    • Effect of Changes in Sea-Surface State on Statistical Characteristics of Sea Clutter with X-Band Radar 

      Ishii, Seishiro; Sayama, Syuji; Mizutani, Koichi (Scientific Research Publishing, 2011-07)
      We have made observations of X-band radar sea clutter from the sea surface and sea-surface state in the Uraga Suido Traffic Route, which is used by ships entering and leaving Tokyo Bay, and the nearby Daini Kaiho Sea ...

    • Measurement of Rain Attenuation in Terahertz Wave Range 

      Ishii, Seishiro; Sayama, Syuji; Kamei, Toshihisa (Scientific Research Publishing, 2011-07)
      ain attenuation at 355.2 GHz in the terahertz wave range was measured with our new 355.2 GHz measuring system under rainfall intensities up to 25 mm/hr. Rain attenuation coefficients were also calculated using four ...

    • Rain Attenuation at Terahertz 

      Ishii, S. (Scientific Research Publishing, 2010-10)
      Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a ...
