Proposed Title
Simulation of Ground Penetrating Radar in 3-D using MATLAB.

Keyword

Based on the title proposed, the keyword here is Ground Penetrating Radar where the results of the images constructed will be in 3-D. The need for the images of the subsurface is crucial for the Matlab, where we will take note on the difference in terms of the volume, the permittivity, permeability, etc.

Objective

The objective of this project:

* Simulating the images constructed onto Matlab in 3-D.
* To understand what Ground Penetrating Radar is and how it works. * Building an even deeper understanding of the commands in Matlab.

Background

Ground Penetrating Radar (GPR) is a high resolution electromagnetic technique that is designed primarily to investigate the shallow subsurface of the earth, building materials, roads and bridges. GPR is a time-dependent geophysical technique that can provide a 3-D pseudo image of the subsurface, including the fourth dimension of colour and can also provide the accurate depth estimates for many common subsurface objects. GPR has many applications in a number of fields. In the Earth sciences it is used to study bedrock, soils, groundwater, and ice. Engineering applications include non-destructive testing (NDT) of structures and pavements, locating buried structures and utility lines, and studying soils and bedrock. In environmental remediation, GPR is used to define landfills, contaminant plumes, and other remediation sites, while in archaeology it is used for mapping archaeological features and cemeteries. GPR is used in law enforcement for locating clandestine graves and buried evidence. Military uses include detection of mines, unexploded ordinance, and tunnels.

This type of specialized radar works a lot like regular radar. The radar unit has a sending antenna which sends out pulses of sound, and a receiving antenna, which picks up those pulses when they bounce off objects underground. The returned pulses can be used to construct an image of what is underground, because they will vary depending on the depth and composition of buried objects.

Based on the image constructed, it can be saved and loaded onto Matlab and the information of the image will appear. Calculations and other related information will be coded into Matlab and produces the results that we all want at the end of the day.

There are several problems that I had encountered while doing this project. The main would be getting the Matlab software and choosing the most applicable Matlab software is because every time a new version comes out, there will be a slight difference in terms of codings and some may not understand the other. Hence, I have decided to precede using Matlab version 5.3 to be on the safer ground and that is what we mostly use these days, especially during our lab sessions as well. Another problem will be coding the Matlab. It is quite tedious to code because there are many codes involved and there are many aspects. Gathering the required information and formula that is to be coded onto Matlab is another difficult part because of the coding.

In terms of planning, I have decided to Google up the World Wide Web for the latest discovery using Ground Penetrating Radar using Matlab and the generation of the images in 3-D. Not many have actually done this before. For the enhancement part, I would like to connect Matlab with Google Earth and from there, we could browse around the earth to determine the information of a particular place that is wanted or required of the user.

In the first 3 weeks into this project, I was searching around for journals after journals to read what people from all walks of life have done for GPR. In the next few weeks, I was Googling up ways to code GPR into Matlab and I found it very amusing that it is not as simple as we all thought it would be. Apart from that, I was taking down notes on how to actually go about doing it and getting the whole idea...
