  • Moving target speed and direction determining radar system
    Patent number: 4038658
    Abstract: A radar is mounted on an airplane with a pair of antennas affixed to the airplane and directed to one side thereof for providing a relatively narrow radar beam squinted approximately 20.degree. ahead of a line transverse to the direction of motion and approximately 20.degree. behind the line, respectively. The radar is constructed to alternately energize the antennas and a visual display system provides individually identifiable visual indications of targets interrupting the beams. The amount a target moves on the visual display between the interruptions of the forward and rearward directed beams provides a direct indication of the direction and speed of the target.
