Abstract The traditional Range Doppler (RD) algorithm is unable to meet practical
needs owing to the limit of resolution. The order of fractional Fourier Transform (FrFT)
and the length of sampling signals affect SAR imaging performance when FrFT is
applied to RD algorithm. To overcome the above shortcomings, the purpose of this paper
is to propose a high-resolution SAR image algorithm by using the optimal order of FrFT
and the sample length constraints for the range direction. The expression of the optimal
order of SAR range signals via FrFT is deduced in detail. The initial sample More >
