Models of Spatial Information Processing in Biosonar Systems and Methods Suggested to Validate Them

Abstract

The objective of this symposium is to review the efforts and results in the research on behavior, neurophysiology, ecology, signal processing and electronics engineering with respect to echolocation since the NATO conference on “Animal Sonar Systems — Biology and Bionics” held at Frascati in 1966. I think the Organizing Committee has made a very good decision by choosing 1979 for the year of this symposium. We can now commemorate the 250th anniversary of the man who first described an animal sonar system, that of a bat, the Italian Abbot Lazzaro Spalanzani, who was born on July 12, 1729, at Scandiano in the province of Modena.
