Problems solved by technology

And because the array element coordinates of each antenna board have been changed, it is necessary to manually re-array and recalibrate the amplitude and phase values, and then all single-board test items need to be verified again
This process is complicated and time-consuming, sometimes lasting more than ten days or even months

Abstract

The invention provides a phased-array antenna automatic array splicing method and a phased-array antenna. The method comprises the steps: a control module acquires a coordinate corresponding to each array element on a basic antenna board according to the attribute and origin determination strategy of the basic antenna board; the control module acquires coordinates corresponding to each array element on the other antenna boards according to the splicing relationship between the other antenna boards and the basic antenna board; the control module sends the coordinate, the current off-axis angleand the current rolling angle of each array element to the corresponding antenna board; and each antenna board respectively calculates the standard phase of each array element according to the received coordinates of each array element, the current off-axis angle and the current rolling angle so as to complete array splicing. By automatically calculating the coordinate origin of the antenna boardand the distance between the array elements, the amplitude and the phase compensation value between the antennas can be quickly and automatically measured and then guided to be controlled, so that automatic array splicing of the phased-array antenna can be realized, and unnecessary manpower and time loss is reduced.

Description

technical field [0001] The present application relates to the field of antennas, in particular to a phased array antenna automatic formation method and a phased array antenna. Background technique [0002] With the increase of radar applications and increasingly powerful functions, people's requirements for its functions are also increasing. Requirements include: target detection range, accuracy, and anti-stealth. The increase in functional requirements leads to an increasing number of antenna boards applied to the complete phased array antenna. [0003] In order to make the phased array antenna including multiple antenna boards meet the requirements of functionality, accuracy, and stability, it is necessary to test the phased array antenna. From the antenna single board to the process of assembling the whole machine, the test of each antenna board is divided into two stages, the first stage is the single board test, and the second stage is the whole machine test. Single ...
