Sonar system for identifying foreign objects |
摘要 |
A sonar system is provided for identifying a foreign object includes a technique for providing a two dimensional array of pixels, each one of the pixels representing the intensity of a signal at a predetermined range position and a predetermined cross-range position from a reference position and quantizing the intensity of each one of the pixels into one of a plurality of levels. The technique further includes comparing a distribution of the levels of pixels over a range scan at a cross-range position with the distribution of levels of pixels over a range scan at a different cross-range position to identify the existence of a foreign object. With such an arrangement a sonar system is provided that can automatically detect the existence of a foreign object such as a mine.
