When it comes to sound propagation, the Doppler Shift is the shift in pitch of a source as it travels. The frequency seems to grow as the source approaches the listener and decreases as the origin fades away from the ear. When the source is going toward the listener, its velocity is positive; when it is traveling away ...

Webon target Doppler, and ranges from 0 dB at 2.5 knots to 12 dB at 10 knots Doppler shift. The FM waveform performs better for Doppler searches less than 2.5 knots, up to about 18 dB at zero-Doppler. The CW reverberation ridge will narrow as the pulse length or center frequency increases. 3 Bistatic Target Strength (b) The Doppler effect or Doppler shift (or simply Doppler, when in context) is the apparent change in frequency of a wave in relation to an observer moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842. A common example of Doppler shift is the change of pitch heard when a vehicle sounding …
