Abstract : In this work a sequential approach based on the Unscented Kalman Filter is applied to solve inverse problems in 1D hemodynamics, on a systemic network. For instance, the arterial stiffness is estimated by exploiting cross sectional area and mean speed observations in several locations of the arteries. The results are compared to those ones obtained by estimating the Pulse Wave Velocity and the Moens-Korteweg formula. In the last section, a perspective concerning the identification of the terminal models parameters and peripheral circulation (modeled by a Windkessel circuit) is presented.
