  • Abstract
    An alternative method of SAR signal processing which can be used to simultaneously reduce sidelobes and grating lobes of synthetic wideband waveforms (SWW) is proposed. The method applies the super spatially variant apodisation technique to each subpulse image of the SWW, and then cuts appropriate portions of the expanded spectra of the subpulses to effectively realise a nonlinear SWW with much better characteristics.
