You have another ship overtaking you close aboard to starboard. You have 3 radar targets bearing 090° relative at ranges of .5 mile, 1 mile, and 1.5 miles. In this case, the unwanted echoes are called __________.

Question

You have another ship overtaking you close aboard to starboard. You have 3 radar targets bearing 090&deg; relative at ranges of .5 mile, 1 mile, and 1.5 miles. In this case, the unwanted echoes are called __________.

Accepted Answer

Option A: multiple echoes. Multiple echoes occur on a PPI scope when radar pulses bounce repeatedly between own vessel's superstructure and a very close, highly reflective target. This creates equidistant false targets lined up along the same relative bearing, identical to the true echo's range intervals.
