  Abstract: The IEEE Standards Association oversees the development and publication of a wide range of standards. Co-sponsored by the IEEE Signal Processing Society, the Synthetic Aperture Standards Committee is working on standards related to a wide range of synthetic aperture measurements in various fields. The SAS working group is responsible for proposing and developing standards focused on SAS data collection and processing.\n\nThe aim of our first effort is to design a standard file format to facilitate sharing SAS data, whether that is data output by a system and used by the operator or data shared between researchers. This would encompass both the raw data measured by the hydrophones and reconstructed SAS images. The current intention is to use an existing structured binary file format (for example, netCDF) as the container for the data. The standard would then detail how the data is laid out within the container. To make the data usable by the recipient, various pieces of metadata describing how it was collected and processed needs to be available. This metadata would be stored as attributes within the container with the standard giving mandatory and optional metadata for each type of data. The final standard will include demonstration code for reading and writing data, and sample files for users to test their implementations on.\n\nThis presentation will give an overview of the current progress of the working group and the intended roadmap towards a published standard. Worked examples of standardised SAS data files will be presented. After the data sharing standard has been submitted to the IEEE, the working group intends to look at other aspects of SAS that can be the subject of future standards. Some ideas of what these standards could cover and ways to get involved will also be presented.
