Abstract EN
Novel frequency domain extracted method (FDEM) to obtain high range resolution profile (HRRP) for frequency stepped synthetic aperture radar (SAR) is proposed in this paper, and the mathematical principle and formulas of this new HRRP obtaining idea combined with classical fast Fourier transform (FFT), chirp z transform (CZT), and single point Fourier transform (SPFT) are deduced, analyzed, and compared in detail.
Based on the HRRP data, precision imaging processing is completed using a data block partition based fast factorized back projection algorithm.
Imaging validations are executed and all results proved that the FDEM has a great capability of antijamming.
It is more effective than conventional time domain IFFT method (TDM) and shows a great promise in frequency stepped radar imaging and applications.
