Analysis of electromagnetic (or acoustic) multipath propagation inventively focuses upon the transmitter-to-target propagation (transmitted propagation reaching target via both direct pathway and forward scattered pathway) and the target-to-receiver propagation (re-transmitted propagation reaching receiver...http://www.google.com.tw/patents/US7161529?utm_source=gb-gplus-share專利 US7161529 - Dual forward scattering method for modeling multipath propagation
