Description

Technical Field

[0001] The present invention relates to the technical field of phased array antennas, and in particular to a radio frequency array microsystem with a global online self-calibration function for transceiver channels. Background Art

[0002] With the rapid development of electronic technology and technology and the continuous advancement of microwave integration technology, phased array antenna technology has become more and more mature. Compared with traditional machine-scanned arrays, phased array antennas achieve rapid beamforming in the form of spatial power synthesis by changing the channel phase. They have the characteristics of beam agility, multi-beam forming, beamforming, high reliability, and high flexibility. They have been widely used in fields including satellite communications, 5G / 6G communications, space detection, radar guidance, etc. As the working frequency band of phased array antennas continues to expand and increase, the integration and channel scale of phased array antennas have also increased, and large-scale high-density integrated RF array microsystems have been derived, which have a large number of channels and extremely high integration. Therefore, the system has put forward higher requirements for the heat dissipation, volume and weight, profile height and other structural dimensions of phased array antennas, and the requirements for important electrical properties such as power, sidelobe level, gain and beam pointing are also getting higher and higher. At the same time, after leaving the darkroom test environment, the demand for online channel-level RF performance health monitoring of in-service products is becoming more and more urgent in view of long-term storage requirements.

[0003] High-density integrated RF array is a new type of phased array antenna technology. It adopts an integrated and lightweight design concept to integrate the components in the system with high density, realizing the integrated design of antenna array surface, feeding network, transceiver channel and structure, and thermal control. Antenna on chip (AOC) and packaged antenna (AIP) are the existing implementation methods of high-density integrated RF array. The antenna on chip uses semiconductor technology to integrate the antenna array surface and circuit on a chip, and the packaged antenna uses packaging technology to integrate the antenna array surface in the packaging material carrying the chip. Although both methods have achieved lightweight and integrated design, it is difficult to meet the high-power density working requirements. After the high-power phased array antenna system is highly integrated, severe heat density concentration problems will occur, resulting in the degradation of antenna system performance, and ultimately unable to meet the use requirements.

[0004] Furthermore, to ensure electrical performance, the phased array antenna must calibrate the amplitude and phase of each channel array element before leaving the factory. The amplitude and phase accuracy of all channel-related array elements are important factors affecting the electrical performance of the phased array antenna. The phased array antenna controls the compensation values ​​of the phase shifter and attenuator through the wave control system, and performs differentiated compensation for the amplitude and phase of the array, thereby achieving the best radiation performance of the phased array antenna. After delivery to the customer, the phased array antenna also needs to be tested and diagnosed from time to time, but due to limitations such as the test environment, test equipment, and product storage environment, channel-level online performance health monitoring is usually not possible. When the product encounters performance problems, it often needs to be returned to the factory for disassembly and secondary calibration testing.

[0005] Online monitoring of the performance of the RF transmission channel of a phased array antenna means that during the use of the phased array antenna, the amplitude and phase of the array can be tested at any time and anywhere; failed array elements can be diagnosed and screened out, and performance can be evaluated online; the amplitude and phase of each channel of the array can be independently measured and adjusted to ensure good radiation characteristics of the phased array antenna. This will enable health monitoring of the entire life cycle of the phased array antenna. At present, depending on the injection or acquisition point of the measurement signal, the basic methods for monitoring the array of phased array antennas are divided into two types: "internal monitoring" and "external monitoring". The existing traditional near-field and far-field calibration methods such as commutation method, modulation method and mutual coupling method all fall into the category of these two basic methods.

[0006] However, whether it is "external monitoring" or "internal monitoring", external computers and supporting test equipment are required, including computers, control equipment, vector network analyzers, signal sources, spectrum analyzers, etc. Some systems that can realize self-calibration functions rely on complex analog and digital circuit designs at the back end to realize sub-array-level performance monitoring and calibration in the digital domain. In the performance monitoring and calibration process, multi-level test errors of the feed network, RF cables, and analog / digital conversion circuits are mixed, and global channel performance monitoring and calibration cannot be achieved. At the same time, with the improvement of system integration, the increase in device coupling and channel coupling further increases the difficulty of calibration, which makes the realization of array monitoring and calibration functions highly dependent on external resources and human and technical capabilities, resulting in extremely high testing costs and poor online linearity in evaluating the performance of phased array antennas.

[0007] At present, the monitoring and calibration compensation methods of phased array antenna arrays are mostly implemented by relying on external test equipment, or by implementing multi-channel sub-array transceiver calibration in the digital domain through analog-to-digital conversion. The process is cumbersome and the method is complex. Due to the limitations of the environment, equipment, site and technical personnel, it is impossible to independently realize the online self-calibration of the transceiver channels of large-scale RF arrays and the amplitude and phase performance monitoring of the transceiver channels. Summary of the invention

[0008] The purpose of the present invention is to provide a radio frequency array microsystem with a global online self-calibration function for the transceiver channels, so as to solve the problem that the current methods for phased array antenna surface monitoring and calibration compensation are complicated, limited by the environment, equipment, site and technical personnel, and cannot independently realize the online self-calibration of the transceiver channels of large-scale radio frequency arrays.

For each channel of a single link, the calculation is performed serially. After each channel is calculated, the phase of the channel of all links and the calculation completion enable signal are sent to the phase compensation module until all channels are calculated.

[0077] The first step is to power on and load the software;

[0078] The second step is to perform initialization configuration. After successful initialization, wait for the third step. If unsuccessful, initialize again.

[0079] The third step is to wait for the external communication interface control command input and determine the validity of the command. If it is valid, proceed to the next step; otherwise, wait again.

[0080] The fourth step is to execute different functional modules according to the instructions:

[0081] Temperature detection module: After receiving the temperature monitoring command, this module is executed. After receiving the command input, the temperature detection module reads the online temperature from the temperature sensor and sends the obtained temperature back to the external communication interface for output;

[0082] Flash read, write and erase module: After receiving the Flash read, write and erase instructions, this module is executed. After receiving the instructions, the Flash read, write and erase operations are performed according to the instructions and the readback information is output through the external communication interface;

[0083] Channel calibration module: After receiving the channel calibration command, this module is executed.

[0084] Serial phase solution module: After receiving the serial phase solution, this module is executed. According to the received beam requirements, the phase solution is performed and the solved single-channel phases are sent serially in sequence;

[0085] Channel power-on module: After receiving the channel power-on command, this module is executed. The power-on function of the corresponding channel is executed according to the command;

[0086] Enable signal generation module (ACK, T, R, LOAD signals): After receiving the enable signal of the external communication receiving input, this module is executed. The input signal is processed according to the instruction execution and then sent down. The processing content includes sampling, forwarding, delay, etc.
