Subject: hammer seismic interpretation

Hi, I have  a question about interpretation of 
seismic data for the group. I have built a hammer
seismic system which incorporates a memory scope. I
can hammer the ground any number of times and sum the
returned signal. This gives vastly increased
sensitivity and immunity to noise. can anyone suggest
sources of information on how to measure the depth to
bedrock with this type of device?

I have used the sound card on a pc and piezo disks to
detect and trigger the data collection.

Best Regards
