Abstract: A method for simulating electromagnetic interactions between an antenna with a reflecting front face and at least one electromagnetic radiator and an electrically large interaction structure placed in front of the antenna comprises providing an antenna model representing the antenna, the antenna model comprising an antenna surface representing the front face and at least one field source representing the at least one radiator, wherein the field source is placed at the antenna surface and is configured as a far field source that is defined by a predetermined radiation pattern, and wherein direct electromagnetic interaction between the field source and the antenna surface is avoided. The method further comprises determining electromagnetic radiation launched by the field source based on the predetermined radiation pattern, propagating the radiation using an asymptotic numerical method, and determining interactions of the radiation with the interaction structure and with the antenna surface.

Abstract: This document describes techniques and systems for enabling more-accurate single-point radar cross section (RCS) approaches for radar simulations without introducing orders of complexity. For automotive radar applications, considering variations in RCS radial patterns, with both angle and range, and because of analytically calculated multi-path effects and near-field RCS effects improves simulation accuracy by incorporating multi-path phenomenon that is present due to ground reflections. The described techniques are performed without using full scale ray-tracing or other computationally demanding techniques.
