Abstract

The invention discloses a fast calibration test system and method for a phased-array antenna, belongs to the technical field of antenna measurement, relates to a near-field test system, and particularly relates to fast calibration and directional diagram test of the phased-array antenna. The system comprises an upper computer module, a switch module, a synchronous control module, a signal source module, a power amplifier module, a low noise amplifier module, a to-be-tested phased array antenna, a power supply module, a calibration control module, a scanning module, a signal conditioning module and a vector network module. Bases on pulse synchronous control, the loading delay of wave control codes is shortened by using real-time calculation, the channel calibration of the phased-array antenna under various frequencies can be completed through two rounds of scanning, and a directional diagram test of the phased-array antenna under the combination of various frequencies and directional angles can be covered through one round of scanning.

Description

technical field [0001] The invention relates to a phased array antenna rapid calibration test system and method, which belong to the technical field of antenna measurement, relate to a near-field test system, and particularly relate to the phased array antenna rapid calibration and pattern test. Background technique [0002] Due to the characteristics of beam agility, phased array antennas have significant advantages in fast pointing, shape agility, spatial power combining, and spatial filtering. With the advancement of integrated circuits and micro-assembly processes, the size and cost of phased array antennas have been continuously reduced, and they have been increasingly widely used in radar, communication and other fields. [0003] The phased array antenna is composed of the antenna array, T / R components, power distribution feed network and heat conduction structure. Due to the differences in the consistency of the channel indicators of the T / R components, and the errors...
