DISCOVER Side Scan Sub-Bottom Profiler Full Spectrum Electronics Dynamically Focused Side Scan Sonar The EdgeTech 2200S Sonar System is designed for the constraints of a small one-man portable AUV. This includes careful attention to weight, size, and power consumption. A 2200-S system consists of drop in payload module that contains the sonar electronics, a built in sub-bottom profiler transmitter and side scan sonar arrays with integrated sub-bottom profiler hydrophones. A software package for display and printing of the data "DISCOVER" • Side Scan Sonar Dual Frequency or 850 kHz CHIRP Dynamic Focus Sub-Bottom Profiler 4-24 kHz CHIRP Completely autonomous operation Controllable from AUV or acoustic link Less Than 30 watts power consumption Very low in-water weight Topside Display Processor Software Geo-hazard surveys Geological/geophysical surveys Buried pipeline and cable location Route Surveys Archeological surveys

In some cases the electronics are collocated with the AUV electronics, in other cases they reside in their own pressure housing A large capacity hard drive is used to store sonar data or the data can be stored by the AUV mission controller. The average data flow is dependent on the sampling frequency, on the data window size, on the ping rate of the sub-bottom profiler, and on the range scale setting of the side scan sonar. Careful attention has been paid to keeping the power consumption low for the 2200-S. The amplifiers are turned off between transmissions. The amplifier power output can be...

By utilizing longer arrays comprised of multiple, individually accessible elements, dynamic aperture techniques can overcome this limitation by changing the length and shape of the array during the receive cycle. This provides an along track beam width substantially less than the physical array length. The full array length can then be exploited at long ranges to provide extremely small beam angles for superior long-range resolution. It also changes the shape of the array from a flat plane to one that is curved and focused, in time, over the sonar swath. Sub-Bottom Profiler The 2200-S is a 4-24...
