TOPAS PS120
Parametric sub-bottom profiler
TOPAS PS120 is a parametric sub-bottom profiler system for shallow waters.
Concept
The idea of a parametric sub-bottom system is to use higher frequencies to generate the low frequencies that you need for sub-bottom profiling. The parametric conversion is a physical process that happens in the water when two signals with high SL is transmitted, the low frequency differential signal – or the parametric signal is created. A benefit of this principle is that you can do high performance sub-bottom profiling with smaller transducer arrays.
Configurations
TOPAS PS120 comes in 2 different configurations:
PS120 standard
PS120 for rack mounting
Hydrographic Work Station or laptop
