Abstract
A radar device for measuring the surface velocity of water moving in a horizontal plane in which the radar device is positioned above or below the horizontal plane. The radar device includes a tilt sensor, or accelerometer, to measure the angle of tilt of the radar device with respect to a target point located at a distance from the radar device. The accelerometer generates a signal representing the tilt angle. A processor in the radar device calculates the cosine correction factor that is applied to the measured velocity of the target point. This results in an automatically corrected measured velocity being displayed on the radar device.
