CA 2652566

The invention relates to a sonar system with a synthetic antenna, comprising: a sonar provided with transmission means and reception means and located on a mobile carrier, the reception means comprising a composite physical antenna having N transducers; an inertial central station which is arranged on the carrier and can measure instantaneous information relating to the position and orientation of the carrier; a common clock supplying a temporal signal enabling the synchronisation of both the inertial central station and the sonar; a means for determining the instantaneous speed of the carrier, the speed determined feeding the inertial central station in order to correct the drift thereof; and micronavigation means enabling an image of the marine life to be obtained by the formation of paths of the synthetic antenna from K operation returns of the sonar, taking into account the fact that the physical antenna movement during the displacement of the carrier is known in its entirety from the information measured by the inertial central station.

Système sonar à antenne synthétique comportant : un sonar muni de moyens d'émission et de moyens de réception, lesdits moyens de réception comportant une antenne physique composite ayant N transducteurs, ledit sonar étant situé sur un porteur apte à être déplacé; une centrale inertielle disposée sur ledit porteur apte à mesurer des informations instantanées de position et d'orientation dudit porteur; une horloge commune délivrant un signal temporel permettant la synchronisation à la fois de la centrale inertielle et du sonar; un moyen de détermination de la vitesse instantanée dudit porteur, la vitesse déterminée alimentant ladite centrale inertielle pour corriger la dérive de cette dernière; et, des moyens de micronavigation permettant d'obtenir une image du fond marin par formation des voies de ladite antenne synthétique à partir de K récurrences de fonctionnement du sonar en considérant que le mouvement de l'antenne physique au cours du déplacement du porteur est entièrement connu d'après les informations mesurées par ladite centrale inertielle.
