This paper proposes a simple polarimetric angle compensation to make accurate detection of deformed/inclined buildings possible by using quad-pol SAR data. It is expected that by applying the new compensation to the coherency matrix after doing conventional orientation angle compensation (OAC), undesired large surface scattering contribution generated between the inclined sidewall of the building...
In this paper, the results of polarimetric scattering measurement is presented to verify the efficiency of proposed man-made object detection algorithm. The polarimetric angular indices α and β are known to be effective for identification of well-regulated structures. However, the validity for detecting deformed structures is not clear. So the feature of α and β for the squint angle variation of deformed...
This paper proposes a simple algorithm for detecting largely-oriented man-made object by using angular index β, in addition to the conventional angular index a. The angular indices are derived by the eigenvalues/eigenvectors analysis to the rotated coherency matrix of fully polarimetric SAR data. Here the orientation angle compensation (OAC) is carried out to the coherency matrix before doing the...
This paper shows efficacy of an algorithm detecting man-made objects area by measuring and analyzing wave scattering from its models. The algorithm uses the co-polarized correlation coefficient in LR circularization basis and its normalized one, and switch these coefficients for detecting the man-made objects not only normally but also obliquely alignment to the radar illumination direction. For setting...
