Which Supreme Court case is associated with the Doppler Principle?

The case associated with the Doppler Principle is indeed State vs Dantonio. This case is significant because it addressed the use of radar technology for speed detection, which operates based on the Doppler Effect. The Doppler Effect describes how the frequency of waves changes based on the motion of the source or observer. In the context of radar, it allows law enforcement to measure the speed of vehicles accurately by detecting the frequency shift of the radar waves that reflect off moving objects.

The ruling in this case helped solidify the legal acceptance of radar as a viable method for speed detection, emphasizing the importance of understanding the underlying principles of operation. Thus, the correct association with the Doppler Principle lies within the context and implications of State vs Dantonio.
