We demonstrate faster and efficient simulations of behind-the-bumper installed millimeter wave automotive radars using spherical modes. The spherical mode coefficients are extracted from the standalone radar radiation pattern, and these coefficients are used as equivalent sources as excitation for the bumper. In this way, the simulations can be completed with significantly less computation time (from 8 to 2 hours) and memory (8 GB per processor to 240 MB per processor) compared to the full-wave simulations. In addition, the effects of secondary surface (e.g. bumper) on the performance of installed radar are also characterized by analyzing the spherical mode coefficients.
