Dataset of Secondary Surveillance Radar (SSR) plots

AbstractThis dataset contains plot-level measurements collected from a Secondary Surveillance Radar (SSR) system. Each record includes UTC time, longitude, latitude, altitude, and additional flight-related parameters derived from radar returns. The dataset spans multiple continuous time intervals with sampling rates suitable for trajectory reconstruction and sequential modeling tasks. Unlike processed track-level data, the SSR plot dataset preserves raw detection information, enabling research on multi-target tracking, state estimation, filtering algorithms, and long-term sequence modeling. This resource is intended to support studies in air traffic surveillance, radar signal processing, and the development of advanced machine learning methods for trajectory forecasting and tracking.
