Abstract

The frequency domain support of wideband synthetic aperture radar data is nonrectangular and exhibits sidelobe artifacts in noncardinal directions. Leakage Energy Minimization (LEM) is an analytic image domain apodization scheme that has been successfully applied to SAR imagery. LEM uses a spatially varying finite impulse response filter, the coefficients of which are selected from a maximum likelihood criterion. LEM can be applied to wideband SAR data, which has an irregularly shaped frequency domain support. The algorithm successfully reduces the sidelobe artifacts without loss of resolution.
