Abstract

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.

본 논문은 지뢰탐지용 48채널 배열 UWB 임펄스 레이다 방식의 지면투과레이다 구현과 시험에 대해 기술한다. 지면투과레이더는 기존 금속탐지기의 한계인 비금속 지뢰 탐지의 어려움과 매질 내 금속 성분에 의해 발생하는 높은 오경보 문제점을 극복한다. 본 논문에서는 펄스폭이 600ps 급인 미세한 모노싸이클(Monocycle) 펄스 파형을 사용해, 높은 해상도의 지뢰 전자파 영상을 제공토록 시스템을 구현한다. 특히 신호처리를 통해 지뢰가 매설된 지점을 자동으로 추정하고, 해당 지점에서의 분할된 상세 지뢰 전자파 영상을 사용자에게 제공한다. 기준 성능 분석을 위해 한국 대표 토양인 거친 사양토를 사용한 실내 시험장을 구축하고, 시험장 내의 자동화된 측정 플랫폼에 구현한 레이다를 장착하여 영상 획득 및 탐지심도 분석 등의 시험을 수행한다. 지뢰는 비무장 지대에 매설된 지뢰와 동일한 형태의 모형 지뢰를 사용한다.
