Chirp sub-bottom profilers have the ability to generate frequency modulated ("chirped") seismic data between 4 and 24 kHz. These systems are designed to be operated from small vessels and are typically used when tight vertical control is needed on near-surface, buried rock or hardpan.
The EdgeTech 3100-P Portable Sub-Bottom Profiling System is a high- resolution wideband Frequency Modulated (FM) subbottom profiler which utilises EdgeTech's proprietary Full Spectrum chirp technology. The system transmits a FM pulse that is linearly swept over a full spectrum frequency range (for example 2-16 kHz for 20 milliseconds).
The acoustic return received at the hydrophones is passed through a pulse compression filter, generating high resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers.
