[0003] However, the above-mentioned darkroom test method is limited by hardware equipment, and cannot correctly evaluate the performance of a large antenna array, and can only test the data of one antenna in one state at a time. For multi-antenna or multi-state measurement, manual replacement is required. Frequent in and out of the dark room
[0004] For the application of multiple antennas, it is necessary to evaluate the performance of each antenna. The above-mentioned darkroom test method has low test efficiency and high cost, and is limited by space and hardware equipment and other conditions and cannot accurately evaluate the performance of multiple antennas.

The embodiment of the invention relates to an antenna array testing method and system. The method comprises the following steps of determining a plurality of test data sent by the same target antennaand received by a to-be-tested antenna array under different test conditions, determining target data sent by a target antenna to the antenna array, and determining a single direction direction finding index of the antenna array according to the plurality of test data and the target data. A motor turntable is adopted to drive the antenna array to rotate, inconvenience of manual direction and frequency band adjustment is avoided, the measurement efficiency is improved, the limitation of measuring the antenna array in a secret chamber is eliminated, and the measurement of the performance and direction-finding precision of the antenna array in a complex environment is enhanced.
Description
technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and system for testing an antenna array. Background technique [0002] The traditional evaluation of antenna performance is mainly by putting the antenna into a professional darkroom to test parameters such as antenna gain, half-power beam width and pattern, and then technicians analyze the measured parameters to theoretically evaluate the effect of the antenna in actual application scenarios. [0003] However, the above-mentioned darkroom test method is limited by hardware equipment, and cannot correctly evaluate the performance of a large antenna array, and can only test the data of one antenna in one state at a time. For multi-antenna or multi-state measurement, manual replacement is required. Go in and out of the dark room frequently. [0004] For the application of multiple antennas, it is necessary to evaluate the performance of each antenn...
