WebA model for predicting the performance of an over-the-horizon high frequency (HF) radar is described. The program can also be used for management of an existing radar or for HF broadcasting assessment. When the radar parameters, such as power, antenna, and frequency are given the program predicts the signal-to-noise, ground clutter-to-noise, Web…the first successful demonstration of high-frequency over-the-horizon (HF OTH) radar, whose propagating waves are refracted by the Earth’s ionosphere. The detection of ships, aircraft, and ballistic missiles was thereby extended out to about 3,200 km (2,000 miles), approximately 10 times the range of microwave radars, which are limited to the…
Web18 de jun. de 2024 · The sky-wave over-the-horizon radar (OTHR) uses ionospheric reflection or refraction to realize the propagation of radio waves. It mainly uses shortwave frequency bands, usually 3–30 MHz, and its range can break through the limitations of the curvature of the earth beyond the line-of-sight [1], and the over-the-horizon radar is … WebTarget detection and tracking with a high frequency ground wave over-the-horizon radar Abstract: This paper describes the principle of an high frequency (HF) ground wave over-the-horizon radar (GW-OTHR), presents an overview of the structure of GW-OTHR and gives some experimental results.
