Abstract :
Radar receivers use low sidelobe matched filtering techniques to separate closely spaced targets. Ideally, low sidelobes can be achieved through either waveform selection or through spectral weighting of the matched filter. In practice, however, the minimum achievable sidelobe levels are determined by the presence of waveform distortion. Such distortion can be unintentional (e.g., as the result of hardware errors in the radar´s transmitter or receiver) or intentional. This paper presents several non-iterative adaptive processing techniques for canceling coherent waveform distortion. Moreover, these techniques also potentially super-resolve closely spaced targets
