Hardware Design Of A Radio Direction Finding System

Radio-direction finding method develops with the research ofelectromagnetic wave and its application. This technology waswidely used in the field of civil and military areas. The real-timehigh accuracy goniometry can separate and identify the parameterof electromagnetism object.This paper aims to develop a kind of radio direction findingequipment adapting to various environments. The equipment canidentify the signal from typical electromagnetic environment. Thispaper adopts interferometer algorithm to realize direction findingand gives the results according to terminal system.Emphasis of this paper is to design and realize a hardwaresystem of direction-finder set. First a whole structural frame hasbeen designed. And modular circuit is designed based on thestructure of hardware system. In order to achieve betterspecification, improvement for the original designation has beenproposed, and the improvement has partially been completed.
