Strip chart recorders and other mechanical output devices have been replaced by, for example, digital displays such as LCDs (liquid crystal displays). Since the development of sonar, display technology has also been improved in order to enable better interpretation of sonar data. Such transducers have often been directed in various directions from surfaced or submerged vessels in order to attempt to locate other vessels and/or the seabed for the purposes of navigation and/or target location. Any reflected sound then returns to the transducer to form a return signal that may be interpreted as a surface of an object. For instance, a circular transducer (e.g., a cylindrical shaped crystal with a circular face) typically creates a conical shaped beam with the apex of the cone being located at the source. The transducers are often made using piezoelectric materials.Ī typical transducer produces a beam pattern that emanates as a sound pressure signal from a small source such that the sound energy generates a pressure wave that expands as it moves away from the source.

The transducers can convert electrical energy into sound energy and also convert sound energy (e.g., via detected pressure changes) into an electrical signal, although some transducers may act only as a hydrophone for converting sound energy into an electrical signal without having a transmitting capability. Devices such as transducer elements, or simply transducers, have been developed to produce sound or vibrations at a particular frequency that is transmitted into and through the water and also to detect echo returns from the transmitted sound that return to the transducer after reflecting off an object. In this regard, due to the extreme limits to visibility underwater, sonar is typically the most accurate way for individuals to locate objects underwater. For example, sonar devices may be used to determine depth and bottom topography, detect fish or other waterborne contacts, locate wreckage, etc. Sonar has long been used to detect waterborne or underwater objects. FIELD OF THE INVENTIONĮmbodiments of the present invention relate generally to sonar systems, and more particularly, to providing an ability to display images from both linear and circular downscan transducers. 14, 2009, entitled “Linear And Circular Downscan Imaging Sonar,” both of which are incorporated by reference in their entireties.
