Two channel equipment for simultaneous acoustic profiling using two sources
Construction and functioning principles of two channel equipment for simultaneous acoustic profiling with two different frequency sources are described. The equipment enables to collect high resolution data for upper part of sediments and reasonable for engineering purposes penetration by single pass of line. Unlike profiling by the use of two independent systems the presented hardware and software package makes possible to synchronize the sources so that to cancel the mutual interference, writes data to common file in single computer, and contains resources for processing of high and low frequency data.
