Abstract

The invention provides a phase stabilization device of a receiving end of a multichannel broadband microwave optical transmission link. The phase stabilization device comprises a phase measurement pilot link, a delay measurement pilot link, a controller and a plurality of optical transmission links, each optical transmission link comprises a transmitting part and a receiving part connected throughan optical fiber, output ends of the phase measurement pilot link and the delay measurement pilot link correspondingly provide a first optical signal and a second optical signal to the receiving part, and the receiving part transmits the first optical signal and the second optical signal to the transmitting part through an optical fiber; the transmitting part transmits the first optical signal and the second optical signal together with an input optical signal of the transmitting part to the receiving part through an optical fiber, and the receiving part outputs the input optical signal and correspondingly transmits the first optical signal and the second optical signal to the receiving ends of the phase measurement pilot link and the delay measurement pilot link so as to measure phase differences and time differences of the optical transmission links, thereby adjusting the phases of the optical signals in the optical transmission links in a phase stabilization manner.

Description

technical field [0001] The invention belongs to the field of microwave optical transmission, in particular to a multi-channel broadband microwave optical transmission link receiving end phase stabilization device. Background technique [0002] Due to the advantages of broadband, low loss, flexible distribution, anti-interference and low weight, microwave optical transmission technology is very suitable for the transmission and distribution of radio frequency signals, especially broadband high frequency signals. Remote control, phased array sub-array, etc. have broad application prospects. In these applications, ensuring the phase stability of a single-channel microwave optical transmission link and the phase consistency between multiple channels is one of the key technologies to realize system functions. However, the optical transmission medium optical fiber is affected by the external environment (temperature, vibration, etc.), which will cause the equivalent length of the...
