What type of ranging circuit is commonly used with radar to achieve extremely accurate range data?

A movable range marker is commonly used in radar systems to achieve highly accurate range data due to its capability to continuously adjust based on the received signal. In radar technology, the accuracy of range measurements is crucial, especially in applications such as air traffic control, weather monitoring, and military operations.

The movable range marker works by dynamically reflecting the position of the detected target relative to a reference point. As radar signals are sent out and reflected back from objects, the movable range is updated in real-time, allowing the system to provide precise distance measurements. This continuous tracking capability enhances the reliability of the radar system in determining targets' distances, making it essential for achieving high accuracy in ranging applications.

In contrast, static range markers or fixed range sensors do not offer the same level of dynamic adjustment, leading to potential limitations in accuracy. Digital range counters provide measurement data but may not incorporate real-time adjustments as effectively as a movable range marker in the context of radar systems. Thus, the movable range marker is particularly valuable in maintaining precision in range data for radar applications.
