Abstract:

Modern military systems must be resistant to electronic countermeasures, have high reliability, and continuously assure high quality functions. Distributed systems are more considered as an interesting possibility, among them Space Distribution, Time or Space-Time Distribution, and Frequency Distribution. When dealing with these techniques, effects of the medium on the coherence of the electromagnetic waves, non-homogeneities, variability and dispersivity of the medium, must be taken into account. A better understanding of the physical phenomena will lead to better technical solutions and will help push back the frontiers of current technical limitations. These techniques apply to high reliability communications, radar systems and satellite systems for radio localization and range finding. For military applications, modern systems largely rely on distributed systems, because of the additional benefits they bring, e.g. counter jamming and performance improvement. Sophisticated signal processing enables the development of these techniques, which provide military systems with the reliability, the hardening and the quality they require. In addition, these systems are able to survive in the battlefield environment. The topics covered include 1 Limitation of the medium, 2 Jamming and noise reduction effects on distributed systems, and 3 Distributed systems.
