A new calculation method of NuSAR for translational variant bistatic SAR

Processing bistatic SAR image all through numerical calculation is the concept of NuSAR. In this paper, the block scheme of NuSAR is modified to handle the translational variant case. Then a new calculation method of NuSAR is provided, which saves half of the memory compared with the existing calculation method. The provided new NuSAR is practical and can handle the spaceborne-airborne configuration.
