Subject: Signal To Noise Ratio of a Seismic Sensor

Hello PSN:
Can someone out there run down a list of
best ways to increase the signal to noise
ratio of a seismic sensor ?
Things like:
1. in a mass spring system use a larger mass
2. use a phased array
3. use low resistance's in the circuitry
4. use a narrow bandwidth
5. use a high Q
6. shield everything against anything not a seismic signal.
7. a high signal to noise ratio is not possible for the average amateur due to cost
it might take a bunch of amatures to pool their monies and talents to
create a decent seismic sensor, possibly such a thing is only possible
at a university where both money and talent exists.
Does any know of a system out there with the
highest signal to noise ratio...if so can we see it ?
More then likely it is in military hands
and is secret ?
In all the discussions I have seen in this group
none seem to concentrate on signal to noise ratio.
Sincerely;
gmvoeth
