Standard for the Spatio-temporal Synchronization of a Synthetic Aperture of Distributed Sensors

This standard describes spatio-temporal synchronization techniques that support distributed sensors used in multiple-input multiple-output (MIMO) radar, cellular networks, smart factories, geolocation, power beaming, and channel sounding applications, from frequencies of 1 GHz in the microwave band to 110 GHz in the millimeter wave band. This standard details fundamental hardware requirements necessary for the real-time spatio-temporal synchronization of distributed sensors that collectively form a synthetic aperture. The standard relates hardware specifications to achievable performance limits. Computational approaches defined by the standard jointly estimate the position, orientation, and clock parameters of distributed sensors. These estimates allow temporal and spatial coherence to be established between sensors with separate clocks and thereby create a single jointly coherent aperture. Coherence and geometric information between the distributed sensors can also provide accurate geopositioning capabilities. The standard further describes the typical performance losses caused by imperfect synchronization accuracy.

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.

No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.

No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.

No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.

No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.

No Inactive-Reserved Standards
