Abstract

We realized a wireless multiple integrated laser engagement system composed of personal area network using Zigbee. The wireless laser detector had function of analog signal processor, decoder and wireless communication. However, it should consume low power and be small and light in order to be attached to a soldier's body. The decoder was realized in software to be small and light. We induced low power consumption as reducing the load of system using a narrow band optical filter. The fabricated wireless laser detector functioned well in optically noisy environment. Although the communication to the player unit through the wireless personal area network was dependent on the attachment place it was perfectly worked with transmission power of -40.2dBm or more.

ZigBee를 이용한 개인영역망으로 구성된 무선 다중 통합 레이저 교전 시스템을 구현하였다. 무선 레이저 검출기는 아날로그 신호처리, 해독 및 무선통신 기능을 갖추어야하는 반면 병사의 신체에 부착될 수 있도록 저전력소모, 소형 및 경량화 되어야한다. 소형 및 경량화를 위해 해독기는 소프트웨어적으로 구현하였고, 협대역 광학 필터를 이용하여 시스템의 부하를 줄여줌으로써 저전력화를 꽤하였다. 제작된 무선 레이저 검출기는 광잡음 환경에서도 정상 작동하였다. 무선 개인영역망을 통한 PU(Player Unit)와의 통신은 무선 레이저 검출기의 부착 위치에 따라 다소 차이가 있었으나 -40.2dBm이상의 출력으로 송신할 경우 100%의 수신율을 확보할 수 있었다.
