- TITLE OF INVENTION : " A System For Detecting, And, visualizing Mines Including The Plastic Ones, Buried Underground By Thermal Imaging " .
- This description includes both the old system (the present in use), the existing deficiencies, and, problems of the old systems in use, the innovative inputs, and, the full description of the invention, and, its modus operandi, as follows:
1 - The Existing Systems in Use :
Mines are made mainly of high explosive materials, that are kept into metallic, wooden, plastic, or, glass hubs, and, such mines are usually buried under ground, whereas some of them are anti personnel, anti vehicle, or, anti armor, and, are distinguished by big size, and, the containment of a large amount of explosives, and, on being stepped over by personnel, vehicles, or, armored vehicles such as tanks, or, APC's, they blow up causing the killing of thousands civilians, militaries, and, animals annually, whereas the number of mines implanted in so many countries, particularly in the third world countries, may exceed 150 million mines, and, where the varieties may reach 100 types of mines (review figure 1/6 ), and, yet detecting the buried landmines, along with war scraps ( bombs, rockets, and, missiles) is carried out by the following methods:
1.1 - Probes ( iron rods with a pointed ends, or, a spear like rod), which are used in sandy, and, earthy, or, dusty grounds, that's in case of lack of detecting devices, and, in a limited ratio of cases, where there's a high risk of the mine to blow up in the probe user.
1.2 - Metal detectors, which is used with mines whose hubs are only metallic mines, and, not with plastic, or, glass mines.
1.3 - Mines sniffing dogs, which are almost killed during the process.
1.4 - Bees, and, rodents (rats, mice, and, Jerboa), whose use is still under research, and, not in use currently, until confirming their capability in that field, a matter that leads to the death of so many individuals working in the career.
1.5 - Mobile radar devices ( carried by the operator ), which emit electromagnetic energy of certain frequency through guided antenna, and, receive the responding waves, and, analyse them to produce a warning (alarm) of probable explosive material, and, where such devices are controlled by the operators, to get the best probability of explosive, mines, or, none in the searched area, and, where such devices are considered the best among so many means of mine detection, yet in case of non sensing the mine, the result would be a blow up, and, death of the operator, and, his colleagues (review figure 2/6 ) .
and, yet after detecting, and, retrieving the mine, it could be blown up owing to its instability, and, burial place. - Problems With The Present System :
Such problems are embodied into that all the aforementioned methods don't give the operator the chance to eye view the buried mine on detecting it, while the only efficient dependable method is currently the mobile radar, mingled with metal detector, which doesn't give an eye spot of the burial location, and, only dependable in reading the mine existence probability, while its problem is that it gives an erroneous reading of imaginative mine, that may lead to digging, or, exploding the spot, and, the wasting of time, effort, and, money in vain. - What's New In The Invention:
Lately, thermal cameras have become a common place in industry, after a long time of use on military field, and satellites only, by the use of IR rays (thermal rays) emitted from bodies, and, it's well known that thermal cameras image the outer crusts, yet in this invention these cameras will be used in imaging the core (under ground) to detect buried objects . (review figure 3/6 )
whereas the novelty is the use of thermal imaging technology to detect under ground mines, after heating the ground by the use of a suitable heating means such as halogen lamps of high power, or, the high power IR lamps, where the ground temperature is raised by 2 to 5 Celsius, or, more, and, thus on letting ( 5 Second ) the ground to cool, imaging begins, by the retrieval of the IR waves, use thermal cameras, thus all the buried objects like stones, metals, or, mines appear on the screen, up to their thermal qualities, represented in:
3.1 - Speed of thermal absorption of the object, at heating .
3.2 - The object capability to store heat during heating. 3.3 - Speed of ray radiation in the form of IR rays on cooling.
3.3 - Sum of heat radiation from the hot objects on cooling.
Yet, for the different thermal qualities of the objects, consequently, there would be a differentiation in temperature on cooling the hot materials ( objects ) , giving the thermal camera a chance to discriminate materials on imaging, Along with the qualities of IR rays radiation from the heated objects, and, which break through sands, earth, and, dirt . ( review figure 4/6 ) - Detailed Description of The Invention, and, Its Modus Operandi :
4.1 - Invention's composed of a highly sensitive thermal camera ( measures sensitivity < 45 mk ), attached with a high power halogen lamp ( 500-1000W ), or, a high power IR lamp ( 250W ) for heating the ground, and, are carried on a small car moves by a rubber belt (review figure 5/6 ) which is wire/wireless remotely controlled, and, this combination as well could be carried by an unmanned helicopter which is wireless remotely controlled, (review figure 6/6 ).
4.2 -The carrier is guided to the detectable area, or, location by the use of a GPS device to begin heating the ground .
4.3 - The heating lamp (halogen, or, IR) is focused from a height of
1-1.5 m, and, for 5-10 minutes up to the ground quality (sandy, earthy, rocky, or, muddy), and, up to the depth required to search.
4.4 - Shut down the heater for 5-10 seconds to permit cooling, and, rays radiation, and, then begin imaging, thus all the under ground objects will appear on the screen including mines, and, war scraps, including plastic mines, and the image will be similar to X-rays images, while to determine the depths, an auxiliary sonar system could be used like the medical sonar (ECHO).
4.5 - A mobile video camera could be added to the system (DOM) to give the operator an image of the mines, while an ordinary camera is used to help the carrier guide to do his job, and, to detect surface mines, which emerged by the wind action.
4.6 - To receive both the thermal, and, the ordinary images, a cable is used to transfer them between the system vehicle, and, the operator, and, in the case of an aerial carrier, a video emitting device is used to wireless transfer of the image to the operator ( review figure 4/6 ). 4.7 - For the neat detection we should select a highly sensitive thermal camera, and, determine the heating lamp power, the heating time, and, the height of the heating lamp, up to the ground, quality in order to determine the imaging depth.
while more than one lamp could be used for heating the ground, and, as well a group of more than one thermal camera.
