TWO-COORDINATE SOUNDER

FIELD: navigation systems.SUBSTANCE: invention relates to hydroacoustic navigation of moving underwater objects, to which, along with the coordinates of the place and the elements of motion, both the depth coordinates are also included, namely, the depth of their immersion and the distance to the bottom with the subsequent provision of the display of these spatial coordinates and their dynamics on the indicators of information and control systems. Said result is achieved by the fact that the output of the phase-measuring device, included in the radiation path, is sensitive to the immersion depth of the object and the associated value of the active and passive components of the radiation resistance of electroacoustic transducers, connected to an indicator or other device that consumes electronic information represented in terms of the depth of the dive. Comparative analysis of the proposed device with analogues and prototype shows that this device, firstly, it allows to solve a new problem of operatively determining two coordinates in depth (the distance of the submerged mobile device from the surface and the bottom or the depth of immersion and the depth under the keel), secondly, it contains a well-known phase metering device that performs the new function of a depth-sensitive element without moving the latter into the outboard space, and, finally, it promptly provides information to consumers in depth and under the keel in electronic form.EFFECT: combining devices for measuring two coordinates of the depth of a moving underwater object in the aquatic environment, namely, the distance from the surface and the bottom, in one device; substantial constructive simplification of the devices used to solve similar problems, due to the integration of two functions in one device; in addition, the measurement result presented in electronic (digital) form can be directly perceived and used for its intended purpose in real time by various users of information on the position of the underwater object relative to the bottom and surface.1 cl, 1 dwg Изобретение относится к гидроакустической навигации подвижных подводных объектов, к которой, наряду с координатами места и элементами движения, относят также и обе координаты по глубине, а именно глубину их погружения и расстояние до дна с последующим обеспечением отображения этих пространственных координат и их динамики на индикаторах информационно-управляющих систем.
