对高重频激光测距中多脉冲异常测距现象进行了分析和研究，采用地靶测量脉冲时间间隔、主波时刻校正和屏幕处理等技术方法，得出多脉冲测量数据的处理方法。将该方法应用于实测数据的处理，结果表明：按多脉冲测量数据进行处理后，有效数据量至少增加10%，均方根值基本一致，有利于测量回波信号较少但存在多脉冲现象时的中高轨卫星测量数据处理。

The data processing method for multi-pulse measured data in high frequency laser ranging is analyzed and researched, and a useful method is got by measuring pulse interval time using ground target ranging, adjusting transmitting epoch, screen processing and etc. Applied to process ranging data from 1.2 m telescope high frequency laser ranging system, it indicates efficient data increasing 10% at least, and root mean square hardly changing. This is significant to middle and high orbit satellites laser ranging data process where the echo signal is a few but there is muti-pulse measured data phenomenon.
