The atmospheric long-range propagation above the ground is of major importance for many ground systems as radars. The split-step wavelet method allows to compute efficiently this propagation, using a matrix-vector product for the free-space propagation. In this paper we propose a local method for the free-space propagation based on library of propa-gators. From numerical experiments, we show that this new method is cheaper in terms of memory cost whereas the matrix-vector product solution yields faster computation time.
