摘要

研究了一种用于2.67 Gbps光DPSK通信的闭环控制Mach-Zehnder干涉仪在模拟多普勒效应和大气闪烁效应下的性能。测试期间应用的频率转换率超过了LEO到地面或GEO、飞机到GEO和LEO到LEO卫星激光通信链路的预期频率转换率。应用闪烁时间序列来源于最近在近地轨道上收集的数据，这些数据是在NFIRE卫星和位于西班牙特内里费岛的欧洲航天局天文台地面站之间进行通信的。给出了实际激光通信系统预期的高信噪比和低信噪比条件下的接收功率水平范围的结果。

Wavelength tracking interferometer for DPSK lasercom links

The performance of a closed loop controlled Mach-Zehnder interferometer for optical DPSK communications at 2.67 Gbps in the presence of simulated Doppler and atmospheric scintillation effects is presented. The applied frequency slew rate during testing exceeded those expected for LEO to ground or GEO, aircraft to GEO and LEO to LEO satellite lasercom links. The applied scintillation time series were derived from data collected during recent LEO to ground communications between the NFIRE satellite and the ground station at the European Space Agency observatory in Tenerife, Spain. Results are presented for a range of received power levels representing high and low SNR conditions anticipated for real lasercom systems.
