An in-air sonar system is provided for determining location and velocity information of objects in an environment. The in-air sonar system includes at least two emitters configured to emit respective sound signals into the environment; at least two receivers configured to receive sound signals from the environment; and a processing unit configured to perform: obtaining, from the receivers, respective received sound signals comprising the emitted sound signal reflected from objects in the environment; calculating, from the respective received sound signals, respective velocity-dependent range maps; deriving, from the calculated velocity-dependent range maps and the spatial diversity of the receivers, a velocity-dependent range-direction map comprising range information as a function of a received direction; determining therefrom a location of the respective objects; and extracting, from the velocity-dependent range maps and the spatial diversity of the receivers, a velocity of the respective objects based on the determined location.

In-air sonar system and a method therefor

A sonar based sensor for localization of a target in air is described. The sensor comprises a wide or ultra-wide band emitter for emitting a wide or ultra-wide band signal, and a set of spatially randomly or irregularly positioned receivers for receiving the wide or ultra-wide band signal after reflection at the target. A corresponding processor and method for localizing also is disclosed.
