Abstract

In this study, the SLB(Sidelobe Blanking)/BLB(Blacklobe Blanking) design of the VHF band radar using the low-frequency band having a relatively larger beam width than the S-band or X-band radar. The antenna of the VHF band has a relatively large beam width, so it is reflected from the side lobe. If the reflected target signal is not processed into sidelobe, the false alarm rate of the radar increases by recognizing it from the main lobe signal. This method of SLB blocking is the elimination of the side lobe signal in the front of the array antenna using the central radiating element of the array antenna, and the blocking of side lobe signal from the antenna rear through BLB receiver block. After completed the radar implementation, The function of blocking of side lobe signals was confirmed through the system unit test by Simulated signal generator. Through this study, it will be used in the implementation of the side-lobe blocking technology of the array antenna for low-frequency band radar with large antenna size and beam width in the future.

본 연구는 S대역 또는 X대역 레이다 보다 빔폭이 상대적으로 큰 저주파 대역을 사용하는 초단파 레이다의 SLB/BLB 설계 및 구현에 대한 연구이다. 초단파 대역의 안테나는 빔폭이 상대적으로 크기 때문에 부엽에서 반사된 표적 신호를 처리하지 않으면 주엽 신호에서 들어온 것으로 인식하여 레이다의 탐지 오경보율이 증가한다. 부엽 차단 방법은 배열 안테나의 중앙쪽 복사소자를 사용하여 배열안테나 전면부의 부엽 신호를 차단하고, 뒤쪽에서 들어오는 신호는 BLB 수신안테나 조립체를 통해 차단시킨다. 레이다 구현을 완료하여 모의 신호 발생장치를 활용한 시스템 단위의 부엽 신호 차단에 대한 시험을 통하여 SLB/BLB 신호가 제거되는 것을 시험을 통하여 확인하였다. 본 연구를 통하여 향후 안테나 크기 및 빔폭이 큰 저주파 대역 레이다용 배열안테나의 부엽 차단 기술 구현에 활용할 예정이다.
