System for calibrating TR component transceiving channel through antenna spatial coupling

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. 本发明为通过天线空间耦合来对TR组件收发通道进行校准的系统，解决通过在天线上埋耦合线进行校准的模式，可以大大减轻系统的重量、降低复杂度。和差网络与若干收发通道相连，收发通道通过电缆连接到天线。每个收发通道可以独立控制且均由移相器、衰减器、放大器、滤波器组成，和差网络的和、差输出与后端接收机连接。
