signal (Doppler shift) gives the means to calculate the meteors velocity and path direction related to the
radio observers location.
Interpreting the meteroids direction to the radio observer location is attained by the frequency change.
The increase in freqeuncy shift establishes the meteoride is moving towards the receivers anttena and lower
frequency shift moving away. This is known as Doppler effect. The frequency shift is caused by motion
that changes the number of wavelengths between the reflector meteoroid plasma and the radio receiver.
Using and transforming the following formula, with the transmitter frequency used, the conversion processes can establish the velocity of the captured radio meteor signature traces. = c (f02 ? f2) / (f02 + f2)
- v = (veloicity), c (speed of light (3x10 8 m/s),
fo (Radio observers static frequency), f (frequency change). Meteors velocity range from 14 kilometers/
second (31,000 miles per hour) to 45 kilometers per second (100,000 miles per hour.
As well as dynamic visuel radio meteor images that can be attained a wealth of analytical data can be
extracted. Below 3D and long trace Leonid radio meteor capture during increase activity at 05:03am.
Leonid meteor peak was between 3:00am and 6:00am when the Earth track and orientation plowed
through Comet 55P/Temple-Tuttle debri.
Difference in radio signal strengths and frequency drifts in time show their representation in the meteor radio
captures.
