Abstract: Methods and systems are described herein for time synchronization of a distributed sensor array system (“distributed system”). The distributed system includes multiple sensor nodes, which are time-synchronized using a combination of RF signal data and message-based time techniques across multiple communications mechanisms. Time synchronization is implemented both internally between a sensor node's components and over-the-air between different sensor nodes. The distributed system further employs multiple layers of standardized and custom synchronization protocols to build a scalable, potentially zero-hop, time transfer network. The time synchronization accuracies achieved by the time transfer network enable coherency in the distributed system.

Abstract: Methods and systems are described herein for time synchronization of a distributed sensor array system (“distributed system”). The distributed system includes multiple sensor nodes which are time synchronized using status information of a sensor node (e.g., timestamp of an occurrence of an event such as receipt of a request for local timestamp, a receipt of a calibration signal). A timestamp of an occurrence of the event at a sensor node is determined for each of the sensor nodes and a time offset between a timestamp of an occurrence of the event at a reference node of the distributed system and the timestamp of the corresponding sensor node is determined. The distributed system synchronizes each of the sensor nodes based on the time offset of the corresponding sensor node to time align data signals received by the sensor nodes. The time aligned signals are cohered for further processing.

Abstract: Disclosed are systems, methods, and computer programs for determining a range to a target. A system can include a first receiver configured for receiving a first signal from the target and a second receiver configured for receiving a second signal from the target, the second receiver time-synchronized with the first receiver. A programmable processor can determine a range to the target based on arrival times of the first signal at the first receiver and the second signal at the second receiver.

Abstract: Digital model and digital twin generation using generative transformer networks and large language models is described. A digital twin generator is configured to generate a digital twin of a physical system useable for electronic testing with simulated real world conditions in a digital environment. Real world objects are represented accurately in a virtual world digital environment. The digital environment can be updated based on real world conditions. The present systems and methods are configured to enable more accurate and realistic simulation with the real world objects and/or physical systems in the real world conditions compared to prior systems.
