• M-Profile ray tracing technique for multipath propagation 

      Kheirallah, H.N.; Rashwan, H.M.; Aboul-Saoud, A.K. ( IET , 1987 , Article)
      A model for the modified refractivity is suggested and used in a new and simple ray tracing approach for multipath propagation. The technique is then used to study the variations in ray path parameters for different path ...
    • Refractivity Statistics For Two Countries In The Middle East 

      Kheirallah, H. N. ( Qatar University , 1989 , Article)
      This paper presents and compares the results of refractive index studies for Mersa Matrouh, Egypt, and Doha, Qatar. Statistics for surface refractivity and refractivity gradients at different heights from the surface are ...
