Application of Model-Based Design Techniques to the Development of Antenna Control, SDR Waveform, and Radar Systems

Model-Based Design techniques for development of real-time embedded systems have been shown to provide several advantages over traditional methods. These advantages include the early detection and the reduction of defects, the shortening of development time, the facilitation of code reuse (i.e., model reuse), productivity enhancement. This presentation describes a series of projects that have benefited from the application of Model-Based Design. These projects span the fields of wireless communications, antenna control, and radar.

First, an on-the-move satcom antenna control system developed with Simulink Coder and xPC Target is discussed. A case study comparing model-based to traditional FPGA code development is also reviewed, highlighting where productivity enhancements were realized, and how to best adopt these new techniques within existing design teams. In this study the physical layer of a satcom waveform was constructed using both traditional and model-based methods, with quantitative metrics recorded for comparison. Finally, the presentation describes a radar system. An enhancement to BAE's Obstacle Avoidance and Cable Detection System (OACDS) was rapidly prototyped on a mixed DSP/FPGA platform integrated with MathWorks and Xilinx code generation tools. The presentation discusses the toolset features that enabled the rapid development and successful flight testing of this platform.
