SCADE Display for the Design of Airborne and Ground-Based Radar Human-Machine Interfaces (HMIs)

摘要

Radar displays have evolved over time from being pure mechanically-driven devices (oscilloscopes) able of displaying raw video showing the operators the detected and amplified target return signal (and the receiver noise) to more evolved, computer-based, interfaces where digital processing allows cleaning up the display by eliminating noise and clutter, and creating precise symbols for each target. These radar interfaces are now becoming more and more interactive, giving radar display operators the ability to not only observe the images, but also interact with them and send commands. This paper introduces the use of model-based tools, such as SCADE Display, for the design of radar Human-Machine Interfaces (HMI), which are becoming intrinsically more complex, due to their interactive nature. It shows how the use of a certified tool like the SCADE Display KCG code generator, complying with the most stringent levels of criticality of the DO-178B and DO-178C standards in aerospace, combined with the reliance upon international standards such as OpenGL for the rendering of HMIs, increases productivity and reduces development and verification costs of either airborne or ground-based radar HMIs.
