This document presents information on a ground penetrating radar (GPR) system for landmine detection. It discusses the global problem of landmines, provides an overview of the GPR hardware and system capabilities, including A-scan and B-scan visualization. It notes that the system collects 127 returns per second with 12-bit accuracy over a range of 4-32 ns. The document outlines testing and evaluation of the system by the U.S. Army, and lists advantages of GPR such as accurate measurements, ability to locate small targets, and operation without biological limits. It concludes that the developed GPR system is efficient for detecting small, shallow buried objects.

3. Landmines: Global Humanitarian Problem
84 countries have a problem with landmines
58 of these countries reported mine
casualties in 2004
5. Introduction
land mines and unexploded
ordance(uxo)
What are land mines?
Land mines are containers are
triggered by
contact with vehicles.
What are uxo?
Uxo are bombs or fired rockets
Fuses do not detonate.
11. A-scan is a method for
detecting the presence and
absence of surrogate mine
in clay soil.
B scan or Radar gram
is used to visualize
the target of
surrogate mine.

13. OVERVIEW OF THE SYSTEM
The system collects 127
returns, or surroundings,
per second, each
composed of 512 samples
with 12 bit accuracy. The
sounding range may vary
from 4 ns to 32ns
14. Testing and evaluation
U.S Army performs
objective blind and scored
testing at their testing
facilities, which include
carefully constructed mine
lines.
15. ADVANTAGES
GPR has accurate measurements.
GPR locates even small targets.
It has been well founded by the defense.
GPR operates by detecting the dielectric soils which allows
it to locate even no metallic mines.
Biological sensors can only operate for limited periods, but
in GPR has no such limits.
GPR has been tested in different environmental conditions.
16. CONCLUSION
This is an efficient one in which video impulse
ground penetrating radar system for detection for
small and shallow buried objects has been
developed.
