Analysis of SAR imagery using various tech to include SAR & EO Imagery fusion and Metadata exploitation.
The SAR imagery is extremely useful during inclement Weather in Target Areas and at Night when Electro-optical (EO) sensors are rendered unusable. However, SAR imagery is difficult to interpret without EO reference image and extensive interpreter training & experience. Even with availability of both, metadata file containing critical material information remains un-exploited as it requires a domain specialization.
1. SAR and EO imagery may be fused to render SAR imagery more ‘readable’ and in the process features may also be extracted to highlight the changes. The user can define unchanging features such as terrain and major infra as well as standard targets to ‘replace’/ enhance the image and targets therein.
2. Metadata SAR is interpreted at the best like an EO imagery using qualitative associated features of shape, background etc. However, metadata on many occasions contain derivable information about the materials which may be useful for an interpreter. The software tool may readily be trained/ programmed to provide interpretation on these aspects, which otherwise require specialized knowledge of physics and working of SAR.
