About this tool

Calculates the maximum visible distance of a radar signal based on various geographical parameters. Users input values such as the elevation of the observer, the height of the target, and the radius of curvature of the Earth. The tool utilizes established principles of spherical geometry to determine how far straight-line visibility is extended beyond simple line-of-sight estimates. It provides an accurate prediction of the horizon distance when accounting for atmospheric refraction effects commonly used in surveying and navigation science. Individuals studying geodesy, amateur radio enthusiasts, or field surveyors use this calculator to plan optimal detection ranges. Understanding the true radar horizon helps them assess the effective operational limits of equipment before deployment.
