( thx for SATRON for this im only translated ..)
very high error rates in emfad device.
because; EMFAD devices only one (receiver) has been working ... If you examine the inside just VLF- (VERY LOW FREQUENCY) 3-30 kHz ( changing for models.. ) among employees using radio transmitters of signals broadcast on the same frequency of a simple receiver ... I see briefly explain to benefit the core logic; Electronic connoisseurs already know,
AM (amplitude modulation) expenses by mansion land after leaving the transducer due to the wavelength is short ... so it can be delivered to undergo more distortion and more distant from the face of obstacles ... but,
noise due to the modulation form factors cause a high signal transfer
emfad engineer who is familiar with this logic from a remote location broadcasting radio broadcasts (VLF and ELF) was used as the transmitter signal to the frequency devices
This publication, while the radio broadcast from the transmitter supply, these devices are sent at very high watts of power over long distances
the world in certain ways toward Earth by reflecting the lithosphere circulating around the world in this way, while the frequencies are affected by weather conditions and very high voltage lines in
Emfad, we do not know a radio broadcast of the uncertain results of our exploration and reflection on where we do not know in a way known in the power transfer us
I think it might be called semi-active device ....
GP is the difference in these results (if using FMCW) ... is built publication with a real-time transmitter source frequency is clear ... modulation and sent back to the reflected signal quality is the frequency modulation is FMCW as a continuous wave is real ... FM (frequency modulation) also there is a structure free from the noise ... especially a used modulation shape is a triangle wave becomes excellent results that sweep effects just considered ... breakages resulting spectrum difference occurred outside the actual frequency frequency of the analyzer in values between us soil layers played will give us real-time soil structure it becomes possible to understand the exact ...
FMCW radar was invented time closer, it was there before the normal pulse and used the old pulse radar system particularly in the ship.
he gave the ship target detection on the use of pulse radar systems with FMCW radar images of the matter to compare the very high resolution of the FMCW radar will see.
For example, at 900 meters above sea view, large and small has a lot of ships and boats, and these are only able to see the radar pulses that are large, the same clearly see this in the slightest, including FMCW radar from large distance.
cause of FMCW radar signal is constantly formed.
