Source Position Observability In A Multipath Channel
Maria João Rendas, José M. F. Moura · 2005
This paper studies the impact of the mul- tipath structure of the underwater acoustic channel on the observability of the position of a distant source. Us- ing a recently proposed definition of ambiguity function we study the observability of source position in multipath channels using a propagation model of moderate complex- ity. To assess the importance of multipath modeling on the observability structure, we compare the ambiguity sur- faces to those obtained with propagation models that con- sider only the spatial structure (wavefront curvature and orientation) of the received wavefield. /
