Titel
Seafloor heightmap generation using 1D kernel reconstructions
Abstract
This paper extends a previously published seafloor reconstruction method from side-scan sonar data. The original method created 1D shape estimates for single side-scan measurements by comparing the measurement to an alphabet of pre-computed (ray-traced) sonar responses from kernels. The work described in this paper extends the method to obtain a 2.5D map of the seafloor from the 1D reconstructions through fusion of individual measurements. Additionally, the synthetic measurement generation has been refined to reflect more realistically the physical genesis of the sonar signal by allowing continuous wave (CW) or frequency modulated (FM) sonar pulses.
