a brief introduction to the concept and application of smart antennas for
Code Division Multiple Access (CDMA) systems is presented. Following some introductory
remarks in Section 1.1, the basic definition and classification of smart antennas is

Detection of buried landmines by ground penetrating radar (GPR) normally
suffers very strong clutter that will decrease the image quality in
GPR data. Problems are also encountered when imaging steeply dipping
landmines by GPR. To solve these p
