We all very good know dopper for light

what about intensity of signal ( LUX power )

I have kindly ask anyone can help me prepare simulation ( solar system model and intensity of signal problem )

sensor ----> V1 ----------R distance ----------------Source -------> V2


if V1 <V2
sensor will register RED shift and step by step lower intensity of signal ( level of signal will go down )


if V1 =V2 ???? astronomers think that we have 20 km/s



sensor 1 -----------150 000 000 km -----SUN  -----------150 000 000 km -----sensor 2  -------> 20 km/s


sensor 1 will register biger brightness
