Landmines are a humanitarian challenge because they indiscriminately kill and maim civilians. Landmines are weapons that cannot distinguish between a soldier and a civilian, and they remain active for decades. As a result, most of the victims of mines are innocent men, women and children. For this purpose, new technologies such as a methode of landmine detection and mobile robots are needed. Our effort is to develop a small mobile robot for landmine detection, to detect landmine and to explore the landmine distinguishable method. In this paper, Specifically we detected landmines using electromagnetic sensors and distinguished metals from M14 antipersonnel mines under the ground using 6 step creativity of the TRIZ. Therefore, we proposed new method of landmine detection using the TRIZ.

지뢰 제거에서 가장 중요한 요소는 지뢰의 탐지인데, 현재 이용되고 있는 장비들의 성능에는 나름대로 장.단점들이 있어 주로 미구기과 유럽에서 새로운 지뢰의 센서기술을 개발하려는 노력이 대단히 활발하게 이루어지고 있다. 캄보디아나 아프칸 등 전쟁 또는 내전의 후유증으로 제거되지 않고 방치된 무수히 많은 지뢰들에 의해 민간인들의 피해가 계속되자 UN을 중심으로 한 소위 '인도적 지뢰제거'(Humanitarian Demining)사업이 펼쳐지게 되면서 선진국을 중심으로 이 분야의 연구개발 예산이 늘어나기 시작하였다.

In this paper, we analyzed the performance of IoT based smart wearable mine detection device. There are various mine detection methods currently used by the military. Still, in the general field, mine detection is performed by visual detection, probe detection, detector detection, and other detection methods. The detection method by the detector is using a GPR sensor on the detector, which is possible to detect metals, but it is difficult to identify non-metals. It is hard to distinguish whether the area where the detection was performed or not. Also, there is a problem that a lot of human resources and time are wasted, and if the user does not move the sensor at a constant speed or moves too fast, it is difficult to detect landmines accurately. Therefore, we studied the smart wearable mine detection device composed of human body antenna, main microprocessor, smart glasses, body-mounted LCD monitor, wireless data transmission, belt type power supply, black box camera, which is to improve the problem of the error of mine detection using unidirectional ultrasonic sensing signal. Based on the results of this study, we will conduct an experiment to confirm the possibility of detecting underground mines based on the Internet of Things (IoT). This paper consists of an introduction, experimental environment composition, simulation analysis, and conclusion. Introduction introduces the research contents such as mines, mine detectors, and research progress. It consists of large anti-personnel mine, M16A1 fragmented anti-mine, M15 and M19 antitank mines, plastic bottles similar to mines and aluminum cans. Simulation analysis is conducted by using MATLAB to analyze the mine detection device implementation performance, generating and transmitting IoT signals, and analyzing each received signal to verify the detection performance of landmines. Then we will measure the performance through the simulation of IoT-based mine detection algorithm so that we will prove the possibility of IoT-based detection landmine.

Since a soldier manages a hand-held landmine detector by hands, it is necessary to develop a system that can detect the target quickly and accurately. However, the hand-held landmine detector used in Korea has a problem that it can only detect the metal mines. Therefore, it is important to solve the problem and to develop a hand-held landmine detection system suitable for the Korean environment. In this paper, we propose a hand-held landmine detection system suitable for the Korean environment using ground penetrating radar. The proposed system uses depth compensation, matched filtering, and frequency shifting filtering for preprocessing. Then, in the detection step, the system detects the target using the edge ratio. In order to evaluate the proposed system, we buried landmines in sandy loam which is most of the soil in Korea and obtained a set of ground penetrating radar data by using a hand-held landmine detector. By using the obtained data, we carried out some experiments on the size and position of the patch and the shifting frequency to find the optimal parameter values and measured the detection performance using the optimized values. Experimental results show that the proposed preprocessing algorithms are suitable for detecting all landmines at low false alarm rate and the performance of the proposed system is superior to that of previous works.

차세대 지뢰탐지 기술로는 NQR(Nuclear Quadrupole Resonance, 핵4중극자공명), GPR(Ground Penetrating Radar, 지상 침투 레이더)등 이 연구 및 개발 중 이다. 현재 우리나라에서도 이중 GPR을 차세대 지뢰탐지 기술로 연구중에 있다. 그렇지만 지금까지 개발된 GPR 기술을 적용한 지뢰탐지기는 얻어진 2차원 영상에 대해서 육안에 의한 식별만이 가능하여 지뢰 식별이 장시간 소요된다는 단점을 가지고 있다. 이에 본 논문에서는 그러한 문제를 해결하기 위해 주성분 분석법을 적용하여 해결하고, 제안된 시스템이 가능한지 확인하기 위해 유사한 실험 환경을 구성하고, 얻어진 영상을 학습시켜 실제로 얻어진 영상에 대한 분류가 가능한지를 확인하였다.

비무장지대에 매설되어 있는 100만여개의 지뢰와 북괴의 호전적인 태도를 감안한다면 전시에 전투력 발휘를 보장하기 위한 전력화 측면에서 그리고 인도주의적 측면에서 우리군도 정책적으로 추가적인 지뢰제거장비의 연구개발에 관심을 기울여야 하겠다. 지뢰제거장비는 1종류만 사용한다면 100% 지뢰제거에는 제한이 따르며 기계식, 전자기식, 폭파식, 비폭파식 장비를 종합적으로 운용하여 전시 기동부대에 기동성을 보장하고 또한 군사작전지역이 아닌 지역에서 지뢰로 인한 민간 사상자를 방지하고 통일에 대비할 수 있도록 지뢰탐지 및 제거장비개발 획득에 박차를 가해야 하겠다.

This paper describes the development of the ground penetrating radar (GPR) system using UWB impulse radar with 48 Channel array. GPR is an effective alternative technology to resolve th disadvantages of metal detectors. Metal detectors have a very low detection probability of non-metallic landmine and high false alarm rates caused by metallic materials under the ground. In this paper, we use the mono-cycle pulse waveform with about 600 ps pulse width to obtain high resolution landmine microwave images. In order to analyze performances of this system, we utilize indoor test facility that made up of rough sandy loam which representative Korean soil. The mimic landmine models of metal/non-metal and anti-tank/anti-personnel landmines buried in DMZ (demilitarized zone) of Korea are used to analyze the detection depth and the shape of the mines using microwave image.
