- Abstract:
- A quick aeeurate algorithm for relleetion points and diflraclion points in hybrid paths, as a ray-trae.ing technique, was put forward, for foreeasting station surrounding environment radiation field intensity. Witha general formula for mirror image points and image lines, an algorithm for rellection points in multihop pathswas presented. An oplimization formula for diflraction points in multiple diffraetion path algorithm was intro.duced. By proper transformation between relleetion and diflraetion in hybrid paths,the algorihm which trans.form hybrid paths into diffraction paths was implemented. Finally, the proposed algorithm was applied to im.prove the z-buffer algorithm , the ray propagation path was tracked and field strength was ealeulated in the sur.rounding environment around a communieation base station. The numerieal results from the algorithm are ingood agreement with the measured values.
