Many types of radar systems have been applied to the study of a wide range of volcanic features. Fields of application commonly include volcano deformation by interferometric synthetic aperture radar (InSAR), mainly satellite-based (e.g. Froger et al., 2007) but also ground-based like LISA (Casagli et al., 2009), digital elevation model generation using satellite or airborne InSAR measurements,...

Quantitative precipitation estimation and rainfall monitoring based on meteorological data, potentially provides continuous, high-resolution and large-coverage data, are of high practical use: Think of hydrogeological risk management, hydroelectric power, road and tourism. Both conventional long-range radars and rain-gauges suffer from measurement errors and difficulties in precipitation estima...

Radars are extremely useful in homeland security for border management and coastal surveillance systems. Due to the terrain, coastal and vegetation conditions a network of short ranged radars are advantageous over single long range radar. Integrating radars in terms of data acquisition and display remains challenging considering the factors like synchronicity, network failures, and channel band...

Glaciers and ice sheets represent sensitive indicators of climate change being their properties strictly related to the environmental temperature and its fluctuations. Therefore, the interest in studying these components of the Cryosphere has strongly increased in recent years. The need of observations on a global scale has promoted airborne and satellite remote sensing techniques for glaciolog...

Two techniques are described for the calibration of ground-based (GB) circularly polarized (CP) full polarimetric radars. The techniques are based on the point target calibration approach that uses various types of canonical reflectors with different orientations. Specifically, the calibration methods for linearly polarized (LP) radar proposed by Wiesbeck et al. and Gau et al. are selected and ...

We present the capabilities of low-frequency radar systems to sound the subsurface for a site located in south-central Egypt, the Bir Safsaf region. This site was already intensively studied since the SIR-A and SIR-B orbital radars revealed buried paleodrainage channels. Our approach is based on the coupling between two complementary radar techniques: the orbital synthetic aperture radar (SAR) ...

Automotive radars for potential accident reduction and for autonomous cruse control were available in 1999, and 77 GHz long-range radars and 24 GHz short-range radars are developing [1]. 79-GHz shortrange automotive radars have a bandwidth of 4 GHz, a maximum range of 30 m, and a range resolution of 5 cm. Radar reception signals often contain unwanted echoes, called “radar clutter.” Moving targ...

Polarimetric remote sensing has demonstrated utility for improving contrast between man-made targets and complex backgrounds. More specifically, polarimetric signatures of man-made targets can be useful for cueing analysts in widearea search applications. However, taking the target cueing to the next level of identification and tracking may require tasking of other sensing modalities. We presen...
