specific Embodiment approach 1
[0026] The specific embodiment one, UUV-based side-scan sonar image auxiliary interpretation method, the purpose of the present invention is achieved in this way:
[0027] Changes in speed, heading and roll affect the side scan sonar image. All other factors being equal, the faster the sonar passes over the target, the shorter the target will appear on the record. Steering the sideways direction of the inboard transducer will change the angle to scan a small location on the seafloor. In contrast, the outer transducer will sweep across a large sector.
[0028] However, we can only read the changes of speed information, heading information and roll information in digital form through software, and cannot observe their changes intuitively and as a whole. The present invention proposes a method for visualizing the speed information, course information and roll information, so as to realize the intuitive integration of the above-mentioned data interpretation and prepare for the n...
