Watson - Watt Measured The System Of Short-wave Monitoring System

Combined with the newly developed Short-wave Monitor and Meterage System, the paper gives a thorough investigation on short-wave diffuse theory, radio direction detecting technology, DSP theory, Software Radio theory, ect.Firstly, the paper studies radio direction finding theory, and makes comparison among the existing direction finding systems. It also puts forward the ideas of an advanced short-wave monitor and meterage system to satisfy requirement, and introduces the research emphasis of the paper.Secondly, it provides the technological requirement and the whole device frame. The process of development is illustrated by software and hardware (emphasis on software) .It also provides the introduction of DSP, frequency scan, channel scan, radio direction finding and signal analysis, ect.In this paper, the collecting of azimuth information based on Watson–watt and signal analysis are introduced in detail. The modification of azimuth that is at the bottom of environment error is provided.The result of experiment indicates: the designed prototype comes to the requirement of technical features.
