    Abstract: The development and implementation of algorithms for synthetic aperture sonar (SAS) processing requires data with ground truth for validation. In most instances, it is difficult or even impossible to collect real data with sufficiently accurate ground truth. Instead, simulated data is commonly used for this purpose. The requirements of these simulations may range from a simple setup with a few point targets to large models of realistic scenes requiring significant computational resources.\n\nWe previously outlined plans to create an open-source sonar simulation framework to facilitate community-driven development and sharing of simulation techniques. This project, subsequently named the openSTB (open sonar toolboxes) simulator, is now under active development. It is written in Python utilising widely available numerical processing libraries such as NumPy, and has support for high-performance computing (HPC) environments built in. It is designed in a modular structure with each component having a specified interface. A simulation is then created by combining the desired components. As well as the actual simulation methods, this modular structure extends to the loading of inputs and saving of results, allowing the simulator to be integrated with existing data formats and other processing tools. Many common implementations of these components are included, while the defined interface allows users to write their own components to customise the simulations to their needs.\n\nIn this paper we will present the current state of the openSTB simulator. This will include examples of different simulations that can be performed, including simulations utilising an HPC cluster. Future plans for further included components and simulation techniques will also be outlined.
