Echo Average

 

Signal processing (EAV) suppresses unwanted echoes, making other vessels' echoes distinguishable.

 

What is Echo Average?

 

Furuno's Echo Average is a technology employing image correlation to suppress unnecessary echoes, helping distinguish vessels from unwanted signals.

Technology 2

Echo Average by Furuno is an advanced radar technology designed to enhance the detection and stability of radar targets by averaging the echoes received over a period of time.

 

This technology is integral to Furuno's radar systems, aimed at improving the accuracy and reliability of the radar imagery, particularly in high sea states or other challenging marine environments where radar echoes may be intermittently obscured or distorted.

How does Echo Average work?

 

EAV highlights ships while reducing noise by gradually suppressing irregular echoes

Echo Average, another pioneering radar technology by Furuno


 

With EAV activated, irregular echoes displayed on the screen, like reflections of sea surface waves, are minimized, leaving only stable echoes with stronger colors. EAV technology was initially commercialized by Furuno, who continuously improved it by incorporating regular user feedback. This feedback has been particularly crucial for fishing vessel radars, which need different Echo Average settings for various maritime conditions and objectives. For instance, it led to the development of a new EAV mode that enhances the visibility of fishing floats attached to the fishing line.

Radar waves propagate along Earth's surface, but due to diffraction effect, these waves propagate in a slightly curved manner. The degree of diffraction is determined by many factors including atmosphere density. In general, the diffraction curve allows the wave to go beyond the line-of-sight by about 6%
