A Real-time SAR Echo Simulator Based on FPGA and Parallel Computing
Abstract: This paper designs
and implements a SAR (Synthetic Aperture Radar) real-time echo simulator based
on multi-FPGA parallel computing. The one-dimensional frequency-domain Fourier
transform algorithm is used in the simulator, and the echo signal model and the
rapid calculation algorithm of impulse response function are introduced. The
pipeline compute structure, multichannel parallel computing and procedure flow
design are the key technologies of the simulator, which are also presented in
details. And finally, the validity and correctness of the SAR echo simulator
are verified through the imaging results of the point-array target and the
nature scene target.
