FPGA based SPECAN algorithm implementation for ScanSAR imaging

An FPGA based implementation of spectral analysis (SPECAN) algorithm for ScanSAR imaging is given in this paper. In order to meet the requirements of system miniaturization and low power consumption, the whole imaging processing will be divided into several time-division stages and mapped to reusable calculation modules and control logics, an optimized processing structure in FPGA is proposed to integrate all the processing procedure in single FPGA chip. In the verification part, FPGA based processing has been compared with Matlab based off-line processing. The experimental results indicate the validity of the design and engineering applicability of the proposed structure.
