摘要
研制出了可用于飞行器滑翔着陆时使用的高精度激光测高仪。采用连续波脉冲测距的方法,实现高数据测量频率的要求,采用多数据加权平均的方法消除了测量数据的抖动以及杂光干扰带来的误差,提高了脉冲测距的精度。
A highly accurate laser altimeter is developed, which can be used on large pilotless aircraftfor landing. Continuous wave pulse range finder technique realizes the high frequency of measure data. In order to avoid the error brought by data shake and random light, weighted average replaces the single sampling data point; the precision of pulse finder is thus improved.
