Page 56: Basic Theory
Simrad SX90 BASIC THEORY This chapter explains some of the basic theory related to settings, error sources and noise conditions. Topics Settings on page 54 Noise and reverberation on page 58 Layers and deflections on page 60 Settings A sonar will transmit a sound wave into the water around the vessel. -
Page 57: What Is Agc
Basic theory When you choose the TVG setting you can either switch it off, or choose a value. The different settings determine how “X log R” much gain the sonar will use as time elapses along the X-axis. A higher value for “X” will make the angle (C) steeper. Default setting on the SX90 sonar is 20 log R What is AGC? -
Page 58: About Beam Widths
Simrad SX90 About beam widths A narrow beam will always reach further than a wide beam. This is because the transmitted power of the sonar is concentrated. Nevertheless, you can easily “miss” a school of fish if you make the beam too narrow. If the range is reduced, it is the common to use a wider beam. -
Page 59: What Is Rcg
Basic theory What is RCG? RCG means “Reverberation Controlled Gain”. This function compare the strength from each echo, and then automatically adjust the range and echo level in the sonar picture. The RCG will remove unwanted echoes from the sea surface and the bottom. -
Page 60: Noise And Reverberation
Simrad SX90 Figure 13 Tilt (CD015005D) The challenge will always be to find a tilt that prevents the fish echoes to be buried in reverberation and bottom echoes. If you use a steep tilt (A) the fish will easily be disguised by the bottom echoes, but a strong RCG setting will help. -
Page 61: Cavitation
Basic theory Cavitation As the propeller blades move through the water, low pressure areas are formed as the water accelerates around and moves past the blades. The faster the blades move, the lower the pressure around it will become. As it reaches vapour pressure, the water vaporizes and forms small bubbles of gas. -
Page 62: Blocking
Simrad SX90 Blocking The movement of your vessel through the water will often — especially in higher sea states — cause air bubbles to be generated, and these bubbles will move along the hull. This is called blocking. In order to prevent this noise from disturbing your sonar operations, it is important to lower the sonar transducer as far down below the hull as possible. -
Page 63: Temperature And Salinity Layers
Basic theory Temperature and salinity layers You may experience that temperature and/or salinity layers exist in the water column. Since the speed of sound in water depends on its temperature and salinity, such layers will cause the sound beam to be reflected. Figure 15 Temperature and salinity layers (CD015005F) If you transmit a sonar beam down towards a temperature... - Page 64 Simrad SX90 Figure 17 Water temperatures on cold days (CD015005H) When the temperature decreases (A) closer to the surface, the sonar beam is deflected up as indicated by the illustration. The school of fish (B) you thought you would see is once again not visible at all, and you will also see a ring of surface echoes.
