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...
This paper introduces the continuous chaotic frequency modulation signals (CCFMS), which have good autocorrelations and flat frequency spectra. We show that the CCFMS have excellent delay and velocity detection performance. Moreover, the CCFMS require far lower realization costs and can provide flexible parameters adjustment. Simulation results show that the delay resolution of the CCFMS can be improved...
