Frequency-Domain Extracted IFFT Method for Synthetic Aperture Radar Imaging with Frequency Coded Waveform

Study of frequency coded synthetic aperture radar was concerned in this paper. A new frequency-domain extracted IFFT approach (FDE-IFFT) to obtain high range resolution profile was proposed, and the mathematical principle of this new method was detailed analyzed. Simulation results and series of radar images using time domain back-projection method were given in the end. All results proved that the FDE-IFFT method has better capability of anti-jamming. It is more effective than conventional IFFT method and can be widely used in frequency coded synthetic aperture radar.
