  • Page 8: Sonar Basics

    SONAR BASICS GENERAL Sonar is the bouncing of a acoustic signal off a target and then measuring the time it takes to return - thus giving distance- and measuring the size or amplitude of the returned signal, thus showing hardness of the target. Since the speed of sound in water is 4800 ft per second it is easy to determine the distance to a target by simply measuring the time it takes to make the round-trip and dividing by two.
  • Page 9: Side Scan Sonar Basics

    SIDE SCAN SONAR BASICS SIDE SCAN SONAR The main features that distinguish side scan sonars from other forms of sonar are: sideways looking, narrow beam, two channels, and towed transducers. Sideways look: Originally, sonars 'looked' straight down and were used to measure bottom depth or locate large objects resting on the bottom.
  • Page 10 Side scans operate by transmitting a short, high energy, narrow width acoustic wave out each side of the fish. This high energy acoustic wave hits directly below the fish first (as shown below) Fish Acoustic Wave 100 m Range Switch Target #1 Target #2 10 m...
  • Page 11 As the fish is towed through the water it sends out an acoustic wave and listens for returned waves. How often it sends out a acoustic wave depends on the Range setting. The figure below shows a top view of a series of 12 waves sent out from a passing fish (arrow).
  • Page 12: Jw Fishers Side Scan Sonar

    JW FISHERS SIDE SCAN SONAR INTRODUCTION Fishers basic Side Scan PC system consists of : • Tow fish with two 100Khz, 1 deg by 40 deg transducers (if SSS-100K). • Tow fish with two 600Khz, 1 deg by 40 deg transducers (if SSS-600K) •...
  • Page 13 Tow Cable: The tow cable consists of three electrical cables inside of a hollow-core polypropylene rope. It is tough, durable, and highly abrasion resistant. Cable is available in 150 to 500' lengths. Sonar Processor: The Sonar Processor provides an interface between the Fish and the computer. It receives signals from the Fish, amplifies them, and sends them to the computer using an integrated PC interface board.
  • Page 14: Jw Fishers Side Scan Sonar Theory Of Operation

    JW FISHERS SIDE SCAN SONAR THEORY OF OPERATION BLOCK DIAGRAM The key to side scan operation is to understand how the side scan works. We will begin with an overall block diagram and then discuss the individual components. Computer Sonar...
  • Page 15 Shadow Shadow Transmit pulse Next transmit pulse 1624 Samples Delay After the transmit pulse, the CPU generates a short delay* (to allow the transducers to settle ) and after the delay, it looks at the output of the TVG circuit, and takes evenly spaced samples of the signal. The spacing between each sample pulse is determined by the Range selected.
  • Page 16 Close to the transducer, is a very broad beam which is the result of side lobes. All side scan transducers have side lobes. Top quality transducers, such as those used in the JW FISHERS Side Scan Sonar, have very short side lobes which extend a very short distance.
  • Page 17 The transducers horizontal beam is 1 degree wide. Right Main Beam (horizontal/top view) 4800 fps To insure complete bottom coverage, out away from the fish, the vertical part of the narrow beam must be very wide. The vertical part of the beam is 40 deg wide. The transducer is tilted (pointed) 10 deg down to insure that the main impact of the beam will sweep across the bottom.
  • Page 18 Some part of the main beam and the secondary component go above the fish. When operating in water depths of 50+ ft, with the fish near the bottom, the upper sound wave does not effect the display. However, with the fish within 20 ft of the surface, the water surface and targets on the surface will effect the display.
  • Page 19 FISH ELECTRONICS The fish contains a underwater housing that contains the electronics to generate the 1000 watt power pulse to each transducer; and preamps to amplify the returning echoes received by the transducers. The amplified signals are then sent to the surface Sonar Processor where they are processed. Wires To Surface Control Box Sonar Processor Transmit Pulse...
  • Page 20 TIME VARIABLE GAIN (TVG) The sonar Processor contains a TVG circuit on the PC board that receives the echo signals from the fish preamplifier boards. The TVG circuit amplifies and makes time variable gain adjustments to the signal to make up for signal losses which occur when the echoes are traveling through the water.
  • Page 21 The signal (second drawing below) feeds the input of the TVG amp. The TVG amp has been adjusted, by the operator, to automatically increase the gain over time. The third drawing below shows the gain increase (called the ramp). Fish Acoustic Wave 100 m Range Switch Target #1...
  • Page 22 Each TVG amplifier has three operator controls. They are located on the top panel of the Sonar Processor. Recommended settings for the TVG controls are provided in the Operation Section of this manual. Final TVG adjustments are made by the operator while the unit is running. The function of these controls is to adjust the amplifiers to compensate for losses that occur when the signal travels through the water.
  • Page 23 Delay Commonly called water column removal. Generally, the fish is towed off the bottom 10 - 15% of the Range setting. If we are looking for a small target, that would require a 25 m (80 ft) Range setting, we would tow the fish 3-4 m (12 ft) off the bottom.
  • Page 24 Computer The system will run on a Laptop, Desktop, or on JW Fishers optional “Splash Proof” computer. The “Splash Proof” is a computer system that is built into a Underwater Kinetics case. It utilizes a 10” Ultra Bright” display which is much easier to read in a open boat.
  • Page 25: Operator Switches And Controls

    OPERATOR SWITCHES AND CONTROLS THE HARDWARE Sonar Processor Box - There are two sets of GAIN controls on the Sonar Processor box. One set is for the right channel (right side transducers on the side scan fish) and the other set for the left channel (the left side transducer on the side scan fish).
  • Page 26 OPERATOR SWITCHES AND CONTROLS (continued) • TOWFISH CONNECTOR - The cable from the towfish is attached to this connector. • GPS INPUT connector - Your GPS plugs into this connector. The Sonar Processor requires a NMEA 0183 input. It may be necessary to select this type of output from a menu in your GPS unit (see the Appendix in the back of this manual for more detail).
  • Page 27 OPERATOR SWITCHES AND CONTROLS (Continued) - THE SOFTWARE The majority of operator controls are located in toolbars on the screen. The number of tools in each toolbar, and therefore the number of toolbars, will depend on the resolution setting on your computer display.
