Automotive OEMs are moving towards the inclusion of several safety systems, which are covered by several sensors. Many new functions are being added to assist the driver to avoid accidents that might be caused by different road scenarios. The new ADAS (Advanced Driver Assistance Systems) systems are mainly: lane change assistants (LCA), blind spot detection (BSD), pedestrian recognition, collision avoidance and pre-crash functions, cross traffic alerts and parking assistance. Automotive Collision Avoidance Radars operate at 77GHz band. Radar design and integration at such high frequencies is very challenging. As a result, electromagnetic (EM) simulation is applied to avoid time consuming and expensive prototyping cycles for the radar manufacturer and a complex radar integration behind a car‘s bumper for automotive OEMs. In this talk, a detailed design process for automotive radar design and integration will be presented using Altair’s advanced EM simulation solutions. Also, this talk will present simulations of radar channel and the environment for better understanding of the functioning of the radar in real driving scenarios using virtual drive test simulations using Altair’s advanced simulation solutions.
