Multichannel Along-Track Interferometric SAR Systems: Moving Targets Detection and Velocity Estimation
Figure 7
Partition of the dual-band spectrum of a hypothetical SAR interferometric
system. The two bands and are subband
filtered into range
subband (central frequencies ), and the Doppler band into azimuth looks . Each identifies a portion of the 2D
frequency domain not overlapping with the others. Absence of overlapping
guarantees the statistical independence of interferograms.
