Q

In a RADAR using digital video processing, a bright, wide ring appears at a fixed distance from the center of the display on all digital ranges. The transmitter is operating normally. What receiver circuit would you suspect is causing the problem?

🔍 Key Concepts

• Relationship between display artifacts and specific radar circuits • What the VRM (Variable Range Marker), EBL (Electronic Bearing Line), range ring generator, and video storage actually draw or affect on the screen • How a fault in a memory or storage path shows up visually on all ranges

💭 Think About

• Ask yourself: Which of these circuits would create a bright, wide ring that stays at the same distance from the center on every digital range scale? • Which items are normally thin reference lines (for measurement) versus something that handles the actual echo video across all ranges? • If the transmitter is normal, what part of the receiver/display chain could add an extra fixed‑range echo band everywhere?

✅ Before You Answer

• Identify which circuits normally generate measurement graphics only (lines, thin rings, cursors) instead of broad video patterns • Check which option is responsible for storing or shifting the processed video data before it’s displayed • Confirm that the suspected circuit’s failure could logically affect all digital ranges in the same way
