A probe-fed circularly polarized stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of two patches and two substrates. The bottom patch is square-shaped where as the top patch is of triangularshaped. T-shaped slots parallel to the edges of the patches are inserted so that bandwidth can be improved. Enhancement of t...

A method for deriving attenuation time-series on fixed satellite or terrestrial links is described. The method uses meteorological forecast and radar data and permits time coincident derivations for multiple sites that include the inherent spatial correlation properties. The paper describes the approach adopted in the technique and presents preliminary results for two sites in the UK. The time-...

A novel miniaturized design of a multiple slotted antenna is designed and simulation results are presented in this paper. The proposed antenna uses I, Uand inverted L-shaped slots in the radiation patch. The resonance frequencies can be controlled by adjusting the dimensions of the slots. The proposed antenna can meet the demand of WLAN, HIPERLAN/2 and radar applications. The key parameters lik...

This paper addresses the proposal that the number of processed air tracks of a two-tier fusion process can be increased by applying a balanced fusion tree which can balance tracks across local fusion nodes. Every fusion cycle, a fusion process combines duplicate tracks from multiple radars and creates a single integrated air picture (SIAP). The two-tier fusion process divides the fusion process...

A novel phase calibration technique for use with the multiple-frequency Range IMaging (RIM) technique is introduced based on genetic algorithms. The method is used on data collected with the European Incoherent SCATter (EISCAT) VHF radar during a 2002 experiment with the goal of characterizing the vertical structure of Polar Mesosphere Summer Echoes (PMSE) over northern Norway. For typical Dopp...

Traffic scene understanding is an important part of future advanced driver assistance system (ADAS). In this paper we present a probabilistic approach for this problem. We use Hidden Markov Models (HMMs) for modeling the spatiotemporal dependencies of traffic situations. The parameters of the individual models are learned from a data base, generated by a professional driving simulation software...

The data presented in this article are related to the research article entitled "The use of transdermal scopolamine to solve methodological issues raised by gender differences in susceptibility to simulator sickness" (Chaumillon et al., 2017) [1]. In an outstanding first demonstration, Kennedy et al. [2] showed that the Simulator Sickness Questionnaire (SSQ) is an appropriate tool to suit the p...

By mounting the transmitter and receiver of Frequency Modulated Continuous Wave (FMCW) Synthetic Aperture Radar (SAR) system on separate platforms, bistatic FMCW SAR offers more considerable capabilities, reliability and flexibility while maintaining the small size, low cost and agile reaction. The bistatic FMCW SAR raw signal simulator is highly required to quantitatively support the design of...
