Abstract
A method for implementing the wideband ambiguity function(WAF) is proposed. By this method the Doppler compression version of a signal is computed by frequency domain interpolation. A good agreement between calculated 3D-diagram and the theoretical expression is shown. The WAF program implemented on minicomputer allows to calculate various parameters of signal. Its application to studying 50 sonar signals emitted by a bat(Myotis mystacinus) discloses why bat uses differently structured echolocation signals during detection, identification, pursuit and capture of an insect.
