doppler receiver
1Doppler radar — Doppler effect A Doppler radar is a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection …
2Doppler effect — Change of wavelength caused by motion of the source. An animation illustrating how the Doppler effect causes a car engine or siren to soun …
3Doppler effect — The change in frequency with which energy reaches a receiver when the receiver and the energy source are in motion relative to each other. Since the Doppler frequency shift is proportional to radial velocity, a radar system that measures such a… …
4Doppler shift — In airborne Doppler radar, a transmitter which, by means of a directional antenna, radiates energy toward the ground. This results in a situation in which both the transmitter and the receiver are moving relative to the ground; consequently the… …
5Doppler ranging — A continuous wave trajectory measuring system that uses the Doppler effect to measure velocities between the transmitter, vehicle, transponder, and several receiving stations. Doppler effect in moving receiver …
6Doppler effect — /ˈdɒplər əfɛkt / (say dopluhr uhfekt) noun the apparent change in frequency and wavelength of a train of sound or light waves if the distance between the source and the receiver is changing. {See doppler} …
7Doppler effect — apparent change in the frequency of sound or light waves due to a change in the distance between the source of the waves and the receiver …
8Bistatic Doppler shift — is a specific example of the Doppler effect that is observed by a radar or sonar system with a separated transmitter and receiver. The Doppler shift is due to the component of motion of the object in the direction of the transmitter, plus the… …
9Acoustic Doppler Current Profiler — Head of an ADCP with the four transducers ADCP view ahead, mo …
10Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of …
