An acoustic radar is a device acting as the well known radars, with the difference that the transmitted and the received signals have frequencies in the acoustic region. A short acoustic pulse is transmitted in the atmosphere. While it is travelling in there, it is scattered from the atmospheric irregularities. Here, the irregularities don't mean a 'target' object, as in the usual electromagnetic or microwave radars. A change in the wind velocity, a turbulent layer, a temperature inversion e.t.c. cause scattering of the acoustic waves. A part of the scattered signal returns to the receiver, where it is collected and processed.
