Transformation of displacement and orientation correction data
Read, Robert R.
MetadataShow full item record
The simulation of an underwater vehicle track has been used to develop reference distributions for displacement and orientation corrections to the test range sensor arrays. These distributions show unusual behavior. Of particular concern are the scatter plots of the magnitude of displacement and orientation rotation angle, which exhibit a "hairpin" shape. The mechanisms producing this shape are interpreted and data transformations are developed that produce scatter plots of more regular form. In addition, some plotting methods are applied to provide some visual information about the joint distribution of the transformed data.
