FACTORY SETTINGS OF A SIGNAL TRANSMITTER:

Signal speed = frequency x wavelength


WAVELENGTH CHANGE:


We have seen in the book many times that the part of (c + v) in the above Doppler Equation is the speed of the signal according to the reference system of the signal source.


From the above two equations, we can obtain following equation:

RELATIVE TO SIGNAL SOURCE:
SIGNAL SPEED SENT TO THE MOVING TARGET

Signal speed = Frequency of the transmitter x Changed wavelength



MEANING OF THE WAVELENGTH CHANGE:
λ1 = Speed of the signal sent to a moving target 


λ0 Speed of the signal sent to a stationary target
