The Application of Spread-Spectrum Communications to REA Tactical Networks and Deployable Underwater Surveillance Systems
Abstract
Emerging concepts for Anti-Submarine Warfare (ASW) and Rapid Environmental Assessment (REA) increasingly rely on communication technology, in order to implement distributed information networks and to exchange information between naval units and military commands ashore. An operational advantage is expected from the efficient networking of a geographically dispersed force thus shifting the focus from single autonomous platforms to an integrated network approach. This study examines the main features of spread-spectrum radio communications, such as gain against noise, interference rejection, anti-jam capability and reduced power spectral density for covert operations. Performance is evaluated in comparison with classical systems. The advantages are quantified by the Processing Gain, proportional to the used bandwidth, and by the bandwidth expansion factor that characterizes the spread spectrum techniques. Bandwidth 1 power trade-off is also addressed. (good for operation on a battery-powered platform). The applicability of such new techniques to REA and ASW activities is evaluated and assessed, in comparison with traditional methods. Both application-specific requirements (such as transmission ranges I data rates) and common requirements(such as reliability, availability and security) are discussed. The impact of state-of-the-art LAN protocols (integrated in COTS SS products) is also discussed. Field tests and accurate analysis of results are recommended for further work. Two different objectives should be pursued: the implementation of a reliable and efficient infrastructure for scientific data acquisition at SACLANTCEN and, at the same time, the demonstration of this concept for future operational applications.
