Abstract

In this development, By using the phase array antenna, the beam around was electronically revolved and the marine fixed type radar of which the detection is possible was made and the check around was tested. There are the risk of the corrosion because of the abrasion of the axis of rotation and salinity with the way that the existing marine pulse radar detects the check by using the mechanical rotation. Besides, the maintenance cost of the magnetron gets to happen by using the detection signal. In this development, The fixed type radar of the low output which revolves electronically around the beam by using the radar signal processing method of the phase array antenna using the phase shifter and FMCW(Frequency Modulation Continuous Wave) method was made. And by using the fixed type radar, the check detection test was conducted.

본 개발에서는 위상 배열 안테나를 이용하여 전자적으로 빔을 회전하여 주변의 물표를 탐지할 수 있는 선박용 고정형 레이더를 제작하여 테스트하였다. 전자적인 회전 방식을 사용하는 고정형 레이더는 기존의 선박용 펄스 레이더의 문제점인 염분 및 해풍에 의한 부식과 회전축 마모문제를 해결할 수 있다. 또한 본 과제에서는 저출력 방식의 탐지방식인 FMCW 방식을 사용함으로써 고출력 레이더 사용으로 인한 인체에 대한 전파 피폭 문제와 마그네트론의 유지보수 비용 문제를 해결 할 수 있을 것으로 기대한다.
