Abstract

A procedure for locating the places of falling of fragments of a launch vehicle (LV) by recording the infrasonic signals is presented. The algorithms for generating pipes of real trajectories of falling fragments, for calculating signal parameters (sound propagation in the atmosphere), and for comparing the theoretical and experimental parameters are examined. The ways atmospheric parameters influence calculation accuracy is estimated.
