Automotive radar is a key sensor system enabling object detection and tracking. While an unmounted radar has ideal characteristics, this is not the case when the radar is integrated inside the vehicle - the vehicle body and other components in the vicinity, such as the bumper, chassis, or cables, influence the electromagnetic waves emanating from it and deteriorate its performance. In such a scenario, electromagnetic simulation can be utilized for incorporating design changes in the early stages of product development. Due to the very high-frequency application (around 77GHz) and the large electrical size of the complex structures around the sensor, ideal simulation techniques are required to optimize the radar integration scenarios. Hence, the key challenge here is to arrive at the optimal trade-off between accuracy and computational resources/simulation time.
MODSIM-based simulation-driven design is the key here, as such an approach is instrumental in breaking down the silos between design, modeling, and simulation to accelerate the entire product development cycle and lower the cost.
The presentation will outline how radar vehicle integration is enabled from an electromagnetic standpoint and how optimal solutions are derived by leveraging RF simulation using SIMULIA CST Studio Suite®. Various radar vehicle integration scenarios and associated RF simulation workflows will be detailed to illustrate how the key challenges are tackled.
