Conclusion

Landmines are considered one of the most horrifying, unethical tactics used in modern wars.

◦ Large minefields is planted with anti-personnel explosives, usually to give a temporary strategic advantage, and get left after wars, ending thousands of innocent civilian lives, and preventing the social and economical development to reach the affected zones.

Egypt considered one of the most affected countries with landmines, with nearly 20% of the total landmines in the world.

◦ "The northwest coast has great development potential; the area is one of the greatest promises for Egypt. But the mines deny access to a landmass of approximately 22 percent of the national territory," El-Shazly* said.

Used in the initial detection phase

Either sharply accurate or precise

Advantages◦ Simplest◦ Cheapest◦ Widely used

Disadvantages◦ Dangerous

◦ Another significant issue concerns the safety of the deminer. For every 5000 mines removed, one deminer is killed.

Had been mainly used in Afghanistan

Less risk on the deminer himself

Generally, the most efficient solution

Special vehicles, that can withstand the explosions

Combine detection & removal in one operation

Sometimes, used as an extra layer of security after another method

Research had been made to make use of the following, for landmine detection as well:

◦ Honey bees

◦ Mammals

◦ Plants

◦ bacteria

Therefore, the Egyptian Government and agencies providing assistance must allow for substantial resources to be devoted to finding better solutions to the mine and UXO clearance problem.

EMI Sensors

GPR Sensors

Seismic Sensors

14

Page 15: Sensors

EMI Stands for Electromagnetic Induction

Time-varying magnetic field

Detect most metals

Unacceptable false alarm rate

15

Page 16: Sensors

GPR stands for Ground Penetration Radar

Uses electromagnetic waves

Waves reflected from buried objects

Antennas transmit and receive the waves

Very clean response

16

Page 17: Sensors

Probes the surface with seismic waves

Excite mechanical response of buried objects

Distinction between landmines and other objects is clear from formed images

Very resistant to most types of clutter
