Abstract

The correlation time of each Doppler or cross-range resolution cell of a rotating target is derived as the time duration required for the surface roughness elements within the illuminated cell to rotate out of it. Thus, for a fully range-resolved rotating target, each Doppler resolution cell has its associated cross section and correlation time. However, the effective speckle correlation time of the target is weighted towards an effective average over the correlation times of the dominant scattering elements.
