Page 33: Basic Theory
Basic theory BASIC THEORY This chapter explains some of the basic theory related to settings, error sources and noise conditions. Settings A sonar will transmit a sound wave into the water around the vessel. When this sound wave hits fish, bottom, or other objects in the water, a part of the sound will be returned as echoes. -
Page 34: Pp Filter
Simrad SH40 PP Filter PP Filter means “Ping-to-Ping Filter”. When this function is activated, the sonar will compare the echoes from one ping with the echoes from the next pings. If an echo is present at the first ping, but then disappears at the next, the sonar will interpret this as noise and reverberation, and remove it. -
Page 35: Tilt
Basic theory Tilt The sonar beam can be tilted vertically in steps of 1 degree, and the chosen tilt is shown on the sonar picture. At 0 degrees tilt you will transmit the sonar beam in parallel with the sea surface, while 90 degrees tilt will direct it straight down. -
Page 36: Cavitation
Simrad SH40 The most common cause of acoustic noise is the propeller and the cavitation caused by its rotation. Other typical noise sources on board your vessels are winches, refrigerating plants, power generators, pumps and cranes. If you experience problems you think are caused by noise, try to find out which system that causes... -
Page 37: Blocking
Basic theory Be aware of that other vessels close to you will also generate reverberation due to the water disturbance caused by the wake, the propellers and the cooling water spill. Blocking The movement of your vessel through the water will often —... -
Page 38: Layers And Deflections
Simrad SH40 Layers and deflections Your sonar operations may also be disturbed by environmental situations that you are unable to control. Two typical conditions are temperature and salinity layers, and deflections caused by increasing or decreasing water temperature. Temperature and salinity layers You may experience that temperature and/or salinity layers exist in the water column. - Page 39 Basic theory On cold days, you may experience the opposite: the cold water will be close to the surface, and the water temperature increases with increasing depth. (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.
