Abstract

In this paper, Microwave doppler radar sensor operated in 10.525GHz is designed by dielectric resonant oscillator. According to doppler effects, a characteristic of Microwave sensor with FMCW was analyzed. The qualities of objects velocity and distance between object and microwave sensor by sensor output frequency difference was measured. As a result of Microwave doppler radar sensor, the prototype sensor is available for indoor burglar alarms and other application through FMCW signal.

본 논문에서는 10.525GHz에서 동작하는 마이크로파 도플러 레이더 센서를 설계/제작하였다. 움직이는 물체를 이용한 측정을 통해 도플러 효과에 따른 센서의 특성을 연구 분석하였으며, 측정 결과를 통해 물체의 속도와 물체와 센서 사이의 거리에 따라 특성에 주파수의 차이를 보임을 알 수 있었다. 측정된 결과를 이용해 마이크로파 도플러 레이더 센서의 FMCW 신호에 의하여 댁내 보안탐지와 같은 용도로 활용할 수 있다.
