Abstract:

INVESTIGATIONS WERE CONTINUED OF SURFACE WAVE ANTENNAS APPLICABLE TO GROUND RADAR APPLICATIONS. The main areas of investigation were 1 the effect of the presence of barrier structures of large extent on far-field radiation patterns, 2 measurements of phase velocity in the near field above barrier structures of large extent, and 3 Interferometer measurements applicable to a height-finding technique. An assessment of the phasediscrimination capability of a two-element interferometer system was made at a scaled frequency in the 800 mc range. Author
