Unlocking Critical Insights With ENVI® Tools Taiwan sits at the junction of major tectonic plates and regularly experiences powerful earthquakes. Understanding how the ground moves during these events is essential for disaster preparedness, public safety, and building community resilience. But traditional approaches like field... Read More >

Comparing Amplitude and Coherence Time Series With ICEYE US GTR Data and ENVI SARscape

12/3/2025

Large commercial SAR satellite constellations have opened a new era for persistent Earth monitoring, giving analysts the ability to move beyond simple two-image comparisons into robust time series analysis. By acquiring SAR data with near-identical geometry every 24 hours, Ground Track Repeat (GTR) missions minimize geometric decorrelation,... Read More >

Empowering D&I Analysts to Maximize the Value of SAR

12/1/2025

Defense and intelligence (D&I) analysts rely on high-resolution imagery with frequent revisit times to effectively monitor operational areas. While optical imagery is valuable, it faces limitations from cloud cover, smoke, and in some cases, infrequent revisit times. These challenges can hinder timely and accurate data collection and...

NovaSAR-1 is Almost Here – Enhancing Remote Sensing Applications

Cherie Tyrrell Wednesday, September 8, 2021

Synthetic Aperture Radar (SAR) is rapidly becoming a fundamental and critical dataset in geospatial analysis. Unlike many other observational methods, SAR is not limited by illumination or cloud cover, so collection and subsequent analysis can be conducted night or day, and even in inclement weather.

One of the most recent and exciting new SAR instruments is NovaSAR-1, which is a small Synthetic Aperture Radar (SAR) mission. It has been partly funded by the UK Government and its mission partners include the UK Space Agency, Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO), the Indian Space Research Organisation (ISRO), the Republic of the Philippines Department of Science and Technology-Advanced Science and Technology Institute (DOST-ASTI), and Space-Eyes LLC.

Images were captured of the same location by NovaSAR-1, Sentinel-1, and Sentinel-2. (Left) NovaSAR-1 HH acquired June 20; (Middle) Sentinel-2 June 21; (Right) Sentinel-1 June 15.

NovaSAR-1 was launched in 2018 and is close to being operational. The S-band SAR platform provides medium resolution (6 - 30m) data, which is ideal for applications in the following fields:

flood monitoring
agricultural crop assessment
forest monitoring (temperate and rain forest)
land-use mapping
disaster management
maritime applications

Data from Sentinel-1 and 2 and NovaSAR-1 complement each other well. In the image highlighted to the left, one can see the way that the way NovaSAR-1 C-band and Sentinel-1 S-band interact with ground cover can be quite different for an identical agricultural area.

ENVI® SARscape® and ENVI SARscape Analytics can be used to easily process and analyze just about all SAR data like that from NovaSAR-1 and Sentinel-1. Their automated SAR-based analytical workflows can run at-scale to solve problems across a wide range of disciplines including disaster mitigation and response, urban development and land use, agriculture, change detection, and monitoring across land and sea.

Dr. Dipak Paudyal, Managing Director of our exclusive distributor in Australia, APAC Geospatial, has written a blog post that looks at the value of NovaSAR-1 data, how NovaSAR-1 data compares to Sentinel-1 data, and how to perform various analysis with this upcoming data type in ENVI SARscape.

Read through his blog post and see how NovaSAR-1 data and ENVI SARscape can provide measurable information for your geospatial applications!
