  • Radar System to Jointly Detect Direction-of-Arrival and Direction-of-Departure Angles in Multipath Scenarios
    Publication number: 20240241243
    Abstract: This document describes techniques and systems to enable a radar system to jointly detect DoA and DoD angles in multipath scenarios. In some examples, an automotive radar system includes one or more processors. The processors obtain electromagnetic (EM) energy reflected by objects and generate, based on the reflected EM energy, a two-dimensional (2D) data matrix. The 2D data matrix has a number of rows corresponding to the number of antenna elements in a transmitter array and a number of columns corresponding to the number of antenna elements in a receiver array. Using the 2D data matrix, the processors can determine DoA estimates and DoD estimates in both monostatic and bistatic reflection scenarios. By comparing the DoA estimates to the DoD estimates, the processors determine angles associated with the objects with improved angular resolution and reduced cost.
