  ABSTRACT: The aim of this work is to study the notion of the gradient observability on a subregionω of the evolution domainΩ for a class of semilinear hyperbolic systems. We show, under some hypothesis, that the gradient reconstruction is achieved following sectorial approach combined with fixed point techniques. The obtained results lead to an algorithm which can be implemented numerically.
