A cheap GPR prototype has been developed by the workgroup of COST Action TU1208.
Python_GUI_4_Sliders_2.py - software in Python, provides GUI to control the radar
Calc_DAC_with_Predistortion.py - software in Python, imported in "Python_GUI_4_Sliders_2.py" to precalculate DAC values
gpr_icon.ico, GPR_logo.gif - images used in the GUI
Mbed_Python_Control_LPC1768_2.bin - firmware to load on LPC microcontroller
Mbed_Python_Control_LPC1768_2_main.txt - same firmware to read the code in the text format
TU1208_Guide to building a GPR radar for educational use _FINAL.pdf - Developer's Guide, see page 2 to reference this project
Datasheets.zip - an archive with datasheets of different radar components
PCBs.zip - an archive with printed circuit boards designs (masks in .png format)
that there is no tutorial for designing antennas so far. If you make ones, publish your results and send me a link - this could be a valuable contribution to this project and beneficial for other researchers.
