The maximum range of radar systems can vary significantly depending on several factors, including radar type, operating frequency, power level, antenna size, and environmental conditions. In general, radar systems can detect targets at distances ranging from a few meters to several hundred kilometers. For example, short-range radar systems used in automotive applications typically have maximum ranges up to a few hundred meters, suitable for collision avoidance and adaptive cruise control. On the other hand, long-range surveillance radars used in military and air traffic control applications can detect aircraft and other targets at ranges exceeding several hundred kilometers, even up to thousands of kilometers in some cases. The feasible range of radar systems is crucial to their intended application, influencing operational effectiveness and situational awareness.
Ship radar systems, designed for maritime navigation and security, typically have maximum ranges that vary depending on the type and installation of the radar. Marine radars can detect other vessels, land masses and weather systems to ensure safe navigation on bodies of water. The maximum range of ship radar systems can be from a few nautical miles to over a hundred nautical miles, depending on factors such as antenna height, power output, and frequency band used. Short-range marine radars, often used for proximity navigation and collision avoidance, can have ranges of several nautical miles. Long-range marine radars, used to detect distant vessels and obstacles, can extend their coverage to more than a hundred nautical miles, providing early warning and improving the efficiency of maritime safety and navigation.
