PROBLEM TO BE SOLVED: To provide an underwater navigating body system for searching enabling remote control by providing a high-precision solid (three-dimensional) image, and allowing an operator to quickly give instruction about processing to a projected object. SOLUTION: This underwater navigating body system for searching comprises a search navigating body 3 and a search commanding device 1 for ships. The search navigating body simultaneously obtains two-dimensional image data and sonar data by using a synthetic aperture technique with underwater sound so as to measure the distance from the object, conducts a spectrum estimating processing and a contrast optimization processing by using a synthetic aperture signal processing technique so as to produce sonar image data, and then produces three-dimensional image data by composing the sonar image data to the two-dimensional image data. The search commanding device 1 for ships receives the three-dimensional image data through an automotive relay 2, and indicates a three-dimensional image reproduced on the basis of the three- dimensional image data on a panoramic screen. |
