To date, common acoustic features such as MPEG-7 and Fourier/wavelet transform-based
features have been frequently used for environmental sound classification. However, these …

High‐resolution inverse synthetic aperture radar (ISAR) imaging of ship target has attracted

In this paper we present some similarities and differences of bio-sonar echolocation signals
in water and in the air. The echolocation cues of marine mammals and bats are frequency …

In this paper some digital signal processing algorithms, that are used for describing bats'
echolocation calls of two different species of bats (Myotis daubentoni, Nyctulus noctula) are …

A new technique for the cubic Chirplet decomposition via local polynomial Wigner
distribution (LPWD) is presented. Through introducing the parameter of curvature to the …
