phased array 42 via N2 groups of control lines 57, respectively.

The control lines 53 are fully parallel, and each group of control lines 53 has at least M×K independent parallel drive and control bits.

[0102] The control method of the distributed control system of the liquid crystal phased array RF module in the above example is described below with reference to FIG6 .

[0103] Step 1: The antenna array control module 11 receives external control information or external control instructions: the external control information or external control instructions mentioned here can come from a baseband device / module, a beacon receiver, a combined inertial navigation module, a temperature sensor, or other external devices or equipment.

[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 internal control information or control instructions to the sub-array beam control module 31: The antenna array control module 11 simultaneously sends information or instructions to the sub-array beam control module 31 through protocols such as RS232, RS422, or RS485, and the sub-array beam control module 31 feeds back relevant status 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 internal control information or control instructions to the transceiver / RF module 21: the transceiver antenna array control module 11 sends information or instructions to the transceiver / RF module 21 through protocols such as RS232, RS422, or RS485, and the transceiver / RF module 21 feeds back relevant status information to the antenna array control module 11.

[0107] Step 32: The sub-array beam control module 31 performs time synchronization and frequency synchronization with the sub-array beam control modules 32, 33, and 34: The sub-array beam control module 31 and the sub-array beam control module 32, the sub-array beam control module 32 and the sub-array beam control module 33, and the sub-array beam control module 33 and the sub-array beam control module 34 respectively achieve time synchronization and frequency synchronization between the sub-array beam control modules via the control line 55. The synchronization protocol includes but is not limited to RS232, RS422, RS485, or Ethernet.

[0108] Step 42: At the same time as step 32, the transceiver / RF module 21 performs time synchronization and frequency synchronization with the transceiver / RF module 22, the transceiver / RF module 23, and the transceiver / RF module 34: the transceiver / RF module 21 and the transceiver / RF module 22, the transceiver / RF module 22 and the transceiver / RF module 23, and the transceiver / RF module 23 and the transceiver / RF module 24 respectively realize time synchronization and frequency synchronization between the transceiver / RF modules through the control line 54, and the synchronization protocol includes but is not limited to RS232, RS422, RS485, or Ethernet.

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

[0110] Step 34: Based on the array code table, subarray wave control modules 31, 32, 33, and 34 simultaneously send configuration information or configuration instructions to liquid crystal phased array subarrays 411-41N1, 421-42N2, 431-43N3, and 441-44N4, respectively. This configuration information or configuration instructions are sent in full parallel, and each phased array unit is independently configured.

[0111] Step 35: The liquid crystal phased array sub-arrays 411 - 41N1 , 421 - 42N2 , 431 - 43N3 , and 441 - 44N4 respectively and simultaneously drive the liquid crystal cells in each phased array unit, thereby simultaneously achieving phased array beamforming.

[0112] Step 43: Simultaneously with step 35, while completing phased array beamforming, the RF transceiver module 21, the RF transceiver module 22, the RF transceiver module 23, and the RF transceiver module 24 transmit and receive carriers.

[0113] The liquid crystal phased array itself is a passive phased array, and only phase modulation can be achieved within the unit or sub-array. Traditional passive phased arrays all use a centralized power distribution system. The liquid crystal phased array RF module adopts a hybrid architecture of sub-array-level power synthesis + unit-level phase modulation distribution (due to the existence of air interface power synthesis and sub-array-level calibration, the amplitude synchronization of the liquid crystal phased array module is implemented in the antenna array control module). Therefore, the distributed control system proposed in this disclosure also has a hybrid architecture, with the array amplitude calibration in the array-level antenna array control module and the unit-level phase control in the sub-array-level sub-array wave control module.

[0114] Active phased arrays based on T / R chips or T / R components typically rely on FPGAs or dedicated application-specific integrated circuits (ASICs) to drive their T / R subarrays. Their control capabilities are limited by input / output (I / O) interface resources, and therefore are often controlled using bus or serial methods such as a serial peripheral interface (SPI). The subarray control based on a liquid crystal phased array proposed in this disclosure uses a fully parallel architecture. Therefore, unlike active phased arrays, which require strict synchronization or delay calibration systems, this system offers higher transmission efficiency and better leverages the technical advantages of liquid crystal phased arrays.
