Quick and precise detection and alarm to Foreign Object Debris （FOD）are significant issues for airplane′s safety.An effective FOD detection and surveillance system for runway is an important part of airport security system.Based on the performance requirements of FOD detection and surveillance system and other nations′ experiences,through the detail analysis of millimeter-wave radar system,optical system and their data interaction,a new FOD detection and surveillance system is presented.The interface of software is promoted.The system,which can classify and warn FOD all the time and under all-weather condition,will prevent and reduce threaten from FOD to airport runway.
