ENVI® SARscape®

The use of Synthetic Aperture Radar (SAR) data has become increasingly popular in recent years due to its many advantages such as its ability to capture data day or night and see through clouds. However, SAR data can be extremely complex and difficult to work with. ENVI SARscape has made the benefits of SAR data available to professionals across industries for many years. And now it’s gotten even easier!

ENVI SARscape now includes easy-to-use tools for some of the most common SAR processing applications -- extending the benefits of SAR data to more users. These tools, ENVI SARscape Analytics, can be accessed in the ENVI toolbox and ENVI Modeler as well as ArcGIS Pro, and do not require you to be an expert in SAR to run them!

Easily Process and Analyze SAR Data

 

ENVI SARscape allows you to easily process and analyze SAR data and generate products like DEMs or surface deformation maps, while giving you the option to integrate this information with other geospatial products. This unique data analysis capability takes your data from hard-to-interpret numbers, to meaningful, contextual information. Since ENVI SARscape is integrated with ENVI – the premier image processing and analysis solution – you get the added benefit of image analysis tools and SAR processing functionality in one package.

In addition to basic ENVI SARscape Workflows, ENVI SARscape modules enable SAR programmers and scientists to customize processing to meet project requirements.

How Can We Help?

ENVI SARscape Basic

ANALYZE THE INTENSITY

The ENVI SARscape Basic Module includes processing functionality for generating airborne and spaceborne SAR products based on intensity and coherence. This is complemented by a multi-purpose tool, which includes a wide range of functions – from image visualization, to DEM import and interpolation, to cartographic and geodetic transforms.

ACCESSORY MODULES

The Basic Module provides automated pre-processing tools that allow you to quickly and easily prepare your imagery for analysis and visualization. With the Basic Module, the following processing capabilities are supported:

FOCUSING MODULE

The Focusing Module generates complex images (SLC) based on a ‘ω - Ҡ’ frequency domain algorithm.

Support for:
• RS-1/2 SAR
• JERS-1 SAR
• ENVISAT ASAR
• ALOS PALSAR-1 data

GAMMA AND GAUSSIAN FILTER MODULE

The Gamma and Gaussian Filter Module includes a variety of SAR-specific filters, extending the range of filters of the Basic Module. Algorithms for this module are based on gamma and gaussiandistributed scene models. They are particularly efficient in reducing speckle noise while preserving radar reflectivity, textural properties, and spatial resolution, especially in strongly textured SAR images.

Analyze the Phase

INTEFEROMETRY MODULE

This module enables the generation of DEMs (InSAR technique) and surface deformation maps (DInSAR technique). State-of-the-art methodology, applied to data acquired from SAR sensors, generate accurate (up to a vertical resolution of few meters) and detailed surface and terrain height products. The DInSAR technique can detect centimeter-scale displacements over time spans of days to years. The interferometry module is applicable in geophysical monitoring of natural hazards like earthquakes, volcanoes and landslides. It is also useful in structural engineering, particularly for the monitoring of subsidence and structural stability.

The ENVI SARscape Interferometry Module allows you to process Interferometric SAR (2-pass interferometry, InSAR), and Differential Interferometric SAR (2/3/4-pass interferometry, DInSAR) data.

INTERFEROMETRIC STACKING MODULE

The Interferometric Stacking Module integrates point-based (PS-like) and area-based (SBAS-like) techniques for the processing of interferometric stacks. This combined approach enables users to obtain accurate results on both point and distributed targets.

Persistent Scatterers (PS)

Enables users to detect very small displacements (mm scale) and to infer the deformation velocity - and its variation over the time - in particular for very stable (man-made) reflectors that might have independent displacements in respect to the surrounding areas

Small Baseline Subset (SBAS)

A complementary method that exploits Differential Synthetic Aperture Radar interferometry (DIfSAR) techniques to analyze stacks of SAR acquisitions to extract small deformations over large areas, when no point targets are identified but large, correlated displacements occur over natural targets


By combining these two approaches, it is possible to analyze deformation phenomena that affects both extended and localized structures related to natural or man-induced phenomena.
