[0077] Such as figure 2 As shown, the civil aviation localizer antenna array rapid simulation system is used to accurately and quickly generate the channel CSB pattern, the channel SBO pattern, the clearance CSB pattern, the clearance SBO pattern, the course DDM, and the clearance DDM.

[0078] 1. Import feed and phase.

[0079] There are currently Normac7212, Normac7216, Normac7220, SELEX 20 / 10, SELEX 14 / 10, THALSE20 / 10 and other localizer antenna arrays in the world. Different types of antenna arrays have different feeds and phases. All antenna array feeds and phases are stored in xml file format. The file includes antenna array name, antenna array quantity, distance, CSB amplitude, CSB phase, SBO amplitude, SBO phase, Clearance CSB amplitude, clearance SBO phase, the distance of each antenna pair, and check whether the antenna array file is complete according to the antenna model.

Abstract

The invention discloses a rapid simulation method for a civil aviation course beacon antenna array, and solves the problems that in the prior art, errors are easily caused, the efficiency is low and incompleteness is caused due to the fact that a navigation direction beacon antenna array directional diagram depends on manual import in site protection and electromagnetic environment evaluation. According to the invention, the feed and the phase of a heading beacon antenna array are imported; an omnidirectional channel CSB, an omnidirectional channel SBO, an omnidirectional clearance CSB and anomnidirectional clearance SBO are generated, a 360-degree directional diagram of an antenna oscillator is imported, the directional channel CSB, the directional channel SBO, the directional clearanceCSB and the directional clearance SBO are finally obtained, and finally a channel DDM and a directional clearance DDM are generated. According to the method, the channel CSB directional diagram, the channel SBO directional diagram, the clearance CSB directional diagram, the clearance SBO directional diagram, the channel DDM and the clearance DDM can be accurately and quickly generated, and meanwhile, the correctness and integrity of manually collecting the channel and the clearance directional diagram can be effectively improved.

Description

technical field [0001] The invention relates to a fast simulation method for a civil aviation direction beacon antenna array. Background technique [0002] Civil aviation instrument landing system equipment is very important equipment to ensure aviation safety, and it is currently the only navigation equipment in China's civil aviation that can support precision approaches. The localizer, one of the components of the system, is responsible for the horizontal guidance of the aircraft during precise approach, and the glide beacon is responsible for the vertical guidance of the aircraft during precise approach. [0003] The main work of the localizer site protection and electromagnetic environment assessment is to study the influence of obstacles on the localizer signal. One of the necessary tasks needs to import the direction diagram of the localizer antenna array into the system to provide the basis of the antenna array for signal analysis. Model. [0004] At present, there...
