Biosonar Signal Processing Applications

1988
Dolphins have a sophisticated echolocation, or sonar, system that is well adapted to their environment. Given that it serves the animal well, one might ask how the dolphin sonar compares to man made sonars, and if there is anything useful one might apply from knowledge of the dolphin's echolocation system. In this paper we will compare the capabilities

Reconstruction of acoustic scenes in biosonar

The Journal of the Acoustical Society of America, 2018
Biosonar mechanisms are highlighted by comparing acoustically reconstructed scenes derived from generalized methods with the performance of echolocating animals. Bioinspired computations replacing standard methods then offer a path towards understanding the animal’s solutions. Seemingly simple outdoor spaces present flying bats with complex scenes when

Tursiops Biosonar Detection in Noise

1980
Biosonar detection experiments conducted in the ocean are confounded as the range from the animal to the target is increased because added interference, such as fish schools, occlude the “field of view”. This experiment was designed to test deduction performance as a function of noise at a fixed range of 16.5 meters, thus reducing the range variability

Classification of natural landmark with biosonar

The Journal of the Acoustical Society of America, 2004
Echolocating bats can make nocturnal flights in acoustically cluttered environments with the use of echolocation. Their marvelous ability to evaluate natural targets in complete darkness provides us an opportunity to learn target detection, classification, and identification with similar biomimetic platforms.

The acoustic world of bat biosonar

The Journal of the Acoustical Society of America, 2018
Bats and toothed whales (odontocetes) have both independently evolved sophisticated biosonar systems. This raises the question how similar the functional principles of these systems are. Could, for example, insights gained from bats be assumed to hold for odontocetes or vice versa? Could both systems be lumped together as a single source of inspiration

Biosonar Discrimination, Recognition, and Classification

1993
One of the outstanding characteristics of the dolphin sonar system which distinguishes it from any man-made sonar is the ability to make fine distinctions in the features or properties of targets. This ability has amazed and sparked the interest of many involved in the development and use of active sonar systems.

Machine learning challenges in bat biosonar

The Journal of the Acoustical Society of America, 2019
Many bat species thrive in complex natural environments where their biosonar pulses trigger echoes with complex, unpredictable waveforms. In most cases, it remains unknown how the bats obtain sensory information they need from such clutter echoes. Machine learning methods that can extract relationships from large data sets could have a transformative ...

Biosonar inspiration for radar waveform design

The Journal of the Acoustical Society of America, 2019
Bat biosonar offers a natural source for biomimetic design of radar waveforms with inspirations falling into two categories: (1) biosonar principles similar to ones already employed in radar and (2) principles used by bats that operate in ways not yet understood or not yet embraced yet for radar.

Simulating neural responses to biosonar signals

The Journal of the Acoustical Society of America, 2006
The mammalian auditory system is a highly evolved acoustic signal-processing system that performs well even in highly reverberant and cluttered acoustic environments. In echolocating species, the auditory system is even more highly evolved and is generally more important than vision for navigation and foraging.
