分析了路面結構層材料介電常數實部和虛部對雷達電磁波反射信號的影響,並得出以下結論: ( 1 )介電常數的實部主要影響雷達反射波的時延,實部越大,時延越長; ( 2 )虛部主要影響除路表反射波幅之外的其它結構層界面的反射波波幅,虛部越大,反射波幅越小; ( 3 )當介質介電常數虛部較大時,忽略虛部將給分析結果帶來明顯的誤差; 3Use personal computers to access campus network services on campus ( through network ports available in classrooms, libraries, student hostels and public areas ) or off campus ( via a vpn connection on broadband or the 56k modem access )
