Abstract

The invention discloses an electromagnetic compatible digitized model system for a whole aircraft, which comprises an aircraft parameterized surface model construction unit (1), an airborne equipment position matching unit (2), an airborne equipment interference associated unit (3), an electromagnetic environment distribution unit (4) and a sensitive equipment interference source acquisition unit (5). The invention constructs the electromagnetic compatible digitized model system for the whole aircraft by adoption of the behavioral simulation method, application of the 'grey box' theory, consideration of characteristic parameters of electronic airborne equipment from the aspect of system level, neglect of various circuit details, and digitized modeling simulation of the electronic airborne equipment of the aircraft.

Description

technical field [0001] The present invention relates to the field of electromagnetic compatibility design, and more particularly refers to a digital model system applicable to the aircraft design process, which uses a behavioral simulation method to perform system-level electromagnetic compatibility on the entire aircraft. Background technique [0002] In the traditional aircraft electromagnetic compatibility design method, the overall design unit of the aircraft proposes performance index requirements for communication, navigation and other airborne electronic equipment based on the performance requirements of the whole aircraft. In the development or production process of airborne electronic equipment, functional requirements are mainly considered. To realize the design parameters, the electromagnetic compatibility interrelationship between the airborne electronic equipment is not fully considered; when the airborne electronic equipment is developed, the electromagnetic com...
