Sensor simulation of underwater terrain matching based on sea chart

Abstract

Accurate underwater topographic map and terrain matching sensor is the foundation of underwater terrain matching navigation. The precise terrain database was founded by extracting the data of electronic chart using program firstly, and then interpolating the data. The underwater terrain model was established based on the precise terrain database. Besides, the functional simulation of sensors, such as acoustic altimeter and multi-beam sonar, was discussed in use of the intersecting line detection function of ray array in Vega. By comparing the simulation experiment data and interpolating data, it can be seen that simulating terrain matching sensor by using the intersecting line detection function of Vega is available. © 2011 Springer-Verlag Berlin Heidelberg.
