Hull Mount Sub-Bottom Profiler

EdgeTech has designed and developed a variety of different hull mount sub-bottom profiling systems. These systems are all based on EdgeTech’s Full Spectrum® Technology, which provides several distinct advantages over conventional sub-bottom systems, including increased penetration and higher resolution. The tapered waveform spectrum results in images that have virtually constant resolution with depth. Another advantage is the reduction of side lobes in the effective transducer aperture. The wide bandwidth of the sweep frequency has an effect of smearing the side lobes of the transducer. The result is a beam pattern with almost no side lobes.

One of the key features of the EdgeTech systems is the ability to put more than one ping into the water column at the same time. The Full Spectrum (”chirp”) signal processing is used to discriminate which of the pulses has been received. Multiple pulses can be stacked up under user control. Multiple pings maintain an almost constant resolution on the bottom regardless of the water depth

EdgeTech’s sub-bottom profiling systems range in frequency from 500 Hz – 24 kHz. Typical past installations are based on 2x2, 3x3, 4x4 and 5x5 array configurations with varying frequencies depending on the application and vessel requirements.
