A compact lightweight multipurpose ground-penetrating radar for glaciological applications
We describe a compact lightweight impulse radar for radio-echo sounding of subsurface structures designed specifically for glaciological applications. The radar operates at frequencies between 10 and 75 MHz.

High Frequency radar-derived coastal upwelling index
Abstract. Coastal upwelling has been extensively studied since it plays a critical role in the connectivity between offshore waters and coastal ecosystems, impacting on water quality, fisheries and aquaculture production. Significant efforts have been devoted to the quantification of the intensity, duration and variability of this phenomenon by means ...

Radioglaciological studies on Hurd Peninsula glaciers, Livingston Island, Antarctica [PDF]
We present the results of several radio-echo sounding surveys carried out on Johnsons and Hurd Glaciers, Livingston Island, Antarctica, between the 1999/2000 and 2004/05 austral summer campaigns, which included both radar profiling and common-midpoint ...

Characterisation and synchronisation of a netted software defined radio radar
The present work intends to characterise the combination of two netted software defined radios (SDR) and different radio frequency (RF) front‐ends installed in them, together with a two‐stratum time dissemination and synchronisation system.

OFDM Synthetic Aperture Radar Imaging with Sufficient Cyclic Prefix [PDF]
The existing linear frequency modulated (LFM) (or step frequency) and random noise synthetic aperture radar (SAR) systems may correspond to the frequency hopping (FH) and direct sequence (DS) spread spectrum systems in the past second and third ...
