卫星平台随机振动对星间激光链路通信质量产生增大误码率等不良影响。为了有效地补偿随机振动，提高通信质量，本文设计并搭建了一套用于模拟卫星平台振动与补偿的实验系统。该系统通过面阵CCD 探测光束偏转角度，采用压电陶瓷致动的快速偏转镜模拟、补偿卫星平台的随机振动。针对随机振动补偿实验的特殊性，文中定义了补偿效率因子ηR 以描述补偿效果。实验结果表明，该系统对卫星平台振动中的低频分量具有一定的补偿能力，当CCD 采样频率高于振动频率三倍以上时，该系统对低频随机振动的补偿效果显著。

The negative effect of satellite vibration on the intersatellite laser communication was presented, including the increase of bit error rate. To solve the problem of random vibration compensating, a testbed was designed and assembled,which detects the deflection angle caused by vibration with a high frame frequency area charge coupled device. The testbed simulates and compensates vibration with fast steering mirrors actuated by piezoelectric actuators. As there is difference between sine wave vibration and random vibration, the compensation efficiency factor ηR is defined to evaluate effectiveness of random vibration compensation. The experiment result shows when the sample rate of CCD is three times of that of vibration frequency, the compensation efficiency is remarkable, and the compensation of the testbed is effective.
