Reduction of Time and Costs for Antennas Integration Through Computational Electromagnetism
Abstract
Modern combat aircraft increasingly incorporate more and more operational functions. These functions use a wide range of frequencies over the entire electromagnetic spectrum. They are essentially related to three functions areas, which are: Radar function; Electromagnetic Countermeasures (ECM); Communication Navigation Identification (CNI). Each of these functions calls upon a whole suite of equipment units, to ensure the necessary processing, and of antennas, to ensure the associated radio-electric coverage. Each function has its own antenna, or set of antennas, which, more particularly in the case of the ECM and CNI functions, makes it obvious that: such antennas form protuberances, becoming less and less compatible with the aircraft's global performance characteristics (drag, RCS,...); the great number of them makes installation, more and more costly. Also, in the case of the Radar function, the antenna, whether of parabolic, mechanical scan or of active, electronic scan type, is generally positioned on the aircraft forebody, with the consequence that the restricts the obtained coverage and furthermore, wastes a "precious" location which could be profitably used for other functions To handle this increasing complexity, new technologies and tools are required which reduce time and cost of the system integration on aircrafts.
