Glint is caused by which condition?

Glint happens when the radar echo’s apparent center shifts because the vessel and its surroundings are moving in the waves. In a seaway, the ship tilts and pivots (pitch, roll, yaw), so different facets of the hull and nearby reflecting surfaces line up with the radar beam at different times. That changing geometry makes the centroid of the echo move on the display and can produce bright, flickering spots. It’s not due to a transmitter fault or atmospheric propagation. While a rapid change in aspect can cause shifts, the key driver is the target’s motion in the seaway altering which facet is reflecting energy back toward the radar.
