In order to improve the accuracy of subsurface target classification with ground penetrating radar (GPR) systems. it is desired to transmit and receive ultra-wide band pulses with varying combinations of polarization (a technique referred to as polarimetry). The sinuous antenna exhibits such desirable properties as ultra-wide bandwidth. polarization diversity. https://www.markbroyard.com/mega-pick-revlon-colorstay-lip-liner-plum-665-discount-top-super/
