Description
Technical Field
The invention belongs to the technical field of phased array radars, and particularly relates to a TR component beam control module based on built-in data verification.
Background
The TR component is a core component of a modern phased array radar and is responsible for transmitting and receiving microwave signals in the radar. The beam steering module is an important component of the TR module. As shown in fig. 1, the TR module generally includes a receiving circuit, a wave control code processing circuit, and a level converting and driving circuit. The input end of the receiving circuit is connected with the main control chip, and the output end of the receiving circuit is connected with the input end of the wave control code processing circuit; the input end of the level conversion and drive circuit is connected with the output end of the wave control code processing circuit, and the output end of the level conversion and drive circuit is connected with the radio frequency chip. The beam control module receives the wave control code sent by the main control chip, analyzes signals for controlling microwave transmission and reception from the wave control code, and is used for driving the radio frequency chip after level conversion and signal amplification. The receiving circuit is generally constituted by a data receiving shift register or the like.
In the prior art, the TR module beam control module, as described in the chinese patent application specification "a wave control processing module for phased array radar" (application No. 201910371552.6, published as 2019.07.30), includes a first FPGA processor, a second PFGA processor, and a radio frequency TR module connector; the first FPGA processor is respectively connected with the radio frequency TR module connector and the second FPGA processor; the second FPGA processor is connected with an SRAM memory and is also connected with an external upper computer; and the second FPGA processor is used for storing the radio frequency phase shift and attenuation data of the radio frequency TR module and the corresponding beam pointing control code in an SRAM memory according to address information, receiving a beam control instruction from an upper computer, analyzing attenuation and phase shift information required by the radio frequency TR module, looking up a table from the SARM memory to obtain the corresponding beam pointing control code, and transmitting the corresponding beam pointing control code to the first PFGA processor. The first FPGA processor is used for carrying out phase shift and attenuation control on each path of radio frequency TR module connected on the radio frequency TR module connector according to the beam pointing control code from the second FPGA processor.
The second FPGA processor in the above patent application document combines the functions of the receiving circuit and the wave control code processing circuit in the TR module beam control module shown in fig. 1. It can be seen from the process that the beam control instruction from the upper computer is received from the second FPGA processor for analysis, and the receiving circuit is communicated with the main control chip of the upper computer and only simply and directly receives the beam control instruction from the upper computer. However, in the communication between the main control chip and the receiving circuit, a certain bit error rate inevitably exists, so that an error exists in the transmission of the beam control instruction, and the working reliability of the rear-stage radio frequency chip and the detection precision of the whole phased array radar are affected.

Detailed Description
As shown in fig. 2, the TR module based on built-in data verification of the present invention includes:
the receiving circuit 1 with the input end connected with the main control chip 4, the level conversion and drive circuit 3 with the output end connected with the radio frequency chip 5, and the wave control code processing circuit 2 with the input end connected with the output end of the receiving circuit and the output end connected with the input end of the level conversion and drive circuit.
The receiving circuit 1 includes a data receiving shift register 11 and a data checking unit 12, and is configured to communicate with the main control chip 4, perform data checking, and receive the wave control code sent by the main control chip 4.
The receiving circuit 1 and the main control chip 4 can communicate in any form of SPI, I2C, UART, or the like.
And the wave control code processing circuit 2 is used for reading the wave control code from the receiving circuit 1, analyzing the wave control code and acquiring a processing mode of the radio frequency microwave signal.
The processing mode of the radio frequency microwave signals is divided into two modes of signal receiving or signal transmitting, and the amplitude and the phase of the microwave signals are processed to a certain extent according to the detection requirement of the whole radar signals.
The level conversion and driving circuit 3 is used for level conversion and signal amplification to drive the radio frequency chip 5.
Usually, the microwave rf chip operates in a negative voltage mode, and the wave control code sent by the main control chip is a TTL signal. The signal for driving the microwave rf chip must be in a negative voltage form, so the beam control circuit of the present invention needs to convert the TTL signal with a positive voltage into a negative voltage driving signal with the same meaning. The module receives TTL signals of the wave control code processing circuit for carrying out corresponding processing on microwave signals, converts the TTL signals into negative voltage signals through the level conversion circuit, and further amplifies the converted negative voltage signals into electric signals capable of driving a radio frequency chip.
Those skilled in the art will appreciate that the master control chip 4 is not included in the TR assembly and is typically part of a phased array radar wave controller.
As shown in fig. 2, the receiving circuit 1 includes a data receiving shift register 11.
The receiving circuit 1 further comprises a data verification unit 12.
The input end 121 of the data checking unit is connected to the output end of the data receiving shift register 11, and the output end 122 of the data checking unit is connected to the input end of the wave control code processing circuit 2.
The data checking unit 12 further includes a checking feedback terminal 123; and a verification feedback end of the data verification unit is connected with a feedback end 41 of the main control chip.
As shown in fig. 3, the data checking unit 12 is configured to perform algorithm checking on the received wave control code according to a checking algorithm agreed with the main control chip 4, and perform corresponding processing according to a checking result. If the verification is successful, the received wave control code is correct, and the correct wave control code is transmitted to the wave control code processing circuit 2 at the later stage. If the verification fails, the verification failure information is transmitted to the main control chip 4 through the corresponding signal port, i.e., the verification feedback terminal 123, and the main control chip 4 determines the transmission of the subsequent wave control code.
Data checking algorithms include, but are not limited to: parity, cyclic Redundancy Check (CRC), etc. The circuitry for implementing these algorithms is well known in the art and the data verification unit 12 may be implemented using any of the known techniques. This is not described in detail herein.
