Active Electronic Scan Array (AESA) radars have replaced standard mechanical scan radars since the end of the last century. AESA are typically composed of thousands of elements and are “flush-mounted” on integrated structures. These features introduce significant new challenges and require new solutions in the field of computational electromagnetics (EM).
The main objectives of the EM modeling of AESA concern:
In computational electromagnetics, solving this general problem and related issues is the current focus. Some of the matters are related to the complexity of the arrays themselves (hundreds/thousands of elements) and the presence of a large range of geometrical scales (from mm’s to tens of meters); some are associated with flush-mounting and the relevant E.M. coupling physical mechanism (creeping-wave, no more simple space waves); and others regard typical operational requirements (i.e., required high accuracy).
IDS has been traditionally devoted to developing innovative modeling procedures dedicated to high fidelity AESA EM modelling and analysis, overcoming the capabilities found on the commercial market through the provision of the main solvers, procedures and postprocessors integrated into IDS frameworks.
