Incoming wave tracking method and incoming wave tracking program

摘要

PPROBLEM TO BE SOLVED: To provide a method for tracking an incoming wave and a program for tracking the incoming wave automatically tracking the incoming wave from vast measurement data using the measured receiving position and the incoming direction of a radio wave. PSOLUTION: The method for tracking the incoming wave includes: a step of extracting a ray satisfying a first condition in which the difference value ¾α-β¾ between the incoming direction data α at a first receiving position and the incoming direction data β at a second receiving position juxtaposing the first receiving position is not more than a predetermined threshold value; a step of obtaining the incoming direction slope GSB¾α-β¾/SBfrom the incoming direction α and the incoming direction β for the ray whose difference value ¾α-β¾ is not more than the predetermined threshold value; a step of obtaining the incoming direction slope GSB¾β-γ¾/SBfrom the incoming direction γ at a third receiving position juxtaposing the second receiving position and the incoming direction data β as to the ray; and a step of extracting a ray satisfying the second condition in which the difference value ¾GSB¾α-β¾/SB-GSB¾β-γ¾/SB¾ between the slope GSB¾α-β¾/SBand the slope GSB¾β-γ¾/SBto obtain the ray as the incoming wave.
