ABSTRACT:
Control circuits are provided in a perspective radar display to modify the vertical sweep wave form voltage function on the display cathode ray tube to correspond to the sweep function which would be provided if the observer and radar antenna were at a different position from the actual position. This different position may constitute a different altitude or a different range or a combination of both. If the perspective display is used in an aircraft flying at, for example, 100 feet, the pilot can modify the display to provide a perspective radar image as would appear if the aircraft were at an altitude, for example, of 500 feet or 5,000 feet thereby rendering more easily distinguishable distant objects close to the horizon. Alternatively or in combination with a simulated or augmented altitude, the pilot can effectively modify the display to effectively provide a display which would occur at an increased range from targets so that close in targets are rendered visible. The same principles are applicable to boats and ships.
