摘要
微波遥感可以实现全天时、全天候的对地观测,因此在林火探测的技术领域具有一定的优势。为了采用测定火焰微波辐射强度的方式来判断火灾发生的区域,先后分析了火焰的微波辐射和微波接收原理,并对宽频微波探测接收系统进行了方案设计。为满足应急或灵活探测的需要,对低空平台的GPS接收单元和惯性导航单元进行了组合设计,以确保林火微波探测的可靠性和稳定性。
Microwave remote sensing can be achieved throughout all-day and all-weather land observation. So, the microwave technology has certain advantage in forest fire detection field. In this paper,in order to determine the fire happening region, the theories of microwave radiation and receiving were analyzed, and broadband microwave receiver system solution was designed. So as to meet the needs of emergency and flexibility detection, GPS receiver module and inertial navigation unit in low-altitude platform were designed to ensure the reliability and stability of microwave forest fire detection.
