Would somebody please help me parse this.

I am reading a book by P.R.P. Hoole: Smart Antennas and Signal
Processing. In Chapter 2.9.3 Inverse Doppler effect in the near-field
region I have found the following statement:

"The Doppler frequency shift depends on the distance between the
source and the observation point. Hence the radial and tangential
electric field (magnetic field) components of the electromagnetic
radiation exhibit different Doppler frequency shifts. The Doppler
frequency shift of the radial eelctric field component is given by:
(nasty formula #1). The Doppler frequency shift of the tangential
component electric field component is given by: (nasty formula #2)."
and later "..it is seen that when the scatterer is approaching the
transmitter the Doppler frequency should increase. But from Fig 2.12
it is also seen that very close to the transceiver the Doppler
frequency shift is actually decreasing. This is the so-called inverse
Doppler effect. ... It is seen that the maximum Doppler frequency
shift of the radial field component varies erratically with velocity.
A similar inverse Doppler effect is exhibited by the tangential
electric field component as well. In imaging moving objects in the
near-field region, this inverse Doppler effect has to be taken into
consideration in the imaging routines.."

It is a cover-up fallacy imposed by Einstein-Lorentz scam supporters.

I've never heard of the inverse Doppler effect. But the far field is the
region where the distance from the antenna is very large compared to the
size of the antenna, and the near field is where it isn't. So I'd suppose
it would be something like this.

and the slanty line indicates a line of radiation. If the receiver is
moving to the left, he intercepts the radiation on the oblique instead of
antiparallel. Non-relativistically there is no Doppler shift if the
signal is moving perpendicularly to the receiver.

Its OK thow ,,,fords first invention was a pogo stick ,,all the farmers
were to hop...
befor he had one good idia he had 1000 stuipid ones. like the upside
down gum tray and the reusable tire plugs.

Not really. Some hits are just titles of articles not readily available,
and the others discuss materials with novel optical properties. None of
them are very instructive or would help the original poster.

components of a wave guide. [Old Man]
