Which radar unit displays the corresponding radar information on a cathode ray tube (CRT)?

Which radar unit displays the corresponding radar information on a cathode ray tube (CRT)?

• A. Indicator
• B. Raster
• C. Plan Position Indicator (PPI)
• D. A-scan

Answer: (A)

Indicator is the component that presents radar data on a cathode ray tube. In radar systems, the indicator takes the information from the receiver and translates it into a visual display on the CRT so the operator can interpret echoes, ranges, and bearings. The Plan Position Indicator is a specific type of display that can be shown on a CRT, and an A-scan is another style of display (amplitude vs range), but the question points to the general unit responsible for displaying radar information on the CRT, which is the indicator. The term raster refers to the scanning method of the CRT, not the display unit itself.
