22 December 1997 Alenia Aerospazio activity on SAR data analysis and information extraction
Author Affiliations +
Since the last few years some works have been presented, in open literature, in the field of SAR data analysis and information extraction. The more the SAR data become of common and routine usage, the more the need for automation of the interpretation and information extraction process increases. Alenia Aerospazio has started, in 1994, a research and development activity for the definition and implementation of a demonstrator of a system for SAR data analysis and automatic target recognition (ATR). The work has proceeded with the identification and selection of the basic tools for SAR image pre-processing. The last step was the definition of the architecture of the ATR system. The considered architecture is based on a two-step process that can be run in sequence or separately. For single image input a rule-based system is considered. Rules for the identification of a predefined set of targets are under implementation. For a temporal series of input images a change-detection approach is considered. This last part of the work is in a preliminary stage: only the algorithm flow and routines identification task has been completed. The possible implementation of the system on a massively parallel computer is considered as a final goal.
