how far can radar detect
The detection range of radar systems can vary greatly depending on several factors, including the type of radar, its frequency, power, the size of the target, and environmental conditions. Here are some general guidelines for different types of radar:
-
Air Traffic Control Radar:
- Long-range radar systems used for air traffic control can detect targets up to 200-300 miles (322-483 kilometers) away.
- Terminal radar systems, which are used for airport approaches, typically have a range of 30-50 miles (48-80 kilometers).
-
Military Radar:
- Early warning radar systems can detect incoming threats at ranges over 1,000 miles (1,609 kilometers).
- Fighter aircraft radar can detect targets at ranges from 20-100 miles (32-161 kilometers), depending on the system.
-
Marine Radar:
- Commercial marine radar systems typically have ranges from 2-20 miles (3-32 kilometers), depending on the size of the antenna and power output.
- Larger ships may have radar systems with ranges up to 40 miles (64 kilometers).
-
Weather Radar:
- Doppler weather radar systems can detect precipitation up to 100-150 miles (161-241 kilometers) away.
- Phased array radar systems used for weather can have even longer ranges, up to 300 miles (483 kilometers).
-
Automotive Radar:
- Radar systems used in vehicles for adaptive cruise control and collision avoidance typically have a range of 100-300 meters (328-984 feet).
- Space-Based Radar:
- Radar systems on satellites can detect targets on the Earth’s surface from hundreds to thousands of miles (kilometers) away, depending on the mission and technology.
It’s important to note that these ranges are approximate and can be affected by factors such as atmospheric conditions, terrain, the size and reflectivity of the target, and the resolution of the radar system.
