多普勒声呐安装误差补偿方法研究

A study of compensation of Doppler sonar's intallation error

多普勒声呐利用多普勒频移原理,测量多普勒声呐相对海底的速度,随着测量精度的提高和宽带多普勒声呐的出现,已经应用于多种载体的导航。由于多普勒声呐在换能器安装和在载体上安装时,不可避免出现误差,而安装误差对于测量载体的绝对速度有较大的影响。本文主要研究换能器安装误差、安装角度误差和安装位置的补偿方法,对于提高多普勒声呐的测量精度具有较大的意义。

Doppler sonar measure carrier＇s velocity relative to the bottom according to Doppler theory. With the improve of measuring precision and the appearance of brand band Doppler sonar,Doppler sonar is used in navigation of multiple carriers. As the transducers were installed and Doppler sonar was installed in carrier, error is inevitable. The error affect the velocity measuring greatly. The paper study the method of compensation of the installation of transducers, the angles and location of Doppler sonar, it＇s meaningful to improving the measuring precision of Doppler sonar.
