They operate in the HF … WebMar 10, 2024 · OTH radars use two main techniques to detect long-range targets: 1. Shortwave Propagation: In shortwave propagation, radio signals in the HF range (3 to 30 MHz) are transmitted at a certain angle from an antenna or an array of antennas. These signals get refracted towards the ground by the ionosphere, thus allowing them to return …
