Method 01
Multiarray GPR
The IDS GeoRadar Stream DP multi-channel array captures dense subsurface coverage in a single pass. Dual polarisation, EsT, then IQmaps. This page is the instrument and how a pass is run.
Traditional locating marks what an electromagnetic signal can hear. Multiarray GPR images the ground itself. Aus-OMI deploys the Stream DP as the primary intelligence layer: a 30-channel dual-polarised array (19 VV + 11 HH), Equalized scrambled Technology (EsT) for depth and resolution in the same pass, then IQmaps for tomography and interpretation.
Every significant call is tied back to a radar response. A continuous reflection, a classic hyperbola, a pick with chainage and depth — the evidence sits next to the interpretation. That is how a finding becomes defensible.
Indoor, GPS-denied, live construction and transport environments are in scope. Acquisition methods adapt to the site. Spatial accuracy does not.
