🔍 Key Concepts

• RACON (radar beacon) returns are coded pulses (Morse) transmitted in response to your radar pulse • How a radial line of returns will look on a PPI when the beacon replies along one specific bearing • Difference between a normal point target echo and a beacon that smears or stretches along the range scale

💭 Think About

• On a PPI, if a buoy simply reflected your radar pulse like any other object, what would its echo look like? Now, how would that change if the buoy is transmitting multiple coded pulses back along the same bearing? • Would a racon’s coded reply be confined to one small spot on the screen, or would it occupy multiple range cells along the same bearing line? Look at which option shows that behavior. • Compare which illustration suggests an identifying Morse code pattern along a constant bearing, rather than just a stronger or larger single echo.

✅ Before You Answer

• Verify which option shows returns that are all on one bearing (same angle) but spread over a range of distances. • Check which picture looks different from an ordinary target echo (single small pip) and instead looks like a series/segment of pips that could form a Morse character. • Make sure the pattern originates along the correct radial from your ship’s position (screen center) and not as a ring or unrelated cluster.
