摘要
介绍了空间滤波、频域滤波和时域滤波等方法对白天测距成功率的影响,阐述了空间滤波技术的设计方案及在卫星激光测距系统中的实施过程。实验结果表明,空间滤波技术能够有效地抑制白天天光背景噪声,使白天激光测距成为可能。
The effects of different filtering techniques on the daytime observations were presented, including the spatial filtering, the frequency-domain filtering and the time-domain filtering techniques. The design scheme of spatial filtering and its implementation in the SLR system were described in great details. The experimental results indicate that this spatial filtering technique can suppress the daytime background noise effectively and enable the daytime observation of satellite laser ranging.
