Abstract

The invention discloses a system for calibrating a TR component transceiving channel through antenna spatial coupling. Due to a mode of realizing calibration by burying coupling lines on antennas, the weight of the system can be greatly reduced, and the complexity is reduced. A sum-difference network is connected with a plurality of transceiving channels; the transceiving channels are connected to the antennas through cables. Each transceiving channel can be independently controlled, and consists of a phase shifter, an attenuator, an amplifier and a filter; and sum and difference outputs of the sum-difference network are connected with a rear-end receiver.

Description

Technical field: [0001] The present invention relates to an amplitude and phase calibration system for a transceiver channel of a receiver. Background technique: [0002] The traditional TR antenna front-end uses a coupling line buried in each radiating unit, and enters the calibration transceiver channel through the coupling line. This calibration method has complicated circuits and cannot effectively reduce weight. Invention content: [0003] The purpose of the present invention is to provide a system with simple structure, small workload, less data volume, and accurate calibration data through spatial coupling between antennas to calibrate the transmission and reception channels of TR components. [0004] The present invention is achieved like this: [0005] A system for calibrating the transceiver channels of TR components through spatial coupling between antennas, characterized in that the sum and difference network is respectively connected to several antennas CH1~C...
