De l’impact stratégique de la disponibilité des ordinateurs (COTS = disponible sur étagère) et de l’open source.
Pervasive Use of Digital COTS Processing:
The globalised market for computing hardware and open source software has seen all recent Russian radar and missile system designs built around COTS computing hardware and more that often open source software, especially the Linux operating system, and C/C++ programming language. This trend encompasses signal processing, track data processing, display graphical interface processing, networking, and command post processing.
The availability of advanced yet commodity high performance computer hardware suitable for embedded applications has removed one of the single greatest technological advantages held by the Western world over the Soviets throughout the Cold War period.
Advanced Digital Signal and Data Processing:
The availability of COTS digital hardware and open source software has been a fundamental enabler for the introduction of a range of advanced processing algorithms and techniques until recently exclusive to Western radar designs.
Non Cooperative Target Recognition (NCTR) techniques based on target return fine structure are now appearing in Russian radar designs.
Space Time Adaptive Processing (STAP) techniques, which adaptively reject surface clutter and chaff, are also now appearing in Russian radar designs.
Track fusion algorithms, which are the basis of the US Navy Cooperative Engagement Capability (CEC) system, are now available in at least one Russian design, the Salyut Poima E.
