Domain decomposition techniques applied to radar front-eend modeling

Modeling of active electronically scanned phased array antennas is a real challenging problem which needs, due to the complexity of the antenna, the use of a lot of different techniques. One of the key technique is the domain decomposition method which allows to split the global problem into several smaller problems without loosing accuracy. The purpose is to present the modeling methodology based on this technique and used by Thales Syste¿mes Ae¿roporte¿s to simulate active array antenna.
