Estimation of Electromagnetic Source Location in Multipath Environment

摘要

A novel method to estimate the source location of electromagnetic (EM) waves in a complicated multipath urban areas is developed. The method is based on the multiple signal classification (MUSIC) algorithm and reciprocity of transmitting and receiving antennas. Results are shown to demonstrate the validity of the proposed method. This method can be applied to searching for the location of the illegal radio station in the urban areas.%近年，無線通信技術は幅広い分野に浸透している．一方，一般無線通信への混信，妨害となっている不法無線局が増加しており，その所在の探査，摘発が大きな課題となっている．本報告では，マルチパス環境において，MUSIC法および3次元の鏡像法による解析に基づいた波源位置推定を行い，その有効性と精度について検討した結果を述べる．
