we’re able to leverage commonality with battlefield superstars like the Q-53 radar, which has maintained >95% operability during its entire career. Lockheed Martin just delivered our 189th Q-53 system and counting. It is still fielded with the highest confidence for the U.S. Army today. ...
RADARThe article offers information on the Lockheed Martin has been awarded a contract by the U.S. Army to develop the SENTINEL A4 radar system, that provide improved surveillance, detection and classification capabilities against current and emerging aerial threats.Military Technology...
The Sentinel-1 imagery is provided by two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging, enabling them to acquire imagery regardless of the weather. Main applications are for monitoring sea ice, oil spills, marine winds, waves & currents, lan...
The most widely used tool for mapping floods from space is Synthetic Aperture Radar (SAR) equipment carried by satellites, thanks to its ability to collect data 24/7 regardless of weather conditions (Tripathy and Malladi, 2022, Tazmul Islam and Meng, 2022a). SAR is an active system that di...
). The accessibility of freely available SAR data, from sources like the Copernicus Sentinel-1, has significantly boosted the attention and utilization of SAR data for SM monitoring (Balenzano et al., 2021). Nevertheless, the propagation of microwave signals through the SVAT system is inherently...

Sentinel-1 Synthetic Aperture Radar (SAR) data have provided an unprecedented opportunity for crop monitoring due to its high revisit frequency and wide spatial coverage. The dual-pol (VV-VH) Sentinel-1 SAR data are being utilized for the European Common Agricultural Policy (CAP) as well as ...
First, we can consider expanding the feature dimensions by incorporating the spectral dimensions such as by considering long-wave interferometric radar. This can be achieved by integrating the time-dimension reconstruction method and spatial-dimension adaptive interpolation fusion method. In addition, by ...
we preserve the important information while making a single-band raster from a multiband image. Thanks to this, we can put more layers from different dates in one band set. Index layers come from both Sentinel-1 and Sentinel-2, radar vegetation index for Sentinel-1 (RVI4S1) and enhanced ...
