ABSTRACT:
The process, the imaging system and the probe are intended to obtain images by way of waves emitted by an antenna after reflection of these waves at the level of a target-like assembly illuminated by the waves emitted and on the basis of which the images are extracted, said antenna consisting of at least one array of wave emitter/receiver tranducers. The process carries out a series of emissions of the same type by providing the transducers with identical excitation signals which are staggered in time so as to generate an essentially plane wave at each emission. The delays between transducers is determined so that the equiphase surfaces obtained are in line or in a plane according to whether the antenna includes an array of transducers.
