전세계적으로 건강에 대한 관심이 증가되어 기존 의료 장비보다 편리하고 정밀한 비접촉, 실시간 헬스 모니터링 시스템 개발이 요구되고 있다. 그러므로 우리는 UWB(Ultra Wide Band) 레이더를 통해서 인체에 비접촉, 연속적으로 혈관의 운동 신호를 수집하고 이 수집된 데이터를 실시간적으로 신호처리해서 맥박, 수축기 혈압, 이완기 혈압을 측정할 수 있는 임베디드 기반의 전파를 이용한 혈압 모니터링 시스템을 개발하였다. 이 시스템은 임베디드 기반 GUI(Graphic User Interface)의 프로그램을 통해서 UWB 레이더 및 제어 시스템을 모니터링하면서 정확한 정보를 실시간으로 LCD(Liquid Crystal Display)에 표시한다. 임베디드 시스템은 소형화를 위해 제한된 자원을 사용해야 하기 때문에 기존의 PC GUI 설계 모드는 상대적으로 더 큰 메모리를 사용하므로 임베디드 시스템에 적합하지 않을 뿐 만 아니라 더 많은 CPU(Central Processing Unit) 처리시간을 요구한다.
