The present invention provides a radar effective detection area extraction method based on a remote sensing image. A radar interference area and an effective detection area are extracted, a false object caused by ground clutter is eliminated, offshore location distribution information of a radar target is visually and truly reflected, and a real basis is provided for traffic situation evaluation. The method is different from other common interference area extraction methods or effective detection area extraction methods, a remote sensing image is adopted to assist in distinguishing the type of an area of a radar detection range, an interference area (an area generated by clutters such as land and islands) and an effective detection area are accurately extracted, the accuracy degrees of detection and entry are improved, and a reliable basis is provided for radar target display of a VTS system. |
