Step 4-A: Field Strength of Isotropic Radiator (Reference Value)
The field strength of the isotropic radiator at the point P is used as a reference. The isotropic radiator is located at Mgeo and has the coordinates (xgeo, ygeo, zgeo).
- Distance d between P and Mgeo (using Pythagoras)
(1) - Computation of power density Siso at point Pwith Pt0 describing the sum of all transmitted antenna powers.
(2) - Computation of the effective electric field strength Eiso at the pixel
P based on the power density Siso and the impedance
of the free space ZF0 = 120 πΩ
