Abstract
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.
