SimART is an open-source simulation platform for wireless communication and sensing research, integrating ray-tracing (Sionna RT), 3D visualization (VTK/Qt), drone simulation (AirSim/Unreal Engine), and ROS1 for data streaming. The system provides a desktop GUI (C++/Qt5) that loads 3D scenes from files, OpenStreetMap, or AirSim, and orchestrates real-time or offline radio propagation simulations. It generates channel knowledge maps (CKMs), beam codebooks, and system-level metrics (SINR, BLER, MCS), and supports machine learning-based beam selection via a DeepSense predictor. The platform is designed for researchers prototyping algorithms for UAV communications, beamforming, and link adaptation. While the codebase is functionally rich and modular in parts (scene providers, transform manager, socket workers), it suffers from significant technical drift: it depends on ROS1 (end-of-life), Unreal Engine 4.27 (discontinued), Qt5, and legacy VTK APIs. The C++ code contains large monolithic files (e.g., OsmSceneProvider.cpp ~1100 lines) and duplication between C++ and Python transform logic. There are no automated tests, and many configuration files lack schema validation. Despite these issues, several components (blender scripts, beam codebook utilities, scene provider interface) are well-isolated and could be reused in other projects with minimal adaptation.
