INTRODUCTION
“Landmines and unexploded ordnance (UXO) are legacy of

war”
 What are Landmines?

Landmines are container of explosives 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
1. Anti-tank(AT)
AT are designed to destroy tanks and

armored vehicles.
2. Anti-personnel(AP)
Is an explosive device made to injure or

kill a person.
HARDWARE DESCRIPTION
IMPULSE GENERATOR
• The pulse generator delivered by SATIS Coproduces

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 requirement.
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
Pulse Extender
 Pulse extender will amplify the ground reflection.
A/D Converter
 TXr RXr High speed sampler A/D converter.

 Center frequency and Bandwidth.
 PROCESSOR
 A/D converter Processor.
 Processes the signal.
 Presence or absence of surrogate mine.
 Mine detecting signal Visual display.
 Visual Display
 Range of targets.
 Exact position.
OVERVIEW OF THESYSTEM
• A series of measurements has been taken using a set of targets

buried in the various types of soil.
• An FR-127-MSCB (Imp) developed by CSIRO.
• System collects 127 echoes or surroundings per second.
• Each composed of 512 samples with 12bit accuracy.
• Sounding range vary from 4ns to 32ns.
• GPR uses bi static bow-tie antenna which transmits wideband, ultra

short duration pulses.
 A-Scan
 Presence or absence of surrogate mine .
 The Electromagnetic field is scattered.
 The graph is Amplitude Vs Time
 Graph is used for visual inspection
 B- Scan
 Visualize the target of surrogate mine.
 B-san calculates distance from soil to the mine.
 Shows target at 55 cm and 100 cm.
 Graph helps to calculate the distance from ground to mine

DEPLOYMENT PLATFORM
Testing and Evaluation
• US Army performs test at their testing facilities ,

which include carefully constructed mine lines.
• Testing and Evaluation environment, landmines
are live.
• Dirt and gravel lanes are maintained.
PRO’S &CONS
• GPR has accurate • The sensor such as GPR is

• GPR locates even small • GPR is more power-hungry.

• It has been well founded by rates as high as metal

• Biological sensors can only • GPR can be very effective or
operate for limited periods, ineffective, depending on

• GPR has been tested

conditions
Conclusion
• Impulse GPR system is using for detecting anti-tank and

anti-personal mines.
• Currently, very little technology is used in real-world
demining activities.
• Through iterative design, build test cycles, and blind and
scored testing at Army mine lanes.
