What are you going to be using for calculations? If you are planning on
using DSP cards, then you don't need to go through PCI. You coud transfer
data directly from your A/D card to a DSP card using for example FPDP
interface.

There is a number of companies who do similar things for radar and sonar.
Look at the products by Pentek, ICS, Gage, etc...

BTW, I think this discussion drifted away from the FPGA topic, so it
probably doesn't belong here...
