In this paper, we talk about the collection aperture's normalized arrival-of-angle fluctuationspectrum in Satellite-ground laser communication.
根据星地激光通信的实际状况，对接收孔径的归一化到达角起伏频谱进行了讨论。

For uniform time sampling, the level of frequency fluctuation will greatly influence the results of spectrum analysis.
采用等时隙采样方法，频率随机波动的大小则会严重影响谱分析的结果。

Results show that the frequency spectrum characteristics of arc diffluence is accordance to jet fluctuation. Arc diffluence in the new gun is confined obviously.
