Overview MIRAsoft HDR
MIRAsoft HDR is the data acquisition software for the MIRA HDR system. MIRAsoft HDR is used
for collecting new multichannel GPR data and to view already collected data. Post-processing and
interpretation of MIRA HDR are done in other 3D GPR software such as rSlicer and GPR-Slice.
This manual (together with the User Guide for MIRA HDR) explains how to set up the
measurements with the MIRA HDR antenna array, collect data and save it to a suitable format.
During data collection it is also possible to view one radargram and traces from all channels.
The user interface of MIRAsoft HDR is developed to be easy to handle during field work and work
as well on a touch screen, as on a field computer. The workflow is straight forward and consists of
the following steps:
1. Make sure that the MIRA HDR antenna box is on and connected to the data acquisition
platform
2. Create a new project (with name and type) or open an existing project
3. Measurement settings (different acquisition options, channel selection and trigger type)
4. Positioning (GPS and Total Station parameters)
5. Advanced settings (trace position, geometry settings, power settings, GPS settings)
6. Ready to Measure
The following definitions are used in this User Guide:
Sample Instant, digital value of recorded radar signal at one specific time.
Trace The recorded radar signal from one channel at one point, built up over a short
time by a certain number of samples.
Point distance Distance between each trace collected for all individual channels.
Stacks Number of averages for each trace.
Swath One complete profile line including all channels in the array. The coverage
for every swath depends on the individual channel spacing multiplied by the
number of channels.
Tx Abbreviation for a transmitter antenna.
Rx Abbreviation for a receiver antenna.
