Project Description
This work is
concerned with developing the PEER (pulsed electromagnetic energy reflectometry)
concept to provide industry-ready prototypes for non-invasive
measurement of moisture content distribution. Specifically, we arel
developing new techniques for rapid, coincident measurement and analysis
of signals from a transmission line array, investigating the concept
of segmented
waveguides and accurate time markers to further advance
non-invasive techniques, enhancing the LVL sampler and PEER for use with
short (100 mm), high precision probes, and integrating PEER with
microwave tomography (MT) to form a new measurement tool. The work
comprises four main tasks:
1) Fast PEER:
Development of new techniques for (i) rapid, coincident measurement
from a transmission line array and (ii) rapid analysis of the PEER
signals.
2) Segmented TD:
Investigation of
segmented waveguides to provide longitudinal measurement, and the
use of accurate time markers to enhance accuracy and hence further advance
non-invasive techniques.
3) Ultra fast sampler:
Improve the performance of the LVL
sampler and PEER for use with short (100 mm), high precision probes,
and provide new opportunities in ultra high speed sampling of
microwave signals and impulses.
4) PEER-MT: PEER measures on a
centimetre scale to a depth of ~100 mm, and microwave tomography (MT)
resolves a wavelength, typically 100 mm, to a depth of ~1 m. In
collaboration with other research organisations, we aim to integrate the antennas and waveguides to provide a composite map of the moisture and properties
distribution. We also seek integration with spectroscopic
techniques.
