Method for implementing near field data extraction of phased array antenna

Abstract

The invention discloses a method for implementing near field data extraction of a phased array antenna. The method mainly solves the problem that in the prior art, the process of data extraction of the phased array antenna is complicated and the probability of errors is large due to the fact that the environments of a test and official use are different. The method judges whether a channel is thelast channel through steps of communication connection, antenna installation, wave control configuration, vector network analyzer configuration, configuration data extraction, channel alignment, channel power up, other channel turn-off or maximum attenuation, and channel data extraction; and if the channel is not the last channel, the channel returns to channel alignment to continue execution, andif the channel is the last channel, the data extraction result is saved. According to the above scheme, the purposes that data obtained by the data extraction method is more accurate, operations areautomatically completed through adopting software, the data extraction process is simple, the data extraction speed is faster and the probability of data errors is smaller are achieved, and the methodhas high practical value and popularization value.

Description

technical field [0001] The invention belongs to the technical field of radar communication, and in particular relates to a method for realizing near-field data extraction of a phased array antenna. Background technique [0002] The 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. Controlling the phase can change the direction of the maximum value of the antenna pattern to achieve the purpose of beam scanning. In special cases, it is also possible to control the sidelobe level, the position of the minimum value and the shape of the entire pattern, such as obtaining a cosecant square pattern and performing adaptive control on the pattern, etc. When the antenna is rotated mechanically, the inertia is large and the speed is slow. The phased array antenna overcomes this shortcoming, and the scanning speed of the beam is high. Its feed phase is generally controlled by ...
