Problems solved by technology

However, in the existing patent CN 103915687A, the method of numbering the transceiver modules by using the special numbering control lines in the array will cause too many wirings of the transceiver modules, which not only increases the complexity of the array design, but also leads to changes in the reliability and maintainability of the entire array. Poor; In addition, in the face of multiple area array integration expansion and function expansion, it is necessary to reorganize the numbering rules, which is not suitable for improvement and expansion in similar directions

Embodiment 1

[0033] In this example such as figure 1 As shown: the digital active phased array includes an antenna array 100 and a back-end device 200, the antenna array 100 is composed of 8 transceiver modules 101, and the 8 transceiver modules 101 are arranged in sequence in the horizontal direction, and the back-end device 200 includes a DBF module 201 and the beam control subsystem 202, the transceiver module 101 of the antenna array 100 is connected to the DBF module 201 of the back-end device 200 through an optical fiber, and the DBF module 201 of the back-end device 200 is connected to the beam control subsystem 202 through a high-number serial port , the generation duty cycle of the beam control subsystem 202 of the backend device 200 is respectively connected to the DBF module 201 and the transceiver module 101 of the antenna array 100 through the timing control bus; the transceiver module 101 is composed of 8 transceiver channels, and the 8 transceiver modules The channels are ar...

Embodiment 2

[0041] In this embodiment, the composition of the digital active phased array and the connection relationship of the internal modules remain the same figure 1 As shown, only the steps of the number identification method of the transceiver module are changed, the coding software is canceled, and the one-to-one correspondence between the hardware connection relationship between the DBF module of the back-end device and the bidirectional optical fiber interface of the transceiver module is used to determine; the specific implementation Steps such as image 3 Shown:

[0042] When the system is powered on, power is supplied to the back-end equipment 200 first. Before the current transceiver cycle, the beam control subsystem 202 in the back-end equipment 200 is sorted in sequence according to the spatial positions of the transceiver channels of the transceiver module 101 inside the antenna array 100 to form a whole The total length of the transceiver module 101 of the antenna array...

Abstract

The invention provides an on-line automatic identification method for a spatial position number of a receiving and transmitting module of a digital active phased-array antenna array plane, which comprises the following steps of: digitizing and software-converting number information, placing the number information in a working instruction data packet of the receiving and transmitting module by using an original communication interface of the receiving and transmitting module, and flexibly adjusting the bit length of the number information according to the scale of the antenna array plane. A small-scale array plane can be randomly selected and set in an existing array plane range, and a plurality of different array planes placed at fixed positions can be uniformly organized, so that flexible configuration of apertures, multiple frequency bands and other functions is realized, and the system adapts to the digital, multifunctional and software development direction of a phased array system and has a wide application prospect. The number of control interfaces of the transceiver module and the number of control cables in the antenna array plane are reduced while interchangeability of the transceiver module in the antenna array plane is not affected, the design integration degree of the transceiver module and the control cables is improved, and reliability and maintainability of the whole antenna array plane are improved.

Description

technical field [0001] The invention relates to the field of digital active phased array antenna array transceiver module field. Background technique [0002] The beam scanning of the active phased array antenna array is realized by phase shifting between the transmitting and receiving channels; in order to reduce interference in the radar system, the antenna array has certain requirements on the beam side lobes, and beam forming is required, and the beam forming can be adjusted by adjusting the channel The radar system generally also has the AGC function (P153, the third edition of the Radar Handbook of the Electronic Industry Press, 2010), that is, the transmit power and receive gain are adjusted in real time according to the size of the reflected energy of the target, so the active front transceiver In addition to the phase shifting function, the transceiver channel of the module also has the channel gain control function. When the antenna front is working, it is necessar...
