Abstract: A radar sensor comprises a radar transmit and receive unit configured to transmit radar waves to an external environment of the vehicle and to receive radar waves from the external environment of the vehicle, and an interface unit attached to the radar transmit and receive unit. One or more design and/or material parameters of the interface unit are adjusted to fit a predetermined installation position at the vehicle with respect to desired characteristics of the transmitted and received radar waves. A corresponding method for integrating a radar sensor in a vehicle is also disclosed.

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.
