Ultra-wideband polarimetric GPR-array stimulated by pseudo random binary codes

Due to improvements in RF-electronics and digital data throughput, ultra-wideband arrays become of increasing interest in Surface Penetrating Radar applications. This is not only for faster scanning but also because of the ability to gather more information from test objects. Arrays enable to the capture of multi-offset and polarimetric data. Different array structures and scanning procedures are applicable which result in a mixing of synthetic and real array data processing schemes. An adequate antenna array, a stable and fast acquisition electronics as well as a powerful digital system are the prerequisites to implement an UWB array. The article describes some basic issues with regards to a large UWB-array.
