It is known that orientation angle of man-made objects such as aligned buildings can be estimated from an argument value of complex correlation coefficient of circularly polarized synthetic aperture radar(SAR) measurement bases. By making use of such feature, degree-of-order in urban area is defined quantitatively as dispersion of the argument which is called polarization angle(PA) derived from full-polarimetric...
Using a remote-controlled airship (Fig. 1) to simulate a satellite, high altitude platform (HAP) or unmanned aerial vehicle (UAV) is very advantageous when corresponding propagation channels are to be addressed. For example, in case of building penetration loss or vegetation attenuation measurements for high elevation angles, the use of an unmanned airship can dramatically reduce the costs of the...
