Evaluation of beam-forming algorithms for automotive OFDM signal based radar

In this paper the applicability of beam-forming algorithms in radar systems operating with OFDM signals is investigated. It is shown that beam-forming techniques can be directly applied to the output of an OFDM radar processor in order to calculate two-dimensional radar images in distance and azimuth. With a dedicated system model including a realistic road scenario propagation simulator, the performance of different algorithms in typical automotive radar scenarios is analyzed for 24 GHz ISM applications.
