What phenomenon can occur when a target maneuvers, causing random reflectivity due to radar pulses bouncing off different areas of the target?

Scintillation refers to the phenomenon where the radar returns fluctuate due to changes in the characteristics of the target as it maneuvers. This can occur when radar pulses bounce off various areas of the target, leading to a random variation in the reflectivity of the target's surface. The changes in angle and surface properties caused by the target’s movement can create a rapidly changing signal that can confuse radar systems, making it challenging to track the target accurately. Understanding scintillation is crucial for radar operators as it impacts the effectiveness of target detection and tracking capabilities.
