| 摘 要： | 针对地磁数据测量易受各种噪声和干扰影响,导致地磁匹配导航精度、概率和可靠性降低的问题,提出了一种采用小波强制降噪和多尺度融合的地磁匹配导航方法.该方法利用地磁数据高频部分易受噪声干扰影响而低频部分稳定性好、各尺度下的匹配结果具有相对独立性的特点,将含噪地磁基准图和实时图进行多尺度分解,在所选的多个尺度下经强制降噪后分别进行匹配,并融合各尺度下的匹配结果表决产生最终的导航结果.地磁匹配导航仿真实验结果表明该方法可有效提高导航的精度、概率和可靠性. |

| Abstract: | Matching accuracy,probability and reliability of geomagnetic navigation are reduced because geomagnetic measured data are easily affected by various noises and disturbances,and a method for geomagnetic matching navigation based on wavelet forced de-noising and multi-scale fusion is proposed to solve the problem in this paper.Because detail of each scale is easily affected by noises and disturbances and approach of each scale is steadier,and matching result of different scale is of relative independence,both... |
