> Impulse Calibration Lab

Calibration is vital for obtaining accurate measures with scientific-grade, hydroacoustic echo sounder systems. Calibration establishes sampling system sensitivities and performance characteristics. This knowledge provides accurate estimation of acoustic size and target strength of individually detected fish. HTI’s calibration lab, Impulse, is the only
one of its kind on the West Coast of North America.

The Impulse Calibration Lab is a large floating barge equipped with advanced calibration electronics, rotation apparatus and software.
It’s at the ready to fully calibrate split-beam, dual-beam, single-beam transducers, and echo sounders from 38 kHz to 1 MHz, (with or without FM slide/chirp signals). HTI and the Impulse are located in Seattle on Lake Union and the Lake Washington Ship Canal.
