| Abstract: | According to the working principle of the course beacon in instrument landing system, relevant mathematic model was built up and simulation of the course beacon in instrument landing system under the ideal channel condition was realized by MATLAB tool. The receiving signal wave and difference in depth of modulation（DDM） when the course deviation occurs are gained by the simulation results, and the effect on DDM brought by the disturb signal under the condition of standard course is analyzed. |
