Simulation of GPR environment

hello everyone

I am working now, in a project for simulating GPR environment using Microwave Studio.
Could any body help me in this by telling me from his/her experience about this issue:

1- is Microwave Studio is the most suitable for this ?
2- Is the FDTD method is the suitable method for the simulation?
3-How could i design the environment itself, and the GPR transmit and receive antennas?
4- what kind of data should i get from this simulation?


Thank you very much

I try to answer ypur questions
almost GPR project is create with Time Domain parameter.. it's different to make commonly antennas that use HFSS for frequency domain parameter..

1. I think XFDTD is easier than the other
2. FDTD is most suitable method
3. You must calculate couple radiation betwen TX and RX
4. -level (late time) ringing
-UWB bandwidth
-etc
