An increasing number of modern applications and services is based on the knowledge of the users actual position. Depending on the application a rough position estimate is sufficient, e. g. services in cellular networks that use the information about

We present a novel reconstruction algorithm of ω-k type which suits for wideband circular synthetic aperture data taken in stripmap mode. The proposed algorithm allows to reconstruct an image on a cylindrical surface. The range trajectory is approxi

In this paper a low-cost concept for the controlled RF plane wave exposure for in vivo experiments is presented. The exposure setup is based on the use of a parabolic reflector to convert the incident spherical wavefront emanating from the primary so

The exposure setup presented is intended for a controlled, long-term and continuous exposition (20 Months, 24 h/day) of a large number of animals (100 rats at minimum) with standard GSM and UMTS signals, at 900 MHz and 1966 MHz, respectively. To obta
