Radar measurement via characterization
A computer-implemented radar simulation method is provided for directing a radar beam to a target. The method includes receiving target position from the target; computing target coordinates in a select frame of reference; inserting random noise error into the target coordinates as accuracy degradation to represent at least one radar performance characteristic; providing the accuracy degradation into the frame of reference; and directing the radar beam by the accuracy degradation towards the target.
