Y1 - 1993/12// N2 - We consider the problem of exact observability of the linear hyperbolic equation with time-varying coefficients under internal finite dimensional moving observations. Two types of scanning observations are considered and the existence of spatial curves and set-valued maps for sensors that ensure exact observability is established. The techniques involved are related to the construction of suitable skeletons for required observation curves and maps JF - Proceedings of the 32nd IEEE Conference on Decision and Control, 1993.
