Abstract

In this paper, the influence of pulse repetition frequency (PRF) shakiness on bistatic synthetic aperture radar (SAR) imaging is presented. The PRF shakiness error is analyzed from a physical point of view and a mathematical model for this error is introduced. The simulation results match the physical and theoretical analysis well. It is shown that the PRF shakiness error deteriorates the performance of bistatic SAR imaging on azimuth, for it corrupts the phase coherence between echo signals. Particularly, the peak side lobe ratio (PSLR) and integrated side lobe radio (ISLR) increase with the presence of the error
