Abstract
The SAR image statistics regarding intensity, phase, and power spectral density are assessed. The quality factor of interferogram i.e. coherence is discussed and the relation between phase errors and coherence is demonstrated using simulations. The influence of antenna pattern has been studied and supported by simulations. Different phase error reduction methods have been analyzed and compared. A new quality factor for interferometric performance has been proposed that measures the Maximum detectable Frequency of Phase Change (MFPC) in an interferogram.
