Summary: | The invention provides a rapid calculation method of an arc synthetic aperture ground-based radar coordinate projection. The rapid calculation method comprises the following steps that a coordinate value (r, theta) sequence and terrain three-dimensional point cloud data of a radar irradiation scene under a polar coordinate system taking a radar as a center is obtained; projection polar coordinates(r, theta) of the terrain point cloud under the coordinate system is calculated; and a certain number of projection polar coordinate values of terrain point clouds are selected, and for the projection polar coordinate value of each terrain point cloud, if r-r is less than delta r and theta-theta is less than delta theta, the point cloud is considered to be the terrain point cloud covered by a measurement grid with a certain coordinate value (r, theta) of an irradiation scene under a radar polar coordinate system. According to the rapid calculation method of the arc synthetic aperture ground-based radar coordinate pro |
