Page 19: Overview
The system generates high-resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers and provides excellent penetration in various bottom types. The EdgeTech 3400 comes in a dual 2-16 kHz transducer configuration. The towfish is configured with new PVDF receiver arrays segmented for standard sub-bottom profiling operations or a unique “pipeliner”... -
Page 20: Advantages Of Full Spectrum Chirp Technology
All these advantages are discussed in detail below. Separate Acoustic Projectors and Receivers The 3400 Sub-Bottom Profiling System uses acoustic projectors and receivers mounted in a towed vehicle to transmit and receive acoustic FM pulse signals. The projectors are wideband piston-type transducers, and the receivers are hydrophone arrays composed of polyvinylidene difluoride (PVDF) hydrophones. - Page 21 Additional Processing Gain Edgetech CHIRP technology achieves a signal processing gain over the background noise. This gain is approximately ten times the log of the time-bandwidth product. This improvement is due to the signal having a time duration longer than the inverse of the bandwidth, thus increasing signal energy without increasing the power of the outgoing pulse.

Page 27: Surface Echo Attenuation
1.1.7 Pulse Library Tailored for Most Survey Applications The 3400 pulse library includes both FM and BOOST pulses to collect the best datasets on a variety of seafloors. BOOST pulses emphasize the low end of the bandwidth that should exhibit better performance in deeper water than standard FM pulses. -
