Abstract :
The quality of a radar interferogram can be characterized by wavenumber correlation coefficient. The wavenumber correlation analysis exploits the unique characteristics of the radar interferogram in which in-phase and quadrature-phase terms are highly correlated. One can easily distinguish the signal components from the noise components of the radar interferogram in the wavenumber domain, and consequently this method can be utilized to design a post filter to enhance the interferogram. The wavenumber correlation analysis can also be applied to an amplitude coregistration of a master and slave pair. Test results demonstrate the effectiveness of the proposed approach
