High Precision Antenna Far-Field Measurement System Based on Pulse Trigger and Closed Loop Control Technology

This paper introduces a kind of high-precision far-field measurement system for antennas, which is based on pulse trigger and closed-loop control technology. The schematic structure and measurement principle of the system is described. In addition, communication methods, precision control and program design are introduced also. All instruments in this system are controlled by program through LAN bus, achieving automatic and remote measurement. Positioning accuracy of this system is less than 0.008°, which is much better than the current industrial standard 0.03°. The good performance and stability of the system are verified through testing and evaluation, indicating the validity of the proposed measurement method and system design strategies.
