Doppler
This term is a technical adjective derived from the name of Christian Doppler. It is almost exclusively used in scientific, medical, and law enforcement contexts to describe instruments or phenomena that utilize frequency shifts to measure velocity or blood flow.
In practical usage, it frequently appears as a modifier for specific technologies, such as radar or ultrasound. Because it describes a specific physical principle, it does not have a casual or metaphorical equivalent in standard English conversation.
