echolocation
Let an agent explain echolocation in animals, humans and technology, relay biological and physical principles from scientific sources, describe applications, and distinguish echolocation from passive hearing and from vision.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain echolocation in animals, humans and technology, relay biological and physical principles from scientific sources, describe applications, and distinguish echolocation from passive hearing and from vision.
The process of locating objects by emitting sounds or radio waves and interpreting the echoes that return, used biologically by bats, toothed whales and dolphins, some birds and shrews, and by trained blind people through human echolocation, and technologically as sonar in water, radar and radiolocation in air and space, and ground-penetrating radar or georadiolocation for subsurface survey; echolocation reveals distance, direction, size and texture of targets.
What it is for: Locating and characterising objects by echoes.
It can be explain principles; describe animal and human echolocation; describe sonar and radar; distinguish from passive sensing.
Distinguishing features
Active emission
Echo timing and spectrum
Biological and technical forms
Medium dependence
What it looks like
Not a visible object; pulses and returning echoes.
Physical character
bat call frequencies: about 20-200 kHz
dolphin click frequencies: up to about 150 kHz
sound speed in water: about 1500 m/s
How it is recognised
Sensing by emitted signals and echoes
Bat and dolphin echolocation, human echolocation, sonar, radar, ground-penetrating radar
Passive listening emits nothing; lidar uses light; ultrasound imaging is a medical application
