Radio waves travel at the speed of light, roughly 1,000 feet per microsecond , so if the radar set has a good high-speed clock it can measure the distance of the airplane very accurately.
Read moreWhy is there a max range for radar?
Maximum Range: Radar Max Range is determined, ideally speaking, on the properties of the antenna only. A signal at a certain frequency is transmitted, reflected, then hopefully, detected. Due to the three-dimensional propagation of radar waves, frequency hold the highest weight in determining range .
Read moreWhat is the minimum range of radar?
The pulse width (H) determines the minimum range at which targets can be detected. This minimum range is approximately ½ the length of the wave burst . In the case of the 4.5µS pulse, the minimum range would be 675 meters (2,215 feet).
Read moreWhat is the maximum range of radar?
Therefore, the maximum range of Radar for given specifications is 158KM .
Read moreHow far can radar detect?
This permits target detection at distances from about 500 to 2,000 nautical miles (900 to 3,700 km) . Thus, an HF over-the-horizon (OTH) radar can detect aircraft at distances up to 10 times that of a ground-based microwave air-surveillance radar, whose range is limited by the curvature of the Earth.
