Complex noisy doppler signal.
[Y,IFLAW]=dopnoise(N,FS,F0,D,V,T0,C)
number of points.
sampling frequency (in Hertz).
target frequency (in Hertz).
distance from the line to the observer (in meters).
target velocity (in m/s).
time center (default : N/2).
wave velocity (in m/s) (default : 340).
Output signal.
Model used as instantaneous frequency law.
dopnoise generates a complex noisy doppler signal, normalized so as to be of unit energy.
