Generate complex Doppler signal.
[FM,AM,IFLAW]=doppler(N,FS,F0,D,V) [FM,AM,IFLAW]=doppler(N,FS,F0,D,V,T0) [FM,AM,IFLAW]=doppler(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 frequency modulation.
Output amplitude modulation.
Output instantaneous frequency law.
Returns the frequency modulation (FM), the amplitude modulation (AM) and the instantaneous frequency law (IFLAW) of the signal received by a fixed observer from a moving target emitting a pure frequency f0.
