| Abstract: | This paper investigates the computer-aided analysis for field strength prediction of ultra short wave on irregular ground in communication service area.The paper depicts the way for establishing the digital terrain data library of the service area,drawing the terrain section map of communication path,judging the propagation type and calculating the propagation loss by the computer.The field strength distribution map of the service area can be drawe by the software based on the user's requirement. |
