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 x wavelength
