Outdoor ranges are commonly used for accurate RCS measurements of full scale vehicles with or without camouflage. Furthermore, ISAR processing is often used to obtain high quality imagery of the objects. However, these images do not show the vehicles in the environment where they are supposed to operate. This paper describes a ground based SAR system that is used to make accurate measurements on v

We demonstrate the novel application of hard x rays emitted by a laser-produced plasma for differential imaging of elements. An x-ray-emitting laser-produced plasma, obtained by the focusing of radiation from a 10-Hz terawatt laser, is used for biological imaging. The x-ray source can be arranged to yield characteristic x-ray emission lines with photon energies that bridge the K absorption edge of
How do small states approach their security problems? What types of strategic instruments exist for small states, and when and why are certain strategies chosen rather than others? The security of `weak' states is problematic, demanding trade-offs in the decisions made. Using 19th century Swedish security policy as an example, it is argued here that small states, in their pursuit of security and a
Med anledning av att VA-verket i Malmö planerade att lägga om och förnya vatten-ledningsnätet i Östergatan och S:t Gertrudsgatan genomfördes en förundersökning i form av schaktningsövervakning. Övervakningen utfördes av personal från Malmö Kulturmiljö. Exploateringsområdet berörde Malmö äldre stadsområde (RAÄ 20). Östergatan var under medeltiden en del av stadens huvudstråk och benämndes tidigt s
Discussion of the terms "intertext" and "intertextuality" with primary focus on film studies.
We reportwhat is to our knowledge the first production of gain by inner-shell photoionization of ions. Photoionization of 4d electrons from In$+$ ions created a population inversion on a 185-nm In2$+$ transition. This scheme is an isoelectronic scaling of the 442-nm Cd$+$ laser. A single-pass gain constant of 0.9 {\textpm} 0.3 cm{\textminus}1 over a 0.4-cm path was pumped by soft x rays generated
Popular Abstract in Swedish Avhandlingen behandlar problem inom den tillämpade matematiken med speciell inriktning mot elektromagnetisk vågutbredning. Exempel på studerade elektromagnetiska vågor är radiovågor, mikrovågor och ljus. Det speciella som skiljer den här studien från andra liknande studier, är att det medium som vågen passerar genom är ickestationärt, vilket innebär att det ändras underPropagation of transient waves in nonstationary, inhomogeneous, dispersive, stratified media is considered. Waves originating from sources exterior to the scatterer as well as from internal sources are treated. Algorithms are developed and illustrated by computations of wave phenomena in stationary, nonstationary and weakly nonlinear media. In the theoretical part, the underlying hyperbolic equati
