| Popis: | Signal processing and display (GPR devices Ground Penetrating Radar) are the two main sections in this discussion. The main part of the software for the reflected signal processing consists of: plotting that serves to represent the beat waveform (computing, Fast Fourier Transform) which acts to obtain the frequency beat used to determine the depth of the underground pipes. Process Windowing to eliminate noise and turn the results into a logarithmic form of FF T computation to make it more evident is the difference between the soil with pipe and the last the process of converting the units to obtain information the depth and position of pipelines in units of meters. All the information and the process will be displayed on the tablet (display). Besides that, there are signal processing modules Graphical User Inteface (GUI) which consists of some of the menus and sub menus to facilitate users in operating display 3n-GPR. On testing integrated successfully acquired signals beat waveform computing the FF T and the resulting frequency varies when the antenna transmitter and receiver the line of sight distance is personalized way. Process Windowing successfully carried out using function of Hamming Window. Testing with emulation method successfully done with varying frequency signal input from function generator corresponding to the price to a depth of 0-2 meters which is the position of the underground pipes in General. The GUI has been created successfully function consisting of a variety of menus, submenus, and widgets that facilitate users in operating display. Communication between signal processing with display (Tablet) through VNC (Virtual Network Computing). |
