Simulation tool for space borne traffic data collection

Abstract

Space borne traffic data collection is an important method to complement surface and air borne data. We present a first version of a simulation tool that analyses the feasibility of detection of traffic situation over large areas using radar sensors on satellites and airplanes. With this tool it will be possible to evaluate the information content of traffic data acquired by any given sensor. In this tool, the processes determining traffic data collection with space borne radar sensors are reconstructed. All relevant features for traffic monitoring, starting with the traffic scene followed by the sensor and traffic data extraction and interpretation, are simulated. The simulation tool has a modular structure. Each module is independent and exchangeable and describes one separate part of the traffic remote sensing process. The modular structure of the software guarantees maximum flexibility and portability. Changes in one module do not necessarily require changes in other modules. This tool is suitable for a precise specification and optimization of sensor and satellite parameters for traffic data collection. The results can be applied to future satellite missions.
