EMC Design Of Airborne Equipment

With the development of modern science and technology,a variety of electronic equipment has been very widely used in people's daily life.These devices,which usually produce some useful and useless electromagnetic radiation at work,may cause the performance of sensitive electronic equipment to decline or damage.On defense,there are more and more requirements of the function and performance of the fighter.Airborne electronic equipment is highly integrated and miniaturization is an inevitable trend,in order to achieve the limited space in the body to complete a variety of complex functions.These designs produce more complex electromagnetic interference signals when bring a significant increase in device functionality and performance.These interference signals will lead to the military aircraft avionics system performance is affected,while the aircraft will use the combat caused great security risks,if the system's electromagnetic compatibility design does not meet the requirements.In this thesis,the EMC design of the airborne electronic equipment is based on the development of a certain type of airborne electronic equipment in China.Firstly,The three elements of electromagnetic interference transmission are introduced,when the introduction of electronic engineering in the basic concepts of electromagnetic compatibility and basic principles,and the basic direction of the electromagnetic compatibility design is determined.Then,the basic principles of filtering,shielding,grounding and other applications in electronic engineering are introduced by means of time domain control and communication path control.Finally,this paper puts forward the design specification with the EMC design of a certain type of airborne electronic countermeasure equipment.
