This step employs ISFT to achieve the frequency scaling.
Figure 2 shows the flowchart of the ISFT algorithm for OS-BSAR in this paper.
The proposed ISFT algorithm for OS-BSAR is based on the linearization of the 2D spectrum phase factor.
Here based on the residual error analysis, we will give the limitations of the proposed ISFT algorithm.
This is the limitation of the algorithms based on ISFT, Chirp-Scaling and range-Doppler.
