  • Abstract
    A new technique for mitigating Doppler aliasing artifacts in synthetic aperture radar (SAR) imagery is demonstrated. The technique uses continuous-wave (CW) transmission of randomised stepped-frequency waveforms. Subsequent processing places Doppler aliasing artifacts in Doppler filter s, effectively removing them from the imagery. Simulated 2-D SAR images illustrate the effectiveness of the technique.
