Abstract: This paper presents an approach for design of multi-element ultra-short baseline (USBL) systems with the goal to improve the coordinate determination accuracy of the underwater objects. The object location estimation is performed on the base of the measurement of the distance to the object and the angular object position. It is supposed that the object is equipped with a transponder that receives the interrogation acoustical impulse and sends an acoustical impulse in reply. The idea of the design method is to increase of the number of receiving elements of the USBL antenna with a corresponding increase of the number of the receiving bases with the different spatial orientation. The arrangement of the array receiving elements is obtained by the rotations of the basic (three-element) receiving arrays around the longitudinal and lateral carrier axes (the case of the determination of the Cartesian coordinates of the object in the carrier coordinate system is considered!
). It is supposed that the control of the spatial orientation of the receiving USBL array is realized by means of measurement of its pitch and roll angles (in the carrier coordinate system). In the article the proposed method is applied for design of the nine-element USBL system. The special coordinate determination algorithm for the proposed USBL system is designed and tested. The simulation of the algorithm was realized with the assumption that the object can have an arbitrary location in the lower hemisphere and the receiving USBL antenna can have significant inclination. The coordinate determination accuracy of the proposed USBL system is evaluated.
Keywords: Ultra-short baseline (USBL) system, Underwater object, Transponder, Carrier coordinate system, Local coordinate system, Pitch and roll angles.
