Radar bullet

INTRODUCTION

Radar bullet is a relatively new discovery that was invented in mid $$ in

the %&. 't is used for detecting land mines. And this discovery finds a very

important prospect as about "($ countries singed a treaty in favor of banning

anti-personal mines. This treaty was signed during the second wee of )arch

"$$$ in *ttawa Canada.

Anti -personal mines claims seventy new victims every day. This weapon

is particularly cruel on children whose bodies being smaller and closer to the

blast. Are more liely to sustain serious in!ury. The severe disabilities and

psychological trauma that follow the blast mean these children will have to be

looed after for many year.

A child in!ured at the age of ten will need about #+ artificial limbs during

their life time. The cost is ,(000 a huge sum to pay in countries where people

earn as little as "0 a month between "$/$ and "$$0 the red cross fitted over

/0000 amputees with artificial limbs. And the landmines problem is still

growing. Therefore considering these factors the discovery of radar bullet is

really a big boost to our world as we launches into the #"1 t century.

Technologies are used for landmine detection are2

)etal detectors--- capable of finding even low-metal content mines in

minerali3ed soils.

4uclear magnetic resonance fast neutron activation and thermal

neutron activation.

Thermal imaging and electro-optical sensors--- detect evidence of

buried ob!ects.

5iological sensors such as dogs pigs bees and birds.

Chemical sensors such as thermal fluorescence--- detect airborne and

waterborne presence of e6plosive vapors.

'n this discussion we will concentrate on Radar This ultra wide band radar

provides centimeter resolution to locate even small targets. There are two

distinct types of Radar time-domain and fre7uency domain. Time domain

or impulse Radar transmits discrete pulses of nanosecond duration and

digiti3es the returns at 893 sample rates. :re7uency domain radar systems

transmit single fre7uencies either uni7uely as a series of fre7uency steps or

as a chirp. The amplitude and phase of the return signal is measured. The

resulting data is converted to the time domain. Radar operates by detecting

the dielectric contrasts in the soils which allows it to locate even non

metallic mines.

Radar bullet is a special type of bullet the main use of radar bullet is to find

landmines without setting foot into the ground .This consists of firing a

special bullet into ground from a helicopter which could pinpoint buried

landmines

The bullet emits a radar pulse as it grinds to halt .This pulse stries the mine

and its image gets available on the computer in the helicopter offering a

safe and efficient way of finding land mines 'n this discussion we deal with

buried anti-tan =AT> and anti-personnel =A?> landmines which re7uire

close approach or contact to activate. AT mines range from about "+ to (+

cm in si3e. They are typically buried up to ;0cm deep but they can also be

deployed on the surface of a road to bloc a column of machinery. A? mines

range from about + to "+cm in si3e. AT mines which are designed to impede

the progress of destroy vehicles and A? mines which are designed to ill

and maim people.

?R'4C'?<E&

Radar is radio detection and ranging. Radar maes use of radio waves to

detect and locate ob!ects. Radar is a sensor its purpose is to provide estimates

of certain characteristic if its surroundings most commonly the presence and

motion of aircrafts ships or vehicles.

Radar operates by transmitting electromagnetic energy into the

surroundings and detecting energy reflected by ob!ects. 'f a narrow beam of

this energy is transmitted by the directive antenna the direction from which

reflections come and hence the bearing of the ob!ect may be estimated. The

distance to the reflecting ob!ect is estimated by measuring the period between

the transmission of the radar pulse and reception of the echo. 'n radar bullet

principle the change of medium by the waves must be taen into

consideration.
