Numerically efficient radar signal processing for automotive radars

Abstract

An automotive radar transceiver system (120, 200) including an antenna array (210) and a processing device (230) for processing radar signals received via the antenna array (210). The processing device (230) is arranged to obtain a complex-valued vector (x) of signal values, where each signal value is indicative of a radar signal received at a corresponding antenna element (220) in the antenna array (210). The processing device (230) is further arranged to generate a covariance matrix (C) from the complex-valued vector (x) of signal values by multiplying the complex-valued vector (x) with its complex conjugate, and the processing device (230) is arranged to perform a QR-decomposition of the covariance matrix (C) to generate a Q-matrix (Q), and to determine one or more angles associated with respective targets based on the QR-decomposition of the covariance matrix (C).
