CARIS INTRODUCES SONAR CORRECTION ALGORITHM
A new sound velocity correction accounting for array separation, developed by CARIS and research from the University of New Brunswick, Canada.
CARIS™ has introduced a new sound velocity correction algorithm to HIPS and SIPS™ that significantly improves results for many mid and deepwater sonars and benefits some shallow water multi-sector systems as well.
The University of New Brunswick, Canada, Ocean Mapping Group did research to develop the new algorithm, which accounts for the separation between transmit and receive arrays when performing ray-tracing. By defining the location of the separate arrays, a more robust estimate of the path of each beam to the seafloor and back can be made, taking into account the physical separation between the arrays and the movement of the vessel through the water between transmit and receive.
The new algorithm was initially developed to work with Kongsberg sonar data, but has been successfully implemented for some other common beam forming multibeam systems. This enhancement is now available for download from the CARIS Online Customer Services website for free for all users of HIPS and SIPS 9.0 with a valid subscription.Edit Module
