NAVSTAR 10/12 series Introduction
#Sonar - How it works-
The NAVSTAR 10/12CF sonar consists of a transceiver display unit and a dual frequency transducer.
An electronic signal pulse is generated in the transmitter section of the display unit. When coupled to
the transducer, this signal is converted into an ultrasonic signal and is transmitted toward the bottom.
The signal travels through the water until it strikes an object or the bottom. It is reflected back , hits the
transducer surface, and is reconverted into an electronic signal by the transducer. Then it is amplified
in the receiver section, processed in the main logic section, and displayed, as an image on a LCD
screen. (Picture 3)
When your boat travels from point A to point B as shown in Picture 1, the beam of the transducer
installed on your boat shown a cross-sectional view in the water.
Picture 2 indicates a cutaway view under the water when your boat moves from A to point B.
The screen shows the latest scan data at its right position. After the next
scan, the previous data is moved to the left and the latest scan data is
shown at the right position. When your boat moves from point A to point
B, the screen shows the scan data as shown in Picture 3.
