| 摘 要： | 提出了一种针对脉冲激光测距中非合作目标定位的新算法。该算法采用相关检测所得的峰值位置附近的若干采样点进行插值运算,并根据采样点距离峰值位置的远近赋予不同的权重,然后进行加权平均,从而得到非合作目标的准确位置。该算法充分利用了相关检测峰值位置附近的众多采样信息,避免了单个采样点对定位精度的影响,显著地提高了定位的精确度和稳定度。实验表明,该算法比直接用相关检测,测量精度约提高了1倍。

| Abstract: | This paper presents a new method for the detection of an un-cooperated target in pulsed laser ranging.Several nodes near the peak value of the correlation detection are adopted to interpolate,are assigned with different weight based on the distance to the peak value,and weighted average is carried out so that the exact position of the un-cooperated target will be gained finally.This method takes full advantage of the multiple messages near the peak-value of correlation detection so that the influence from t... |
