What is the difference between active and passive radar systems in fire control?

In the context of fire control systems, active and passive radar systems serve distinct roles based on how they detect targets. The correct answer highlights a fundamental difference: active radar systems actively emit signals, such as radio waves or microwaves, and then analyze the echoes that bounce back from objects, allowing them to determine the location and characteristics of those targets. This proactive approach enables real-time tracking and engagement of targets.

On the other hand, passive radar systems do not emit their own signals. Instead, they listen for signals that are already being emitted by targets or other sources. This allows passive systems to identify and track objects without revealing their own location, making them valuable in stealth operations and in environments where being undetected is crucial.

Understanding this differentiation is vital for fire controlman, as it influences not only detection and tracking strategies but also the overall effectiveness and tactical applications of various radar systems in military operations.
