Abstract

The invention discloses a phased array antenna testing method and a phased array antenna testing system. The test parameters including item identification and antenna state parameters are obtained from an input device, and then the corresponding optimal test range is determined based on the test parameters. , further determining test state parameters corresponding to the antenna state parameters and the test range, and finally controlling the phased array antenna to be tested to work according to the test state parameters to obtain corresponding test results. Since the technical solution of the present application can determine the corresponding preferred test range according to different test items and antenna state parameters, a test result with high precision can be obtained on the basis of a small amount of test data. It can be seen that the embodiment of the present application The technical scheme in has the technical effect of improving the testing efficiency of the phased array antenna on the basis of ensuring the high precision of the testing.

Description

technical field [0001] The invention relates to the technical field of phased array antenna testing, in particular to a phased array antenna testing method and a phased array antenna testing system. Background technique [0002] A phased array antenna refers to an antenna that changes the shape of the pattern by controlling the feeding phase of the radiating elements in the array antenna, and controlling the phase can change the direction of the maximum value of the antenna pattern to achieve the purpose of beam scanning. [0003] Before the phased array antenna is applied, it is usually necessary to measure the phased array antenna in different states, different ranges, and different scales under different working modes. Different test contents correspond to different test items. For example, the structure of a phased array antenna is usually an array composed of tens of thousands of units to form an antenna array. Different units usually correspond to different signal proc...
