Q: 1. What is an OTH radar system?

Answer: An Over-The-Horizon (OTH) radar system is a type of radar that can detect targets over long distances by reflecting its signals off the ionosphere, a layer of the Earth's atmosphere.

Q: 2. How does an OTH radar system work?

Answer: An OTH radar system works by transmitting radio waves at a specific frequency towards the sky, where they are reflected off the ionosphere and redirected back to Earth. By analyzing the reflected signal, the radar system can detect and locate objects beyond the horizon.

Q: 3. What are the advantages of an OTH radar system?

Answer: OTH radar systems have the advantage of being able to detect targets over very long distances, typically up to several thousand kilometers. They can also operate independently of weather conditions and are difficult to jam.

Q: 4. What are the limitations of an OTH radar system?

Answer: The main limitations of OTH radar systems are that they have lower resolution and accuracy compared to other types of radar, and they can be affected by ionospheric disturbances, which can cause signal degradation and errors in the target location.

Q: 5. What are some applications of OTH radar systems?

Answer: OTH radar systems are used for various military and civilian applications, including surveillance of air and maritime traffic, border control, and early warning systems for missile attacks.
