Statistical Characterization of Polarimetric Time-Frequency Coherent Indicator

The polarimetric time-frequency coherent indicator has been proposed and effectively applied, especially for target detection. In this paper, based on the complex Wishart distribution, an associated asymptotic probability for the statistical test of the polarimetric time-frequency coherence is analytically derived. The goodness of fit for the probability density function is tested with Monte Carlo simulated data. It can be observed that the estimated probability density function curve fit well with the theoretical value.
