Accuracy evaluation of time domain measurement systems for microwave tomography
Paper in proceeding, 2009
The measurement accuracy of time domain systems
for microwave tomography are evaluated through system level
simulations and compared with that of a network analyzer
based frequency domain system. In the analysis, both a time
domain ultra-wideband (UWB) impulse and multiband system
architectures are considered. It is shown that the measurement
error of the time domain systems mainly comes from analog
to digital (A/D) conversion. For a simple comparison case, the
relative measurement error involved in an estimated object
response signal from the time domain UWB impulse system and
UWB multiband system measurements are around three times
and ten times higher than that from frequency domain system.
