What is the purpose of range marks produced by the range marks generator?

The purpose of range marks produced by the range marks generator is to indicate distance on the CRT (Cathode Ray Tube) display. These range marks serve as reference points which help radar operators understand how far away an object is from the radar system. By demarcating specific distances on the screen, operators can visually assess the range of detected objects in relation to set markings. This functionality is essential for accurate determination of object distance, which plays a critical role in various radar applications, such as navigation, tracking, and surveillance.

Other options touch on different aspects of radar technology but do not accurately describe the function of range marks: determining the direction of static objects relates more to angular positioning rather than distance, amplifying radar signals pertains to increasing signal strength for better detection, and filtering out noise involves improving signal clarity which is unrelated to marking distances.
