Overview of Dolphin-Inspired Sonar
the Echoscopics of Wavar
RENAMING: an "Echoscope" is now a "Toascope"
22 March 2016: A toascope has an array of receivers and computes images
via toas, times-of-arrival, of signal-features at those sensors.
An overview of the sonar-parts of
Dolphin Inspired Sonar.
"Wavar" is used to refer to principles and application of principles that are true of waves in general, be they of sonar or of radar or of some other modality.
"Echoscopics" comes from the title of the first patent "Echo scope." The sensors function in small subsets called "scopions." Each scopion produces from echoes a small "scopic part" of an "image-model" from which images can be computed.
"FBP" = Feature-Based Passive wavar. It computes pictures when the form of a feature of wave is known but the time and place of generation of the wave are not both known.

People whose work has informed or inspired me, with respect to dolphins or sonar, include:
Whitlow Au: "The Sonar of Dolphins"
Randall L Brill "Evidence for an acoustical pathway to the inner ear through the lower jaw for an echolocating dolphin (Tursiops truncatus)"
Paul Nachtigall and Heidy Hardy, as in: "Object representation in the bottlenose dolphin: integration of visual and echoic information."
John Potter and Elizabeth Taylor: "Dolphin sonarómodelling a new receiver," and Potter's article in Scientific American.
M.J. Xitco and H. L. Roitblat: Object recognition through eavesdropping: passive echolocation in bottlenose dolphins.
John Gitt, introduced me to sonar, circa 1993.
Donald Haefner, tutored me in 2011 in seismic imaging in the oil and gas industry.
