Description

Technical Field

[0001] This invention belongs to the technical field of phased array radar components, specifically a multi-channel TR component. Background Technology

[0002] The TR (Transmitter and Receiver) module is a core component of an active phased array radar. The TR module receives and analyzes the beam control code from the main control chip, performs level conversion and signal amplification, and then drives the radio frequency chip to achieve the transmission and reception of microwave signals.

[0003] Each active phased array radar consists of tens of thousands of microwave signal transceiver channels. Each microwave signal transceiver channel is composed of a beam control chip. The internal structure of the beam control chip is as follows: Figure 1 As shown, the system includes a beam control module connected to the main control chip at the front end and an RF chip connected to the back end of the beam control module. The beam control module typically includes a receiving circuit, a beam control code processing circuit, and a level conversion and driving circuit. The input of the receiving circuit is connected to the main control chip, and its output is connected to the input of the beam control code processing circuit. The input of the level conversion and driving circuit is connected to the output of the beam control code processing circuit, and its output is connected to the RF chip. The receiving circuit communicates with the main control chip, receiving the beam control code sent by the main control chip. The beam control code processing circuit reads the beam control code from the receiving circuit and parses it to obtain information about the control beam control code. The level conversion and driving circuit performs level conversion and signal amplification, outputting the beam control code to the RF chip to drive it. Early phased array radars integrated a single microwave signal transceiver channel, i.e., a beam control chip, into a single TR component, forming a single-channel TR component.

[0004] To achieve miniaturization and weight reduction of radar arrays, the current trend is to integrate multiple microwave signal transceiver channels, i.e., multiple beam control chips, into a single TR module, forming a multi-channel TR module, such as 4-channel, 8-channel, or 16-channel TR modules.

[0005] Figure 2 The diagram shows an example of the structural block diagram of an existing multi-channel TR module. Each beam control chip within the TR module is directly connected to the enable control signal terminal (SW) and beam control code terminal of the main control chip. The main control chip and the beam control chips communicate via serial port. Taking the common SPI format as an example, the serial communication speed is typically 10Mbps, with a maximum of 20Mbps. The main control chip writes the beam control code controlling microwave signal reception and transmission to each beam control chip in the TR module one by one. The time taken for the main control chip to write the beam control code to one TR module is the sum of the writing times of all beam control chips. The total update time of the radar array beam control data is the sum of the writing times of all TR modules.

[0006] On the one hand, the data transmission speed is low because the main control chip and the beam control chip communicate via serial port. On the other hand, the main control chip writes the beam control code to each beam control chip one by one. For a phased array radar with tens of thousands of TR components, the overall data update time is long, and the radar array beam control data update speed is slow, which seriously affects the accuracy and flexibility of phased array radar detection. Summary of the Invention

[0025] The receiving data signal port 3102 of the serial communication unit 31 is connected to the wave control data output terminal 23 of the main control chip 2 through the second LVDS interface 372, and the sending data port 3103 of the serial communication unit 31 is connected to the readback data port 24 of the main control chip 2 through the third LVDS interface 373.

[0026] The input terminal of the instruction parsing data buffer unit 32 is connected to the data output terminal 3104 of the serial communication unit 31, and its output terminal is connected to the data receiving terminal 3301 of the data processing unit 33.

[0027] The input terminal 3401 of the output driving circuit 34 is connected to the output terminal 3303 of the data processing unit 33, and its beam control code output terminal 3402 is connected to the beam control code terminal of each beam control chip 1. The beam control code state sampling output terminal 3403 of the output driving circuit 34 is connected to the data acquisition input terminal 3304 of the data processing unit 33.

[0032] 1. Fast data transmission: This invention uses LVDS interface communication, with a communication speed of up to 400Mbps, which greatly improves the data transmission speed;

[0033] 2. Short beam control code writing time: This invention employs a simultaneous beam control code writing method for multiple beam control chips within the same TR component.

By increasing the data transmission speed and improving the wave control code writing efficiency, the timeliness of radar array wave control data updates is ensured, effectively improving the accuracy and flexibility of phased array radar detection.

[0071] like Figure 4 As shown, the serial communication unit 31 includes a shift register 311, a data frame header parsing circuit 312, a data frame tail parsing circuit 313, a data receiving control circuit 314, a data verification circuit 315, a data buffer sending circuit 316, a data frame synthesis circuit 317, and a data frame sending circuit 318.

[0072] The clock input terminal 3111 of the shift register 311 corresponds to the clock signal port 3101 and is used to connect to the first LVDS interface 371. Its receiving data input terminal 3112 corresponds to the receiving data signal port 3102 and is used to connect to the second LVDS interface 372.

If any one of the three circuits fails the test, the received data frame is discarded.

[0084] Data verification circuit 315: Performs algorithm verification on the received data, using a bitwise XOR operation as agreed upon in the verification algorithm. The verification result is then sent to data receiving control circuit 314.

[0085] Data buffering and transmitting circuit 316: Receives the wave control data sent by the data receiving control circuit 314 and buffers the received data according to the first-in-first-out principle. The received wave control data is then sent to the next stage circuit through the data output terminal 314.
