FIELD: sonar.SUBSTANCE: present invention relates to sonar and is intended for use in illumination stations near environment at measurement of parameters of detected object. Method of measuring depth of immersion, including radiation two successive probing signals from moving carrier, receiving echo signals of hydroacoustic antenna mounted on a support, measurement of distance Daccording to first probing signal, measurement of distance Din second probing signal, measurement of own carrier speed V, consists in that is formed on a hydroacoustic antenna receiving static fan of directivity characteristics in horizontal plane, receiving echo signals with static fan of directivity characteristics in horizontal plane, measuring radial speed of approach to object V, measurement of direction of natural movement of the carrier, direction of arrival of echo signal is measured between direction of carrier and direction of arrival of echo signal Q°, determining speed of approach to object taking into account difference between direction of movement and position of object in horizontal plane V= V/cos Q°, define cosine angle of position of object relative to direction of motion in vertical plane cosU°=V/V, and depth of immersion of object is determined by formulaEFFECT: technical result is improved accuracy of measuring depth of immersion of object using sonar.1 cl, 1 dwg |
