ENVI SARscape - SAR Image Analysis Software
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!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.
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.
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.
