Underwater object recognition (sonar technology)
The name "sonar" stands for "sound navigation and ranging". What is meant are systems used for detection, locating and navigation under water. The fields of application for such systems range from small individual transmitters for leisure boats, which locate fish or indicate obstacles, to professional systems used in large ships to sound the water depth or locate schools of fish. Piezoceramic transmitters of different geometry and covering a frequency range of 5 kHz to 10 kHz are used in the different systems. There are echo sounder systems which use the same ceramic transmitter to send and receive, but there are also the so-called trailing sonars where the sender and the receiver operate separately from each other over greater distances. So-called transmitter arrays consisting of a number of individual piezoceramic disks which can be controlled individually and electronically with a time delay are assembled for large ships. The beam can thus be deflected electronically.
