UK Radar Satellite NovaSAR-1 Launched Successfully

The radar imaging satellite NovaSAR-1, carrying an Airbus S-band synthetic aperture radar (SAR), has been successfully launched on a PSLV launcher from India. The spacecraft was built under the leadership of Surrey Satellite Technology Limited, an Airbus subsidiary. The innovative small satellite will be used to monitor the Earth day and night. SAR instruments can see through clouds to enable uninterrupted imaging of the Earth below, which is key when monitoring changes of features on the ground. NovaSAR-1 is the first SAR spacecraft to be manufactured entirely in the UK and is a technology demonstration mission designed to test the capabilities... (read more)

UK Radar Satellite NovaSAR Returns First Images

The first all-UK NovaSAR radar satellite, developed jointly by Surrey Satellite Technology Ltd and Airbus, has sent back its debut images which feature Sydney Harbour and the Egyptian pyramids. The images are being assessed for use in diverse applications, including crop analysis, flood and forestry mapping, and maritime surveillance. The satellite was launched in September 2018, with the intention of having a constellation of NovaSAR satellites. Such a network would enable repeat images of locations to be acquired more quickly - something that is important if changes detected in a scene require a rapid response. (e.g. reacting to an oil spill).... (read more)

Airbus Introduces Radar-derived Ground Control Points

Airbus has launched its new series of radar-derived Ground Control Points (GCPs), offering high point density and centimetre-level accuracy. Users can extract accurate 3D coordinates from high-resolution stereo radar imagery with the help of an inventive geodesy processor. Radar satellites allow swift imagery collection no matter the location, their imperviousness to darkness and climate conditions mean they can acquire data round the clock. Together with its new automatic geodesy processor, this equates to timely processing and delivery of GCPs. Due to their high accuracy relative to GCPs derived by other means, Airbus GCPs can substitute for in-situ measurements, which can... (read more)

Latest Advances in Ground-probing Radar Technology

In this article, Craig Simmonds presents massive advances in ground-probing radar and discusses the journey of the technology over the past quarter of a century. He particularly highlights the major construction projects where the latest revolutionary high-density array ground-probing radar (HDAGPR) technology has been applied and the extraordinary benefits it has brought to all involved in these projects.  Ground-probing radar technology has seen staggering advances since the Vietnam War when it was used to locate buried tunnel networks.  Although the systems of today are far superior with regards to quality of data and speed of operation, the basic principles have...

Radar Satellites Show Antarctic Ice Loss

More than two decades' worth of observations by five radar satellites show the acceleration of ice loss of 30 glaciers in Western Palmer Land in the southwest Antarctic Peninsula. The study in 'Geophysical Research Letters' combines over 24 years of radar data from satellites including ESA’s Envisat and ERS missions, as well as from the Copernicus Sentinel-1 mission. Radar is particularly suited for monitoring polar regions that are prone to bad weather and long periods of darkness because it can collect information regardless of cloud cover, day or night. Mapping 30 glaciers in the region, the research team found that between... (read more)

900 Year Old Tsunami Uncovered with Ground Penetrating Radar

A group of UC Santa Barbara geologists have used ground penetrating radar (GPR) to search for physical evidence of a large tsunami that pounded the Northern California coast near Crescent City some 900 years ago. They discovered the giant wave removed three to five times more sand than any historical El Niño storm across the Pacific Coast of the United States and estimated how far inland the coast eroded. “We found a very distinct signature in the GPR data that indicated a tsunami and confirmed it with independent records detailing a tsunami in the area 900 years ago,” explained Alexander...

SRI International Demonstrates InSAR with Radar Designed for CubeSat

Researchers from SRI International have successfully demonstrated Interferometric Synthetic Aperture Radar (InSAR) capabilities with a radar developed for CubeSat-based earth science applications. Designed for the power and thermal requirements of the space environment, the low-weight, highly compact sensor has the potential to improve short-term forecasting of geologic hazards and enable more effective management of natural resources. InSAR allows for a radar sensor to take high-precision images of an area of interest, such as a volcano or earthquake zone, and measure the differences in ground deformation across multiple data collection times. For maximum impact, InSAR measurements must be precise to the... (read more)

New Radar System Could Lead to Better Defence Against Avalanches

A new radar-based imaging system with an unprecedented ability to penetrate snow-powder clouds could lead to greater avalanche protection for towns, buildings, roads and railways. Successfully installed and tested in the Swiss Alps last winter, the system produces 3D images that reveal how snow flows deep inside avalanches. This new data will strengthen computer models that are used not only to understand the behaviour of avalanches but also to pinpoint ways of building better defences against them. Funded by the Engineering and Physical Sciences Research Council (EPSRC), the Advanced MIMO Radar Development for Geophysical Imaging Applications system was developed by... (read more)
