Scintillation (radar)

{{Other uses|Scintillation (disambiguation)}}

Scintillation is a fluctuation in the amplitude of a target on a radar display. It is closely related to target glint, or wander, an apparent displacement of the target from its mean position. This effect can be caused by a shift of the effective reflection point on the target, but has other causes as well. The fluctuations can be slow (scan-to-scan) or rapid (pulse-to-pulse).{{cite journal |last1=Dunn |first1=J.H. |last2=Howard |first2=D.D. |title=RADAR Target Amplitude, Angle, and Doppler Scintillation from Analysis of the Echo Signal Propagating in Space |journal=IEEE Transactions on Microwave Theory and Techniques |date=September 1968 |volume=16 |issue=9 |pages=715–728 |doi=10.1109/TMTT.1968.1126776|bibcode=1968ITMTT..16..715D }}

It appears especially at seaside level.

Scintillation and glint are actually two manifestations of the same phenomenon and are most properly linked to one another in target modeling.{{cite book
