Abstract :
We consider the problem of reconstructing superimposed temperature and wind flow fields from acoustic measurements. A new technique based solely on acoustic waves propagation is presented. In contrast to the usual straight ray assumption, a bent ray model is considered in order to achieve higher accuracy. Under this assumption, we propose an iterative reconstruction algorithm that allows to entirely recover the considered fields. It alternates between estimating the fields of interest and the corresponding acoustic ray trajectories. Simulation results confirm the effectiveness and fast convergence of our scheme
