Abstract :
We demonstrate a new computing paradigm for the evolution of the long life-cycle defense system with stringent safety, timing and dependability requirements, namely, the multiple target tracking (MTT) part of a surveillance radar system. We demonstrate the new paradigm´s capability for the support of system upgrades in system software, hardware, and application software while maintaining the existing baseline performance. This new paradigm shares many characteristics with the SEI/CMU Simplex Architecture whose applicability has been demonstrated for a prototypical industrial feedback control application. We present the concepts of our paradigm, lessons learned in applying the paradigm to surveillance radar, and lessons learned implementing the paradigm by integrating standard technologies
