Vector network analyzer versus sixport comparison for ground penetrating radar

Abstract

The standard ground penetrating radar (GPR) realized with pulsing technology has its limitations and alternatives exist. Using vector network analyzer (VNA) with time domain transformation is possible, but cost of such implementation is prohibitive. The sixport measurement system can be used as alternative to standard VNA. The comparison of the test cases measured by VNA and sixport are in the paper. The resolution is the same and the dynamic range even greater with the use of sixport system.
