摘要： Provided herein is a system and method to determine a heading of a target. The system includes a radar sensor that obtains a snapshot of radar data comprising Doppler velocities and spatial positions of a plurality of detection points of a target, one or more processors, and a memory storing instructions that, when executed by the one or more processors, causes the system to perform conducting a first estimation of a heading of the target based on the spatial positions; conducting a second estimation of the heading of the target based on the Doppler velocities; and obtaining a combined estimation of the heading of the target based on a weighted sum of the first estimation and the second estimation.

摘要： Provided herein is a system and method to fuse data from sensors. The system includes sensors configured to capture data associated with one or more targets, the data including timestamps indicating originating times, one or more processors, and a memory storing instructions that, when executed by the one or more processors, causes the system to perform obtaining, at a filter, transmitted data associated with the one or more targets from the plurality of sensors, from the obtained data, identifying an unsequenced measurement having a timestamp before a second timestamp of a second measurement but obtained at the filter after the second measurement was obtained at the filter, updating a state of the filter according to the unsequenced measurement, based on a nonlinear measurement model and a nonlinear process model.
