abstract obtaining reliable precipitation observations is important for hydrological simulations and weather forecasting. radar data can provide insight in the spatial variation of precipitation and can also detect large areas of rain and estimate rainfall rates. weather radar systems nearly always operate in s-, c- or x-band. since x-band systems require smaller antennas than those at c- or s-...

Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...

This workshop aims to explain and debate how new computing techniques can open opportunities to develop innovative radar processing techniques. GPU computing applied to radar signal generation has shown that it is possible to simulate, in quite real time, a dynamic sea with ships in motion. Concerning target simulation, the use of a dynamic sea surface is a way to simulate realistic motions and...

EarthCARE, a candidate Earth Explorer Core mission of ESA (European Space Agency), aims to improve our knowledge of the impact of clouds and aerosols on the Earth’s radiative budget. If the mission is selected, the satellite will carry two nadir sounding active instruments: a Cloud Profiling Radar (CPR) and a backscatter lidar. In addition, a multispectral cloud-imager and a broadband radiomete...

In this study, a high-gain and dual-polarized Quad Ridged Horn Antenna (QRHA) is proposed designed to be used in Obstacle Penetrating Imaging Radar (OPIR) applications. The quad ridged design developed then optimized by using the antenna simulator software; CST Microwave Studio. parameters including center frequency, frequency bandwidth radiation pattern beam width are considered based on requi...

Rapid damage assessment after natural disasters (e.g. earthquakes, floods) and violent conflicts (e.g. war-related destruction) is crucial for initiating effective emergency response actions. Remote sensing satellites equipped with multispectral and Synthetic Aperture Radar (SAR) imaging sensors can provide vital information due to their ability to map affected areas of interest with high geome...

ground penetrating radar (gpr) and magnetic methods were used at ghasr-e-shirin town in kermanshah province, southwest of iran for detecting a series of large ancient (ca 1500 years) underground cavities (tagh). the area of study is a historical monument which is named as emarat e khosro. radar and total intensity magnetic field measurements have been done on the eastern part of the complex, wh...

purpose: to assess various aspects of integrating a virtual reality (vr) simulator in the training of ophthalmology residents methods: in this qualitative study, some aspects of the vr eyesi simulator as a health technology were assessed. data was collected using a multiple-choice questionnaire and several deep interviews addressed to users and administrators of simulator training. face and con...
