Comparison between DPCA Algorithm and Inertial Navigation on the Ixsea Shadows SAS

In this paper, we present some results obtained with the Shadows system, the new synthetic aperture sonar, by IXSEA. First sections are a slight presentation where we expose the performances and specifications of Shadows. We present the results obtained on the lateral sonar by using first the algorithm of DPCA, second the simulation of DPCA parameters by using the navigation data. Hence we present some results obtained by comparing the two methods. The data were recorded by the Shadows system in La Ciotat Bay during summer 2006.
