Can I read Low-Frequency Sonar Calibration Sphere on EtoBox?
Low-Frequency Sonar Calibration Sphere by MM MM is a document available to read on EtoBox.
What is Low-Frequency Sonar Calibration Sphere about?
The document discusses the calibration of low-frequency parametric sonar systems, specifically the Simrad TOPAS PS18 Parametric Sub-bottom Profiler, which operates in the 0.5–6 kHz range. It introduces a standard calibration target, a 280-mm-diameter aluminum sphere, optimized for target strength consistency and manageable weight, with target strength varying from -43.4 dB to -20.2 dB across the frequency band. The findings are applicable to both parametric and conventional sonars operating at low kilohertz
