An Altitude-Error Display for Height-Finder Radar

Abstract

Strong ducting conditions occur over many ocean areas. These conditions affect height-finder radars (such as the SPS-48) in giving accurate target positions. Most height-finder radars calculate altitude based on a standard atmosphere. When ducting conditions are present, large errors can occur between the calculated and the true target height, depending on the transmitter height and the target range. In many cases, these errors are greater than 50 percent. A height-finder radar altitude-error display has been developed to show the amount of error present. The display looks like an ordinary ray-trace display, except the color of the rays are dependent on the height difference, as compared to and standard atmosphere for the same elevation angle and range. Keywords include: Height-finder radars, Target height, Ray-trace display, Altitude-error display, HP9000-500 series computer, IREPS.
