  • Page 25: Additional Processing Gain

    1.4.6 Additional Processing Gain In addition to the resolution improvement, correlation processing achieves a signal processing gain over the background noise by using a broad bandwidth transmission pulse that sweeps out over a range of frequencies instead of trying to operate with one very sharp acoustic peak pulse as is done with CW side scan and sub-bottom sonar systems.

  • Page 90: Equipment Required

    6.3.2 Transmission Verification The 2000-CSS Towfish is different conventional side scan sonars used for many years. The early sonars were driven with a high-powered energy burst similar to hitting a bell with a hammer. The transducers are driven with a smooth rising lower power signal that matches the transducer response. Because of this, there is no pronounced clicking noise emanating from the transducers when they are firing.

    A dark band should appear on the sonar processor screen corresponding to the side rubbed. Data throughput rates on the uplink (vehicle to topside) can be critical in getting smooth data from the towfish. The data throughput rate can be checked using EdgeTech supplied utilities at each end of the link...

    6.0: TROUBLESHOOTING The SockBlast application is used to test network throughput between the towfish and the topside computer. This application is normally kept in C:\EdgeTech\Utilities folder on the topside unit, and D:\EdgeTech\Utilities folder on the towfish. Figure 6-1: SockBlast Window Two copies must be run one on each computer.

    6.3.7.1 Preliminary When the electronics has been removed: 1. Check that all boards are still secured to their mountings. 2. Check the mating of all connectors 3. Check that the terminal board screw connections are tight 4. Check for obvious hot /burn spots by sight and smell. 6.3.7.2 No Sonar Data If the sonar display doesn’t scroll, use the ‘scope sniffing’...

    6.3.8.3 Insulation Resistance Breakdown Insulation breakdown is the most difficult fault to locate. Cable leakage is not necessarily located near the end terminations. However, the area near each termination receives the most abuse and is, therefore, 2000-CSS COMBINED SONAR 0017423_REV_C...
