Abstract

Abstract: Aiming at the problem of large computational load and long processing time of Synthetic Aperture Radar (SAR), this paper adopts SSMEC DSP to complete the low-squint SAR imaging processing, including range compression, azimuthal FFT, Range Cell Migration Correction (RCMC) and azimuthal compression. Eventually, the effectiveness and high efficiency of SSMEC DSP realizing RDA is verified by the real data imaging, which can process 4096*4096 points of data within 831.2ms to meet the real-time imaging requirements.
