Abstract: One or more embodiments of the present disclosure relate to identifying reference portions corresponding to a bounding shape that corresponds to an object. Additionally, the reference portions may include a first reference edge, a second reference edge, and a reference where the first reference edge and the second reference edge intersect. In some embodiments, operations may further include obtaining a first state estimate corresponding to the object and receiving first sensor data corresponding to a first portion of the object, the first sensor data including a first position measurement. Further, operations may further include determining that the first position measurement corresponds to a first reference portion that is one of the reference portions corresponding to the bounding shape and determining a first expected position corresponding to the first portion based at least on the first reference portion.

Abstract: One or more embodiments of the present disclosure relate to obtaining a first state estimate corresponding to an object, the first state estimate including a first velocity vector estimate corresponding to the object. The disclosure may further relate to receiving first sensor data corresponding to a first portion of the object. The embodiments may further include determining a first expected measurement corresponding to the first portion, the first expected measurement including a first expected range rate determined based at least on the first angle measurement and the first velocity vector estimate of the first state estimate. And, determining a second state estimate corresponding to the object, the second state estimate including a second velocity vector estimate corresponding to the object and determined based at least on the first range rate measurement and the first expected range rate.
