Abstract
A radar speed measurement device (10) comprising a display (12) for displaying a target speed, a radar emitter (14) for emitting radar waves toward a target, a radar receiver (16) for receiving radar waves reflected from the target, an analog to digital converter (18) for producing digital signals associated with the radar waves, and a signal processor (20) for determining the target speed by analyzing the digital signals. The device (10) can also calculate statistics associated with the target and further comprises a statistical processor (22) for calculating the statistics. The device (10) can operate in either of two modes. A speed mode is preferably used to determine the target speed, when the target is a race car or any other object. A baseball statistics mode is preferably used to determine the target speed, when the target is a baseball thrown by a pitcher.
