Abstract
The invention is related to a method for controlling a device for the ultrasound detection of objects in air, said device comprising a plurality of transducers, used as transmitters and adapted to operate in a phased grid, and at least one transducer, used as a receiver, which are mounted on a support, wherein, prior to at least one detection operation, a calibration step is carried out in order to ascertain a structural phase shift of the transmitter with respect to the reference transmitter, which is then memorized so as to later be able to correct the theoretical phase shifts of the transmitters from the structural phase shift value when shots are ordered later.
