Abstract:
Efficient and optimal design of radar-based Advanced Driver Assistant Systems (ADAS)
needs the evaluation of many different electromagnetic solutions for evaluating the impact of the
radome on the electromagnetic wave propagation. Because of the very high frequency at which these
devices operate, with the associated extremely small wavelength, very fine meshes are needed to
accurately discretize the electromagnetic equations. Thus, the computational cost of each numerical
solution for a given choice of the design or operation parameters, is high (CPU time consuming and
needing significant computational resources) compromising the efficiency of standard optimization
algorithms. In order to alleviate the just referred difficulties the present paper proposes an approach
based on the use of reduced order modeling, in particular the construction of a parametric solution
by employing a non-intrusive formulation of the Proper Generalized Decomposition, combined with
a powerful phase-angle unwrapping strategy for accurately addressing the electric and magnetic
fields interpolation, contributing to improve the design, the calibration and the operational use of
those systems.
