New open GPR project, asking for collaboration

[williamblandy]

Hi!


Goals:
-designing and prototyping a working GPR
-all result should be free and available to all
-cost effectiveness
-interchangeable antennas for different frequencies

My initial block scheme:




Feel free to correct and expand

Some topic for start:

TX:
-how do we couple the antenna to the transmitter with minimal loss?
-which antenna arrangement needs no balun transformer?
-afaik dsrd is the way to go. is there another possible way?
-dsrd diode type?
-pulse shaping?
-do we need bandpass filters?

RX:
-do we need bandpass filters?
-gain compensation is in analog, or in digital?

Sampling:
-delay line type? DS1023 or so?
-buffer amplifier between t&h and adc? details?

Data output:
-is there a common file format for GPR data?
-any free visualisation tool?
-is opengpr sw project usable?

Steps:
-determine resoultion, worst case timings
-establish a detailed block scheme, antenna type and configuration
-TX module
-RX module
-sampling
-data processing

Please join in!

Hi alprinceeg,

I hope the trouble in Egypt will come to an end very soon.
By the way, you should write "Warm greetings from Egypt" not "Worm greetings". A worm is a small soft-bodied animal that lives in the soil.
