Abstract: This document describes techniques and systems to enable a radar system to jointly detect Do A 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.

Abstract: A method and apparatus for implementing a method are disclosed. The method includes providing point cloud data to a machine learning algorithm, the point cloud data detected in the vicinity of an autonomous vehicle. The method further includes differentiating, via the machine learning algorithm, in the point cloud, data directly representing a location of a first object and data indirectly representing a location of a second object. The method includes transforming the data indirectly representing the location of the second object into data directly representing the location of the second object and generating corrected point cloud data based on the data directly representing the location of the first object and the data directly representing the location of the second object. The method includes outputting the corrected point cloud data to the autonomous vehicle.

Abstract: [Problem] To calculate the height of a target or the like at low cost while avoiding the impact of waves. [Solution] This radar signal processing device comprises: a shielding length calculation unit (61) which calculates, on the basis of a reception signal received by an antenna that transmits and receives radio waves, a shielding length (L2), which is the horizontal length of a region where a transmission signal transmitted from the antenna is shielded by a shielding object (13) above a reference plane; and a vertical height calculation unit (62) which calculates, on the basis of the shield length and the positional relationship between the shielding object and the antenna, the height (H2) of the shielding object from the reference plane.
