Paper Abstract

We demonstrate an algorithm for determining low entropy fully polarimetric synthetic aperture radar (POLSAR) coherence matrices using inverse syntetic aperture radar (ISAR) data. Low entropy information is not accessible using the standard method of averaging pixels. Spatially averaging locally around a SAR pixel is not equivalent to time averaging necessary for low entropy measurement. A low entropy POLSAR measurement indicates the dominance of a single scatterer. Low entropy ocean scattering, primarily from Bragg scattering, will be discussed.
