Principle of Operation

 

 

The

 Outlook Forward Scanning Sonar uses a proprietary 

and patented phased array acoustic technology first developed 

for marine use by 

Interphase Technologies.  Known as 

“phased array  ultrasound technology”, its capabilities have 

been proven in the military and medical industries for many 

years.  The amazing video images provided by medical 

ultrasound equipment are familiar to most people and clearly 

demonstrate the technology’s ability to show highly defined 

images in a "real time" or "live action" mode.  

Interphase has 

taken this same technology and modified it for use in the 

marine market.   

 

Most present day fish finders/ depth sounders all work on a 

principle developed during W.W. II, called SONAR, where 

acoustic pulses are used to detect the presence and range or 

distance to an underwater object.  During the 1950’s, several 

devices which used sonar principles were developed and 

marketed to fishing and boating enthusiasts  to detect the 

distance to the bottom (depth) and to indicate the presence of 

any intervening submerged objects - such as fish. 

 

An acoustic array is a group of piezoelectric ceramic elements 

that are precisely sized and spaced.  Each element will send 

and receive acoustic pulses,  as when used in more 

conventional single element depth sounders.  However, when 

all elements in the array are sending or receiving acoustic 

energy at the same time, the entire array behaves like a single 

larger element with one important difference: the ability of the 

array to concentrate its acoustic energy in different directions, 

depending on the different “phasing” of the signals applied or 

received by each element.  Depending on the signal phasing of 

the array, acoustic beams can be directed in an almost 

unlimited number of directions.  For example, using an 8 

element phased array transducer, the 

Outlook is capable of 

steering the acoustic beam in any of 60 different directions.  

Conventional fixed-beam technology would require the use of 

60 different elements to duplicate this capability.  The 

resulting transducer would be much too large and costly to be 

of any practical use. 

 

Since the acoustic beam in the phased array is steered 

electronically, requiring no moving parts, it can be quickly and 

reliably scanned and re-scanned over a large area.  When 

displayed, the changing information between subsequent scans 

takes on an almost animated quality - for example, showing 

movement of underwater targets such as fish or rapidly 

changing bottom conditions.
