This paper studies the influence and control of obstacles around the DVOR and propose the control methods by combining the standards and theories. First of all, according the relevant technical standards of GB6364-2013 and MH/T4003.1-2014 to control the height of obstacles, then perform modeling and simulation and analyze whether obstacles will affect the signal coverage of DVOR. In order to prevent attenuation, this paper strictly controls the height of obstacles based on the theory of signal propagation, the Fresnel Zone principle and Diffraction theory. The results show that technical standards are the minimum operating requirements when used. When we set the height of obstacles only reply on the technical standards, the signal will not fully meet the signal coverage of requirements. It is necessary to analyze and control the obstacles deeply according to actual condition.
