Abstract
The invention relates to a synthetic sonar antenna and more particularly to the self-calibration of such an antenna. It consists in minimizing the number of sensors of the reception antenna by fixing the reduced pitch between the sensors, imposed by the precision of the self-calibration, solely at the two ends of the antenna. According to a variant, the reduced pitch is fixed at just one end of the antenna. It makes it possible to increase the precision of the self-calibration with a smaller number of sensors than in the prior art.
Claims3
A synthetic sonar antenna, the geometry of the reception antenna being optimized in such a way as to minimize the number of sensors by fixing the pitch imposed by the precision of the self-calibration at at least one end of the reception antenna.
