SONAR-IMAGE-SIMULATION METHOD FOR IMAGE PREDICTION OF IMAGING SONAR AND APPARATUS USING THE SONAR-IMAGE-SIMULATION METHOD

摘要

Disclosed herein are a sonar-image-simulation method for image prediction of an imaging sonar and an apparatus using the sonar-image-simulation method. The sonar-image-simulation method includes the models of ultrasound beams of the imaging sonar, a target object, and a background on which the target object is placed, which have been described as multiple straight lines, multiple polygons, and an infinite plane, respectively. The method also includes calculating intersection points of the multiple straight lines with the multiple polygons or the infinite plane to derive image data needed to construct simulated sonar images. Based on the computed image data, the method can construct the simulated sonar images of any arbitrary-shaped object.
