Abstract

The invention relates to an X-band high-isolation radio frequency transceiver system and a channel consistency calibration method thereof, and relates to the technical field of radars, and the method comprises the steps: a calibration mode is set, and a calibration antenna receives an echo signal; the received echo signal is injected into a first-stage single-pole double-throw switch in the switch switching array network, then is subjected to low-noise amplification and then is input into a second-stage single-pole double-throw switch, and the signal is input into a down-conversion receiving channel; the down-conversion receiving channel outputs an intermediate frequency calibration signal after carrying out signal amplitude limiting processing, signal dynamic adjustment, spurious signal suppression, full temperature range gain compensation and phase consistency compensation. According to the invention, high channel isolation and switching of a plurality of working modes including a transceiving working mode, a calibration mode and the like are realized by adopting a switch assembly network. And meanwhile, the system also has the functions of sensitivity time control and manual gain control, and can realize large-dynamic-range echo signal processing and receiving under the condition of ensuring high isolation and multi-mode working conditions.

Description

technical field [0001] The invention relates to the field of radar, in particular to an X-band high-isolation radio frequency transceiver system and a channel consistency calibration method thereof. Background technique [0002] With the deepening of weapon research technology and the rapid development of manufacturing industry, the degree of informatization of modern equipment is getting higher and higher. Therefore, all countries in the world attach great importance to the development of phased array radar. The most important basic unit modules in phased array radar are T / R components and reference source modules, which have multi-channel reception, high isolation, multiple working modes, wide frequency hopping bandwidth, frequency Spurious suppression capabilities, etc.; under the condition of realizing multi-channel transceiver functions, it is important to ensure that the system has a high degree of isolation, and at the same time has a multi-work mode to ensure the fle...
