METHOD OF DISPLAYING HYDROLOCATION INFORMATION Russian patent published in 2020 - IPC G01S15/00 

FIELD: physics.

SUBSTANCE: invention relates to the field of hydroacoustics. Method for displaying hydrolocation information comprises emitting a probing signal, receiving an echo signal by a static fan M of the directivity characteristics (DC), discretization of input information and for each of M directions K times mapping of L elements of distance on indicator in all directions, probing signal is emitted by a semicylindrical hydroacoustic antenna which generates one wide DC and one vertical DC, reception of echo-signals is carried out by a cylindrical antenna, which forms a horizontal and vertical view of space along the direction characteristics with the formation of a fan of vertical directivity characteristics of width Q° and S horizontal characteristics with width Y° horizontally in each vertical tier, where lower vertical tier S of horizontal characteristics is identically repeated on all N vertical tiers, according to each direction characteristic, consecutive digitized time readings of echo signals are received on L distance elements, stored, determining a signal with maximum amplitude, normalizing all readings relative to the signal with maximum amplitude and after the processing is sequentially displayed on the indicator along the distance, along all horizontal characteristics of the orientation of each vertical level, starting from the lower one, wherein with each subsequent time processing cycle K of the next element on the distance L, reducing the display area size on the display screen, for which information of each distance element is displayed on a smaller area of the screen, than a volumetric representation of all information on the distance, along the horizontal and vertical lines is formed.

EFFECT: invention can be used in design and development of active sonar systems for obtaining more complete information on spatial position of detected objects in one radiation-reception cycle.
