Over-the-horizon radar (OTH), sometimes called beyond the horizon radar (BTH), is a type of radar system with the ability to detect targets at very long ranges, typically hundreds to thousands of kilometres, beyond the radar horizon, which is the distance limit for ordinary radar.
Raytheon’s Relocatable Over-the-Horizon Radar (ROTHR) is a long range, land based, wide area surveillance system that reliably detects aircraft and ships, within designated surveillance zones off the U.S. coastline. Designed to operate without violating other nations’ sovereignty, ROTHR tracks each target’s speed, course, and position
Two US Navy high-frequency (HF) over-the-horizon (OTH) radars known as ROTHR (Relocatable Over-the-Horizon Radar) are operated at Corpus Christi TX and Chesapeake VA, with coverage of the Caribbean Sea and portions of the Atlantic Ocean and the Gulf of Mexico.
Raytheon’s Next Generation Over-the-Horizon Radar uses a 2D array to increase radar sensitivity and generate two dimensional target picture. Raytheon has more than 30 years of experience developing, manufacturing, sustaining and upgrading Over-the-Horizon radars, like the Relocatable Over-the-Horizon Radar pictured here.
Relocatable Over-the-Horizon Radar (ROTHR), also known as AN/TPS-71, is an OTH Radar used by the United States Navy that uses bistatic ionospheric backscattering for wide area surveillance.

This webinar featured a briefing from Mr. Larry Nelson, Director Relocatable Over-The-Horizon-Radar \(ROTHR\) at the Forces Surveillance Support Center \(FSSC\). His briefing included an overview of the ROTHR mission, specific wind turbine radar interfere\ nce issues associated with the radars, and potential mitigation options.
Raytheon Technologies business Raytheon Intelligence & Space (RI&S) has secured a five-year $146m contract to support the US Navy’s counter narco-terrorism operations. The contract will see RI&S continue operating and maintaining the US Government’s relocatable over-the-horizon radar (ROTHR) system.
Raytheon Technologies Corp. RTX has secured a contract to support relocatable over-the-horizon radar (ROTHR). The award has been provided by the Naval Supply Systems Command Fleet Logistics...
The AN/TPS-71 Relocatable Over-The-Horizon Radar (ROTHR) is a tactical ionospheric backscatter radar system. It is similar in concept to the U.S. Air Force AN/FPS-118 Over-The-Horizon-Backscatter (OTH-B) strategic early warning radar system.
