A Homogeneous Ping-Pang Architecture for SAR Real-time Imaging

摘要

Based on the range-Doppler imaging algorithm, a novel homogeneous ping-pang architecture is proposed for synthetic aperture radar (SAR) real time imaging. Different from the normal heterogeneous pipeline architecture, almost the identical design on hardware and software is adopted by the two ping-pang nodes. Therefore, more scalable and efficient performance may be obtained for the proposed design with a balanced computational load, and it is especially suitable to be implemented via the commercial-off-the-shelf (COTS) platform.
