METHOD AND APPARATUS FOR TERRAIN CORRELATION

摘要

A method for testing radar system performance is disclosed which utilizes radar daata test points in a radar data file (302). The method includes interpolating (312) GPS data (306) from a flight test to provide a GPS data point for every radar data test point, generating body coordinate values (314) for every point in a corresponding digital elevation map (DEM) file (284) using the interpolated GPS data, and applying a bounding function around at least a portion of the body coordinate values generated from the DEM file at a given time. The method also includes determining which body coordinate value (324) generated from the DEM file is closest a current GPS data point for the given time and comparing the determined body coordinate value to the radar data test points at the given time.
