A comprehensive investigation of retrodirective cross-eye jamming.
In his thesis, A comprehensive investigation of retrodirective cross-eye jamming, the promovendus presents the first published mathematical and experimental analysis of the retrodirective implementation of cross-eye jamming. A number of new results were obtained, including the fact that retrodirective cross-eye jamming has no effect on a radar that uses the same antenna beam for transmission and reception, and the fact that it is possible to create an infinite error under certain conditions. The relationship between the tolerances of a retrodirective cross-eye jammer system and the error induced in the radar being jammed were also derived. These results were shown to be applicable to all monopulse radars by providing that a phase-comparison monopulse antenna can be used as a model for any monopulse antenna near boresight - a significant result in its own right.
Development of performance functions for economic performance assessment of process control systems.
In his thesis entitled, Development of performance functions for economic performance assessment of process control systems, the promovendus based his research on the performance functions developed for an electric arc furnace, a grinding mill circuit and a stage of a bleach plant. A comprehensive case study of an economic performance assessment of two controllers of a grinding mill circuit is described using a newly published framework to show the significance of performance functions and how to systematically perform an economic performance exercise. The current practice and guidelines on the control and functional/economic performance assessment of grinding mill circuits are captured using a survey study.
