Author:Vogt, DR; Nyareli, TNDate:Jun 2008It is difficult to achieve significant directivity in the radial direction of a borehole radar antenna, because the spacing of antenna elements is typically constrained by the borehole diameter to be considerably less than a wavelength. In ...Read more
Author:Vogt, D; Nyareli, TDate:Jun 2008It is difficult to build directional antennas for borehole radar due to the limited space available in the borehole. Recently published results show, however, that it is possible to obtain directional information even from electrically small ...Read more
