ABSTRACT:
A two dimensional velocity sensor mountable on an aircraft employs a CW radar which illuminates the ground with radar energy. Two transmitters which are alternately activated cause the speckle pattern to move as a whole in the opposite direction at the same speed. Two receivers mounted parallel to the heading axis of the aircraft sense the same power of the backscattered pattern except for a delay. By means of a time-shared processor and computer, this sensed delay provides heading velocity as well as cross-heading velocity.
