Ground Penetrating Radar• GPR is a non-destructive imaging method

that uses radar pulses to image the subsurface

• The radar pulses used are in the microwave band of the radio spectrum

How GPR Works?• GPR is similar to a metal detector• The GPR system sends out thousands of

RF frequency pulses into the ground • The frequencies that are reflected back

return to the antenna• Frequency analysis of the reflected RF

energy allows correlation of different material compositions in the subsurface

How Industrial Radiography Works• Similar to medical radiography, industrial

radiography uses an X-ray source to penetrate a sample with high-energy radiation onto a film or a digital detector

• This creates a 2D image of the different materials in the sample

Background Information• AMRDEC is the Weapons Integration & Development

Directorate of the US Army Aviation and Missile Research, Development, & Engineering Center

• They perform a variety of munitions and warhead test programs

• AMRDEC ‘s test facility is located in Huntsville, AL

Problem• Shrapnel X/Y location and mass is analyzed manually• Consumes up to 9600 man-hours of valuable time• Results in high operating costs

Approach• Implement an automated and portable system that will

scan the panels, and output an image mapping of the fragments• Use image processing program to analyze fragment

images, gather information on X/Y location, size, width, length, and perimeter

Industrial Radiography• Industrial Radiography is another non-destructive detection

method which utilizes X-rays and gamma rays to view materials
