Study of Animal Signals and Neural Processing, with Applications to Advanced Sonar Systems
Abstract
The report begins with a summary of past results, along with some remarks that pertain to newer discoveries. An important new approach to the analysis of animal echolocation behavior is presented in Section 3. The fourth and fifth sections consider likelihood ratio testing and signal to interference maximization as applied to a model of the animal sonar system. The sixth section describes some new results concerning bat signals. The seventh section describes an experiment that is presently being undertaken as a practical test of the theory. The eighth section describes two alternative models of the auditory system. The ninth section deals with the problem of minimizing the volume under the wideband ambiguity function. The mathematical processes involved in animal echolocation are intimately related to the processing of speech by the human auditory system. This relation is discussed and a new method of extracting information from speech is suggested. The Appendix includes some mathematical properties of the signals that have been derived to explain animal echolocation behavior.
