STROBE TEM / IP MEASURING SYSTEM & SOFTWARE

General description

STROBE is an electromagnetic system for Time Domain Electromagnetic (TDEM) and Time Domain Induced Polarization (TDIP) methods. The STROBE system is designed for mining, hydrogeological and environmental investigations. The main components of the STROBE instrumentation:

• The multifunctional receiver with the palmtop type control computer
• The multifunctional transmitter
• The TEM ground transducer (one component ground probe)

Processing and fast-inversion (1D) softwares for TDEM and TDIP methods is also available.
The system was developed in 2000 and has been used in some exploration and research projects: for cupper-nickel exploration, kimberlite pipe prospecting, ground water exploration, in environmental investigations and for laboratory investigation of spectral induced polarization of sedimentary rocks.

Field configurations

One loop, coincident loop, in-loop (ground probe inside the transmitter loop) and large fixed transmitter loop – roving receiver TEM configurations can be realized on the basis of the STROBE system.
Single loop configuration is very convenient and productive one, because one loop is used both as transmitter and receiver device. In coincident loop configuration separate transmitter and receiver loops are used. In-loop configuration is an analog of coincident loop version with ground probe instead of receiver loop. In fixed transmitter – roving receiver configuration large transmitter loop (up to 1 km2 square) is laid out and secondary field is measured with small receiver loop or ground probe inside and outside the large loop. For IP survey all typical arrays are in use (gradient, pole-pole, pole–dipole, dipole-dipole arrays).
