In which year did RADAR systems that provide range information during tracking debut?

Radar systems that provide range information during tracking significantly advanced around the year 2011. This period marked a notable development in radar technology where systems were enhanced to not only detect targets but also accurately measure their distance, or range, relative to the radar unit. This capability is crucial for effective tracking, especially in dynamic environments where the relative positions of objects change rapidly.

The introduction of these advanced radar systems allowed for improved situational awareness and target discrimination, significantly benefiting various applications such as air traffic control, military operations, and weather monitoring. Enhanced range information aids operators in making vital decisions based on precise data regarding the distance of detected objects, thereby improving overall efficiency and safety in operations. This technological evolution illustrates the continual progression of radar capabilities and the growing complexity of tracking systems in the early 21st century.
