Este artigo discute a classificação de alvos enterrados no subsolo por polarimetria de radar. O radar de subsuperfície é utilizado para detecção de objetos enterrados abaixo da superfície do solo, como tubulações de gás, cabos e cavidades, ou em operação de exploração arqueológica. Além do eco alvo, o radar subterrâneo recebe vários outros ecos, porque o subsolo é um meio não homogêneo. Portanto, o radar subterrâneo precisa distinguir esses ecos. A fim de aumentar a capacidade de discriminação, primeiro aplicamos o coeficiente de anisotropia de polarização para distinguir ecos de alvos isotrópicos (placa, esfera) versus alvos anisotrópicos (fio, tubo). É simples encontrar o alvo artificial enterrado no subsolo usando o coeficiente de anisotropia de polarização. Em segundo lugar, tentamos classificar os alvos usando a abordagem de assinatura polarimétrica, na qual o estado de polarização característico fornece o ângulo de orientação de um alvo anisotrópico. Todos esses valores contribuem para a classificação de um alvo. Experimentos de campo usando um sistema de radar polarimétrico FM-CW de banda ultralarga (250 MHz a 1 GHz) foram realizados para mostrar a utilidade da polarimetria de radar. Neste artigo, vários resultados de detecção e classificação são demonstrados. É demonstrado que essas técnicas melhoram consideravelmente a capacidade de detecção de alvos enterrados.

Abstract: This paper discusses the classification of targets buried in the underground by radar polarimetry. The subsurface radar is used for the detection of objects buried beneath the ground surface, such as gas pipes, cables and cavities, or in archeological exploration operation. In addition to target echo, the subsurface radar receives various other echoes, because the underground is inhomogeneous medium. Therefore, the subsurface radar needs to distinguish these echoes. In order to enhance the discrimination capability, we first applied the polarization anisotropy coefficient to distinguish echoes from isotropic targets (plate, sphere) versus anisotropic targets (wire, pipe). It is straightforward to find the man-made target buried in the underground using the polarization anisotropy coefficient. Second, we tried to classify targets using the polarimetric signature approach, in which the characteristic polarization state provides the orientation angle of an anisotropic target. All of these values contribute to the classification of a target. Field experiments using an ultra-wideband (250 MHz to 1 GHz) FM-CW polarimetric radar system were carried out to show the usefulness of radar polarimetry. In this paper, several detection and classification results are demonstrated. It is shown that these techniques improve the detection capability of buried target considerably.
