| 摘要： | A modified Hough transform to detect targets on sonar B-scan produced from data collected by a passive acoustic sensor array is presented. Assuming mat the target maintains a constant course and speed during the observation period, the target trace on the passive sonar B-scan can be shown as an arctangent function defined by the following target track parameters speed, course, range at the closest point of approach CPA, and CPA time. Detection of the target traces on the sonar B-scan can then be formulated as detection of the arctangent curves using the modified Hough transform. The track parameters of the target can be estimated and used to identify different targets. |
