VHF 대역의 전자파를 사용하는 지하 레이더의 적용 범위는 넓으며 지하 공극 조사 및 고고학 탐사를 포함합니다. 더 넓은 적용 범위를 달성하려면 조사 깊이가 더 깊어야 합니다. 본 논문에서는 이러한 요구사항을 충족시키기 위한 방법 중 하나로 처프 신호를 이용한 펄스 압축 방법에 대해 설명하고, 그 장점과 문제점을 논의한다. 먼저, 펄스 압축의 처리 방법으로 지연 상관(Delay Correlation) 방법을 제안한다. RF 대역 처프 신호를 펄스로 직접 변환합니다. 게다가, 이 방법은 S/N 기존 펄스 레이더에 비해 40dB 이상의 비율을 제공합니다. 따라서 더 적은 송신 전력을 사용하더라도 기존 펄스 레이더와 동일한 탐지 능력을 갖습니다. 다음으로 처프 신호에 대한 RF 증폭기 포화 및 지하 전파 특성의 영향에 대해 논의합니다. 둘 다 방법의 검출 능력에 거의 영향을 미치지 않는 것으로 나타났습니다.

Abstract: The application of subsurface radar using electromagnetic waves in the VHF band is wide and includes surveying voids under the ground and archaeological prospecting. To achieve a wider application range, the survey depth must be deeper. In this paper, a method of pulse compression using a chirp signal as one of the methods to fulfill this requirement is described, and its advantages and problems are discussed. First, a delay correlation method is proposed as a processing method of pulse compression. It converts RF band chirp signal directly into a pulse. Moreover, the method improves the S/N ratio by over 40 dB compared with conventional pulse radar. Therefore, it has the same detection ability as conventional pulse radar even though it uses less transmitting power. Next, the influences of RF amplifier saturation and underground propagation characteristics on the chirp signal are discussed; both are shown to have little influence on the detection ability of the method.
