Abstract
Implementations disclosed describe techniques and systems for efficient determination and tracking of trajectories of objects in an environment of a wireless device. The disclosed techniques include, among other things, determining multiple sets of sensing values that characterize one or more radio signals received, during a respective sensing event, from an object in an environment of the wireless device. Multiple likelihood vectors may be obtained using the sensing values and characterizing a likelihood that the object is at a certain distance from the wireless device. A likelihood tensor may be generated, based on the likelihood vectors, that characterizes a likelihood that the object is moving along one of a set of trajectories. The likelihood tensor may be used to determine an estimate of the trajectory of the object.
