An Analytical Imaging Algorithm for Parallel Invariant SAR

Parallel invariant SAR; Range scaling factor; Chirp-z transform (CZT)

This paper discusses the processing method for parallel invariant SAR, and an analytical imaging algorithm based on GLBF is proposed. The bulk focusing is performed by reference function multiplication (RFM), then the range scaling factor is derived and further corrected by Chirp-z transform (CZT). The algorithm can be applied to wide scene imaging with the derived data blocking rules. The proposed imaging algorithm is verified by simulations.
