    Hi Bulgarians.
    Mikebg, there need not be Murphy, but in that area for me are the water courses, here called "live water/vein water" but I wish at the beginning of the first treasure chest!
    Christo. My congratulations, first of all for the program, top notch!
    As many as strange that give ADC: 8 bits - is a great visual results.
    But in your post # 15 is already a signature "Decoder Card 16bits-DS", as if the sound card (Rate 44100Hz).
    I'm not so wise, so I ask what *. SGY open the file and where can I find "Prizm 2.5"?
    It would be nice if you can move at least partly my images with maps derived from measurements at this gradiometer platform.
    Once again, success!
    Chris.

      Are these the same generators ?

        Unknowing, the black box in the right is not generator, it is receiver

        Enjoy!

            Unknowing, you don't know how to rotate image.

                Yes, I agree! Unknowing, you are Knowing!

                    A GPR with a 44100Hz Sampling Rate ?
                    Something is wrong here.
                    I would like to know what kind of ADC is used here,
                    because the Soundcard wont cut it in the Nanoseconds Range of a GPR.

                      have developed two software for this project, one works in sound card, in other com port with adc 8 bit.

                        Two software is OK, but why delete it ?

                          Hi Anto22.
                          Give a little more technical data and some ideii.
                          Maybe it is an interesting approach can be applied anywhere else?
                          You have an interesting cut noise. Good filters in DS card?
                          It may be developmental ideas.
                          Congratulations.
                          Best regards Chris.

                            Sampling the GPR rx (received) Signal with a Sound Card or through the Com Port (without extra Logic like a FPGA) is just plain impossible.
                            Your Screenshots look like a 1GHz ADC is running (around 1ns for a Sample).
                            A Soundcard would need 23us... useless for GPR.

                              Hello.
                              very good question.
                              I dont have of 1ghz adc. I have developed a sample&hold scheme that contains radar itself, it slows down time very fast processes and displays them slowly so they can be visualized by slow adc.
                              This is actually a radar.

                                Can anybody explain why 8nS pulse in white ellipse is triangular ?

                                Thanks!
