Abstract:

In reflective path calculation of shooting and bouncing ray (SBR), reflective tensor is used to imply single and multiple reflected effect and is inferred particularly. Incident direction and polarization after reflection are expressed in dot product of tensor with the original incident direction and polarization. Through analysis of tensor’s calculation, results of different polarizations in monostatic are studied in SBR. The calculating examples show that reflective tensor in SBR is correct and efficient and can be used for analysis of various type of targets.
