Abstract

Automatic target characterization tools for satellite imagery are the need of the hour, but a large community of users still relies on visual exploration of targets and objects in SAR images. While considering the complex-valued SAR images, just looking at the image may provide incomplete and misleading information, as sometimes two entirely different behaving objects looks quite similar in SAR image. Thus a need was felt to develop tools, to support visual target recognition and analysis. In this paper we present the implementation concerns of multiple subaperture decomposition (MSAD) approach as a software tool for analysis of complex-valued SAR images. MSAD approach exploits the holographic property of complexvalued SAR images at the cost of reduced resolution to understand the scattering behavior of targets on ground. Foremost, this tool is an attempt in direction to generate a temptation to use complex-valued SAR data over detected data for target analysis. This tool has been developed in ENVI-IDL environment.
