Analysis Of The Scattering Character Of Airborne-antennas By UTD Method (Case Of Cylinder)

Electromagnetic compatibility (EMC) is a key standard in the military facilityand system, because it determines weather the integral part of weapon facility canwork normal. Nowadays, the electronic facility installed on various kinds of airplanesis large and complex, which make the electromagnetic environment complex and thetechnique difficult. Especially the radar antenna and the electromagnetic compatibilityof the system installed on it is the key problem in the difficulties. The exact theoryanalysis and antenna installing place prediction at the first phase of the antenna designand installation contents the requirement of not only airplane pneumatic character butalso the respective military standard and the electromagnetic compatibility betweenthe antennas in this project. The base theory of this thesis is uniform geometry theoryof diffraction, which is one of the most flexible methods of high frequency analysis inthe electromagnetic theory. On the base of deep research of this theory, the geometrydiffraction solution of some typical geometrical part such as board or column issummarized systemically, which make it more practical and easy to compute program.The actual computing example is given to prove the correctness of this theory in manyways. This work is the unavoidable part in the airborne-antennas electromagneticcompatibility analysis. In the last chapter, the scattering pattern of the monopoleantenna installed on the certain airplane is given.
