INTRODUCTION
“Landmines and unexploded ordnance (UXO) are a legacy of war”
What are Landmines?
Landmines are container ofexplosives that
are triggered by contact with a person or
vehicles.
What are UXO?
UXO are bombs or fired rocket launchers whose
fuses did not detonate.
There are two types of Landmines
Anti-tank(AT)
AT are designed to destroy
tanks and armored vehicles.
Anti-personnel(AP)
Is an explosive device made
to injure or kill a person.
Impulse Generator
The pulse generator delivered by SATIS Co. produces 0.8 ns monocycle pulses.
Covers a wide frequency band from 500MHz till 2GHz .
It was found experimentally that the 0.8ns monocycle satisfies penetration and resolution requirements.
Antenna System
The GPR System’s performance strongly depends on the antenna system.
The antenna system consist of transmitter and receiver.
The transmit antenna should:
Radiate ultra-wide band (UWB).
Radiate electro magnetic energy.
Produce an optimal footprint.
Type of the ground.
The Receiver antenna should:
sufficient sensitivity in order to receive very weak fields.
Receive the field in a local point.
Be elevated at least 10cm above the ground surface.
