Abstract

본 발명은 레이다반사신호시뮬레이터에 관한 것으로, 레이다와 그 사용자를 테스트하기 위해 지상용, 선박용 및 항공기용 레이다시스템(16)에서 유용한 하나 이상의 원격물체를 나타내는 하나이상의 레이다반사신호를 발생하는 장치(10)이다.
이 장치는 필요한 경우 제이다(16)가 탑재되는 항공기의 실제 또는 사전프로그램된 운동에 상호작용할 수 있는 하나 이상의 반사신호시나리오를 발생한다. 반사신호발생장치의 작동을 정확히 하고 재현가능하도록 레이다 자체의 내부테스트신호(21)출력이 원격물체반사신호시나리오를 항공기레이다장치(16)에 적용하는 장치의 무선주파수부분을 수정토록 사용된다.
반사신호의 정밀성을 보다 개선하기 위하여 디지탈선입선출(FIFO 32) 지연수단이 레이다자체전송신호의 지연재사용을 정확히 허용하는데 이용된다.
