Description
Technical Field
The invention relates to the technical field of active phased array antennas, in particular to a sandwich type internal calibration structure integrated inside a multi-channel compact T/R assembly.
Background
The calibration of the T/R assembly of the existing active phased array antenna is mainly performed, and the external calibration sequentially calibrates the initial amplitude and the phase of a receiving and transmitting channel of each T/R assembly by moving an external calibration antenna. The external calibration mainly comprises a calibration vector network analyzer, a radio frequency cable, a calibration antenna, a scanning frame, a darkroom environment and the like. The special test equipment and the test environment are very complex for the test work of the active phased array, and have high cost and high environmental requirements. Part of the T/R assembly adopts an internal calibration active phased array, and due to the increase of internal calibration functions and structures, the T/R assembly is increased in size and weight, and the realization of a miniaturized low-profile phased array is more difficult.
The test of the active phased array antenna faces the calibration procedure of the T/R assembly, and the calibration mode of the T/R assembly is also a difficulty of the design of the compact low-profile active phased array. The current calibration mode of the T/R assembly is mainly divided into an external calibration mode and an internal calibration mode. (1) In an external calibration mode, a calibration antenna is fixed on a near-field scanning frame in a darkroom environment, and a radio frequency cable is used for connecting the calibration antenna and one port of a calibration vector network analyzer. After all the T/R components are synthesized by the microwave synthesis network, a radio frequency cable is used for connecting the joint of the microwave synthesis network and the other port of the calibration vector network analyzer. And the initial amplitude and the phase of each T/R component receiving and transmitting channel are sequentially tested by digitally controlling the movement of the scanning piece, so that the calibration test is completed. (2) In a conventional internal calibration mode, an internal calibration module is added when the T/R assembly is designed, the internal calibration module and the T/R assembly are fixed together, and the calibration ports of the T/R assembly and the internal calibration module are connected through an adapter or a cable. And the switch of each T/R component receiving and transmitting channel is controlled by the wave control equipment in sequence, so that the calibration test is completed.
At present, the near field external calibration method is a main calibration method of the phased array T/R assembly at present, and can effectively improve the calibration precision, but has high requirements on external calibration scanning equipment and testing equipment, and has high cost. External field calibration outside of the darkroom environment is difficult to achieve, resulting in the need for return-to-darkroom recalibration of the active phased array after prolonged use. As the number of phased array antenna elements increases, the physical size of the T/R components needs to be further reduced, and the space for the circuit layout of the radio frequency circuitry and control circuitry is strained. The T/R assembly internal calibration method is a development trend of phased array antenna array plane calibration, and is simple in calibration mode and beneficial to periodic calibration of an external field. However, the size of the calibration module in the conventional T/R assembly is larger, and the larger volume of the T/R assembly is occupied, which is contrary to the compact antenna array surface size.
