Abstract:

The general objective is to continue development of the remote sensing sonar concept for tracking surface and volume motion of the upper ocean, with or without the aid of detectable scattering layers. A linking algorithm was developed to track the motion of the surface and scattering layers. Optical flow methods were applied to sonar images as an alternative means of tracking volume motion to the coherent remote sensing algorithm reported earlier. The optical flow methods proved to be inappropriate. A number of display formats were explored, and the moving wireframe was found to be most effective. The algorithm and display were extended to the three-dimensional case. JHD
