Re: how can I import gpr data to voxler?

This is a too big question without details. I think Voxler can import some types of GPR data files directly, but not others. You probably have to look at the manuas of your Voxler version. If it doesn't import your data directly, you have to figure out a way to convert the data format to one of its...

Re: Profiler 400

You are using too much of the internal memory this is why. I think you can connect a new memory card and save data in there. Used to have one back in 2009 but not anymore.

Re: Old 300 Mhz GSSI Antenna question

You have to close the circuit when you want to use it as a monostatic. Send me a picture of the top of the antenna and I will tell you how to do it.

Re: Locating a man made tunnel

From the data above I’m not sure there is a tunnel anywhere. What could cause such anomalies? I have surveyed the wholel area and this was the only area that showed anomalies. The contrast has been turned down all the way and it still shows a strong signal. The only data that could be a void is the...

Re: Guess what's in the GPR profile

I believe the target below 40ns is a void. Nothing to do with above they surface targets. The 270mhz is an extremely well shielded antenna and even if it was unshielded the above the surface target would look quite differently.

Re: need advice

I dont see how archaeology needs that big depths. Typically archaeology needs 3-6m.

Re: ABOUT LOZA GPR ABILITY

I have never worked with Loza GPR so i cannot tell but you ned to check whether you can actually work with these radars. All Euroean countries and USA/Canada/China/Japan have strict emissions regulations. With very high power transmitter there is no compliance with these regulation and so it is not ...
