[Meteor-Scatter] TV Carrier Radio Meteors

[Tony]

All:

Have a question regarding the characteristics of 
radio meteors. When monitoring TV video for meteor 
bursts, I've noticed that the heterodyne tones 
(SSB) vary by 200hz or more. I'm assuming this is 
due to the frequency variation from one TV 
transmitter to the next?

The other question has to do with signal arrival 
time. I've noticed that when several TV carriers 
come through with a good overdense burst, their 
signals arrive at different times by a few tenths 
/ second.

Is this due to the geometry of the ionized trail 
as it presents itself to the TV transmitters at 
different locations or is it due to the formation 
time of the trail?

Finally, Doppler shift tends to vary in hertz / 
second and was wondering what this means in terms 
of the vector or posistion of the incoming meteor 
relative to ones location.

Thanks,
