(angular) resolution
What plays a large part in quality of range resolution? Right Ans - Pulse
Width
What is the ability of radar to separate objects at the SAME range but at
DIFFERENT bearing or elevation angles? Right Ans - Bearing (angular)
resolution
What is the ability of the radar to determine range, bearing, and height of an
object? Right Ans - Radar accuracy
