Nature of acoustic nonlinear radiation stress

Nature-inspired Acoustic Sensor Projects

The following pages describe our nature-inspired, or biomimetic, sonars. The biological features incorporated in our sonars include: 1. Binaural reception for accurate bearing determination. 2. Wide bandwidth pulses for object recognition. 3. Echo-controlled sensor mobility. 4. Separate transmitter and receivers for sensitivity of low-level echoes from close-by objects. 5. Nonlinear signal proc...

Acoustic-gravity nonlinear structures

A catalogue of nonlinear vortex structures associated with acoustic-gravity perturbations in the Earth’s atmosphere is presented. Besides the previously known KelvinStewart cat’s eyes, dipolar and tripolar structures, new solutions having the form of a row of counter-rotating vortices, and several weakly two-dimensional vortex chains are given. The existence conditions for these nonlinear struc...
