ENVI® SAR ESSENTIALS
Easily Tap Into the Power of SAR
Synthetic Aperture Radar (SAR) data offers unique advantages
for defense & intelligence organizations, providing valuable
insights that are not easily obtained with other data sources. The
ability of SAR to penetrate clouds and haze allows for imaging in
all weather conditions, day and night, which is crucial for timesensitive applications. High-resolution SAR data includes detailed
information on surface features, making it ideal for tasks such asdetecting change, analyzing terrain, and monitoring infrastructure.
However, processing and analyzing SAR data can be complex.

ENVI SAR Essentials –What’s Different?

Get to an Answer Fast

ENVI SAR Essentials has changed theparadigm by streamlining SAR processing
and analysis workflows to bring SAR
science to non-SAR experts without theneed for advanced education. It has been
designed to provide users with the tools
they need to create geospatial intelligencefrom SAR data quickly and easily.

With ENVI SAR Essentials you can open
SAR data, visualize it, and perform analysis
in a matter of minutes. Oftentimes, youranalysis doesn’t need to be perfect, but it
does need to be close. Because speed isoften a priority, ENVI SAR Essentials canbe as thorough as you need it to be andgenerate results as accurate as required so
you can get to an answer fast.

Make SAR a Part of Your Geospatial Analysis
Non-experts can tap into ENVI SAR Essentials to create elevation data out of SAR datapairs, conduct various types of change detection unique to SAR, and much more. Those
results can easily be fused with other geospatial data in ENVI to create a more robust andaccurate analysis.
