Construction of Emergency Microwave Communication Link Using Geographic Information
摘要
Abstract
Emergency microwave communication link is always unable to quickly build. To solve the prob-lem,a multi-attribute comprehensive evaluation method is used. According to existing geographic elevation and coordinate data,the method first judges the condition of line-of-sight( LOS) distance transmission be-tween two microwave communication equipment and then searches the relay stations in a certain range. Af-ter attenuation prediction, distance calculation and angle estimation, Technique for Order Preference by Similarity to an Ideal Solution( TOPSIS) is used to sort all the alternative relay stations in order to get the optimal relay station. Finally,the links between all equipment is built and the power applicability is evalua-ted. Simulation and evaluation results show that the proposed method can be used to construct communica-tion link in random areas and the received power of the communication equipment is greater than the re-ceiver sensitivity -120 dBm,which proves that the method of link construction is effective and adaptable.关键词
