Problems solved by technology

Although the ray tracing method can perform efficient approximate calculations on DDM, since the electric wave is equivalent to a ray beam during the calculation process, when the electric wave passes through an object with a similar size and wavelength, it is easy to produce inaccurate simulation data.

Abstract

The invention discloses a disturbance simulation method of an instrument landing system. The method comprises the following steps: S100, acquiring an actual simulation region of an airport and the site environment of the actual simulation region so as to construct an electromagnetic environment model of the airport; S200, constructing a parallel implicit local one-dimensional time domain finite difference mathematical model; S300, solving the parallel implicit local one-dimensional time domain finite difference mathematical model through a cloud computing platform to obtain the electric fieldvalue of the electromagnetic environment model; and S400, obtaining the difference in degree of modulation according to the electric field value. The disturbance simulation method of the instrument landing system, disclosed by the invention, lowers the complexity of computation, reduces the data transmission among nodes and reduces the bandwidth pressure, so that the instrument landing system canbe normally used on a cloud platform.

Description

technical field [0001] The invention relates to the field of civil aviation equipment, in particular to an instrument landing system disturbance simulation method. Background technique [0002] With the development of the aviation industry, the number of global flights is gradually increasing, and the impact of bad weather on the punctuality of flights is becoming more and more serious. The instrument landing system has attracted more and more attention from air traffic control. Instrument Landing System (ILS, also translated as instrument landing system, blind landing system), is the most widely used aircraft precision approach and landing guidance system. Its function is to realize the localizer and glideslope guidance by two beams of radio signals emitted from the ground, and establish a virtual path pointing from the runway to the air. The aircraft determines its relative position with the path through the onboard receiving equipment, so that the aircraft can move along ...
