NICOP - GPS-Reflectometry for Target Detection
Abstract
The objective of this work is to characterize the capability of GPS signals of opportunity fordetecting and localizing targets on t"he sea surface. The work stems from the advantagesoffered by GPS-Reflectometry (GPS-R) in terms of spatial and temporal sampling, a""nd lowcost/low power technology, and from the exploitation of GPS-R in a backscatteringconfiguration, to enhance the target return"" with respect to the sea clutter. The proposed studywill provide a proof-of-concept of GPS-R as a new method for target detection,"" through a)the development of a GPS backscattering simulator, which integrates models of sea clutterand backscattered GPS signals"" from targets, and b) the optimization of the receiving systemfor this application, and analysis of which targets are detectable. G"PS-Reflectometry orGPS-R is potentially revolutionary as a means for covert and standoff maritimesituational awareness. Detection" and tracking information from reflected GPS signalscould be provided everywhere and frequently in time, due to the ubiquity of GPS"" ornavigation signals in general. The only requirement is cheap, low-power and light-weightmodified GPS receivers that are easy to" design. The high space-time sampling offered bythis technique could increase dramatically the observations in all those situations" wherethe number of sensors to collect information is still insufficient. This can lead to realtime,continuous and ubiquitous surv"eillance capability on wide field of regards
