Abstract
Techniques and apparatuses are described that implement a smart-device-based radar system capable of performing angular estimation using machine learning. In particular, a radar systemincludes an angle-estimation modulethat employs machine learning to estimate an angular position of one or more objects (e.g., users). By analyzing an irregular shape of the radar system's spatial response across a wide field of view, the angle-estimation modulecan resolve angular ambiguities that may be present based on the angle to the object or based on a design of the radar systemto correctly identify the angular position of the object. Using machine-learning techniques, the radar systemcan achieve a high probability of detection and a low false-alarm rate for a variety of different antenna element spacings and frequencies.
