Real-time O.S. based radar controller for multi-mode phased array radar system

Modern multi-mode radar systems require efficient control structures and algorithms for the dynamically changing radar missions and environments as well as effective utilization of limited radar resources. In this paper, a real-time operating system (OS) based radar system control technique is presented for a multi-mode search phased array radar system, which is operated in composite target and clutter environments. The proposed radar controller has been designed and implemented with high performance, multiple processors in the real-time operating system environment. The implemented techniques have been evaluated by the real-time operation of the phased array radar system integrated in a van-type test-bed. Depending on the allocated missions and functions, the radar controller efficiently operates by distributing the required loads to the multiple processors interconnected through the dedicated high speed data network. The main hardware structure design is based on the PME68-42, a single board computer of Radstone and the transputer processor of Inmos. The software code is developed using the C-language with VRTXsa of Microtec and VIRTUOSO of ISI. The standard VME bus and transputer link are used for the interfaces between the control processors.
