Digital Design Of Radio Compass Navigation System

The main content of this paper is the digitization of the radio compass navigation system.Generation and reception of the radio signal are designed on the simulation platform.After the software simulation is completed,the digital design of the radio compass navigation system is carried out.The paper introduces designing of the circuit diagram,selecting of the appropriate device,making of the PCB,and testing of the data.The results of the acceptance indicate that the radio compass navigation system meets the design criteria.This paper introduces the development status of radio compass navigation system at home and abroad,and introduces the basic theory of software radio technology.Start with the radio semi-compass,introduce its navigation principle,and transition to the radio compass.The antenna composition and signal format of the radio compass are introduced in detail,and the antenna pattern is also analyzed.The simulation of signal transmission and reception on the VS2010 and MATLAB joint platform tests the azimuth reception accuracy and introduces the key technologies used by the processing end.The structural block diagram of the digital design of the system is proposed,which is transformed into a circuit diagram and the design of each part is carried out.The problems that often appear in PCB design are highlighted,and the main rules of PCB design are described in detail.Use a variety of methods to reduce system interference and improve system performance.The PCB design points mentioned above are combined with the actual use of the system.Introduce the host computer interface,test the manufactured hardware devices,analyze the obtained data,and verify that the performance of the designed radio compass navigation system meets the design requirements.
