Abstract: Embodiments of the disclosure are drawn to apparatuses, systems, and methods for radio direction finding with an iterative ambiguity resolution algorithm. An antenna array may receive an emitted signal. Two or more phase shifts in the received emitted signal may be determined between two or more pairs of antennas of the antenna array. A set of possible expected phase shifts may be generated from at least two of the measured phase shift. To determine the proper one of the set of expected phase shifts, a set of initial guesses for parameters of a fitting equation may be generated and then each may be optimized to determine optimized fitting parameters. From these optimized fitting parameters a direction of arrival of the emitted signal may be determined.

Abstract: Embodiments of the disclosure are drawn to apparatuses, systems, and methods for radar object classification. A radar classification system may include a number of endpoint units and a base station. Each endpoint unit includes a camera and a radar. The camera may image a scene and the image may be used to establish spatial zones within the scene. The radar may collect point cloud data from one or more objects in the scene. A classifier may determine an identity of the object based on the point cloud data. The base station may collect information such as the identity and location of objects in the scene and relate this information to the spatial zones. For example, objects may be identified as a vehicle, pedestrian, or cycle, and related to zones such as roadway, sidewalk, and crosswalk for the purpose of traffic control.
