Firsty the gunpowder used in landmine was able to absorb moisture and water from air which consequently losses it's explosive ability. The unique feature generator is small trailing oscillations, which are below 2. These non-metals challenge the capacity of current metal detectors. Signal and Array Processing, 1, pp. It displays the exact position of landmine. I would also like to thank Lecturer Mr. These ways of detection are dangerous because they are done very close to the mine.
As the name suggests detection is done using Radar Bullets and hence can be done further away from the mine carefully. Bullets fire from helicopter emits radar pulses as it grinds to the halt these radar pulses reflects from landed mines due to that reflection landmines can be estimated approximately.
This is the method in which special type of radar bullet are use to find landmines without setting foot into the ground offering safe and efficient way of landmine detection.
There are some methods for detection of land mines, such Metal detector method, Biological method and mechanical method. These methods are dangerous and risk is involved to life of solider. Radar bullet is a relatively new discovery used Annually people injured and losing their specially for detection of land mines. And this was lives only because of landmines accidents . It is very important invention because around 85 estimated that there millions active buried countries having problem with landmine, and landmines that means one landmines for every 52 approximately 20, peoples injured and kill people.
Landmines are found along roads, in fields every year by land mines accidents. In this and forest, near wells and river bank so it causes discussion, main concentrate is Radar this ultra serious economical problem for the countries. Radar bullet the mainly mines that are removed, one person is kill and two used to find land mines without setting foot into the persons are injured because main methods used for ground. This consists of firing a special bullet into demining means removal of mines are mines ground from a helicopter which could pinpoint detection using metal detectors and biological buried land mines even though landmines which method of detection by specially trained mine remains active for over 50 years after its detection dog but these methods are typically slow, implementation.
Radar bullet internally consists of expensive and dangerous but new technology of microwave emitter. This microwave emitter emits detection of landmines using radar bullets is the electromagnetic waves whose wavelength The effective alternatives this technique is worthy for bullet emits a radar pulse as it grinds to halt.
This human being. The word ''mines'' is derived from the Latin word mina which means vein of ore and was originally Radar bullet specially designed and use for applied to the dug the hole in the ground.
The term detection of landmines without setting foot into was then borrowed by military engineers having ground. Internally it consists of microwave emitter.
The mines were firstly it used to waves whose wavelength are conventionally destroy target located above but they were later measured in small number of centimeter called filled with explosive like gunpowder or black microwave. Microwave band having very large powder. By the 14th century gunpowder was in information carrying capacity by means of which military use and had a profound effect on all future mines can be find.
As search and removal of conflicts.
In order to cause greater destruction By buried land mines is serious and problem faced by experiments had been conducted in the use of many countries, specially countries like landmines in Sicily and southern Italy.
This type of http: Firsty the gunpowder used in landmine was able to absorb moisture and water from air which consequently losses it's explosive ability. A glass tube in the cross piece held the detonating compound. A thin steel rod in the long part of the T had one end resting on the glass tube; the other projected about a 1. When someone lift foot and put it down on the rod broke the glass tube and detonated the Fig.
This was first mines designed to main rather than to kill indirectly. Reference to these mines was made during the Battle of Williamsburg in , where they adapted shells so as to surprise the Union vanguard.
When 1 Metal detector method the charge exploded, the light sides of the case 2 Biological method were blown out.
The Americans are really the first 3 Mechanical method nation to develop and use operational landmines. Then in he ordered his troops to prepare Metal detector methods: This method 1. But problem is plastic landmines cannot be detected by this method.
Mines only began to appear on a large scale in , as new piece of weaponry the assault antitank. To combat the growing number and effectiveness of American tanks, the German Fig 2. Initially they used large gun powder shells dug into the ground and 1 Introduction of coil imaging sensor: But these mines This sensor creates the image of an object instead proved to be unreliable and time consuming. In of producing audio signal .
Now days we able to early the produced a mine that could detect and see metal parts of less than 1cm but this effectively be used against tanks . Magnetic field of this may tend to of radar bullet is to find landmines without setting penetrate the ground and ground significally foot into the ground.
Microwave band have very distributed the magnetic field; which is measured large information carrying capacity thus internal by the magnetometer. This method is more structures of radar bullet consist of microwave sensitive to noise. Microwave emitter emits the Strengths: The bullet emits a Image resolution is poor. Horizanal range is limited. This pulse strikes There is risk to life of man who handles the metal the mine and its image gets available on the detector.
Biological methods: Also during wartime mines implanted by our enemy countries are to be detected and diffused properly in order to save the lives of our soldiers. So we should say that detecting landmines is important for every country today. Unfortunately India, Pakistan, Srilanka, Myanmar are in the list of less mine affected countries besides other countries. The purpose of a landmine is to disable, immobilize or kill.
It is an explosive device activated either by a person or vehicle or by command detonated by electric wire or radio signals. Most land mines are laid on just below the surface of ground and are activated by pressure or trip-wire.
Usually most of the land mines will contain many metallic parts, which can be made use of in their detection. This weapon is particularly cruel on children whose bodies being smaller and closer to the blast are more likely to sustain serious injury.
The severe disabilities and psychological traumas that follow the blast- means these children will have to be looked after for many years. A child injured at the age of 10 will need about 25 critical limbs during there life time. This cost in Dollars a huge sum to pay in countries where people earn as little as 10 dollar a month. Between of the red crores fitted over 70, amputees with critical limbs and the land mine problem in still growing.
There for considering these factors the discovery of radar bullet is really a big boost to our world as we launches to 21st century.
Metal detection 2. Explosive detection 4. Manufactured mines have casting made from a variety of materials including wood, metals, Plastic metal or other synthetic materials.
From the detection standpoint, metal is the easier component to detect. However some mines are metal free on certain virtually non-metal. These non-metals challenge the capacity of current metal detectors. Detecting explosives however is a complicated process. Modem airports have explosive detecters, which can detect small traces of explosives in suitcases and other containers. Explosive detection under field conditions has recently become the preview of mine detection dogs.
In all the above said methods mine detection in conducted in close proximity. That is detection is conducted after going very near to the mine. This method can prove to be dangerous in many occations. So it is not considered to be the safest method.
A preferred method is to use detection devices that locate land mines at a safe distance from the deminer. Ones the threat is located, that is mines are pin pointed, we can deactivate it safely.
This is where the importance of mine detection using radar bullet comes. The radar bullet is a special type of bullet. The main use of radar bullet is to find landmines without setting foot on the ground. This consists of firing a special bullet in to the ground from a helicopter, which could pin point buried land mines. The bullet units a radar pulse as it grounds to a halt.
This pulse strikes the mine and its image gets available on the computer in the helicopter, offering a safe and efficient way of finding land mines. Radar is a sensor. Radar makes use of radio waves to detect and locate objects. The purpose is to provide estimates of certain characteristics of its surroundings most commonly the presence, position and motion of aircrafts, ships and other vehicles. Radar operates by transmitting electro magnetic energy into the surroundings and detecting energy reflected by object.
If a narrow beam of this energy is transmitted by the directive antenna, the direction from which reflections come and hence the bearing of object may be estimated. In radar bullet principle the change of medium by the waves must be taken into consideration.
The transmitter will transmit an electro magnetic signal through the antenna, which will hit the target and reflects back. The bullet in designed in such a way that it gives out powerful blast of radio waves from under the ground.
The bullet will produce a pulse of radio waves as it pierces the ground and signal is reflected from any landmines within about a 15 meter radius will be detected by an antenna on the helicopter. And if the bullet hits it, it would explode.
As the bullet leaves the gun, there is a battery generating a magnetic field in the cylinder. When the bullet smashes into the ground ,the sudden deceleration forces the cylinder out from inside the coil.
The sudden movement of the metal cylinder through the magnetic field induces a large pulse of current in the coil. The coil thus acts like an antenna converting the pulse into a short burst of high frequency radiation. Almost 10 times move power than a standard ground penetrating radar from 20cm down.
For ordinary penetrating radar, little radiation penetrates the soil, most is reflected by the ground because of the sudden change in density between the air and the soil. Here the radiation has to change the medium twice. First from air to ground, and then after reflection, from ground into air.
But in radar bullet principle the radiation has to change the medium only once i. For example:
