A Low-latency, Low-throughput Graphical Architecture for Multi-sensor Pilotage Displays

摘要

This paper reports on a software architecture designed for multi-sensor pilotage displays. A need existed for a graphical display that was highly flexible and reusable between sensor systems. To that end, we developed a graphical rendering system based on scene graph architecture, which allows nodes to be added and removed, depending on the needs of the sensor and display system. Individual users and organizations can develop and apply their own nodes to this architecture while maintaining compartmentalization of intellectual property. We applied this software architecture to a radar sensor pilotage display for a rotorcraft in a degraded visual environment, based on layered extensions of the ICE / BOSS symbology set, as well as standard MIL-STD-2525 symbology. In this paper, we report the results of the software architecture development effort, and outline the rationale behind the design decisions that were made in the development process.
