Narwhal Sonar Lab — 2D Click-Train Ranging

A top-down sonar-scope simplification of narwhal echolocation: click-train time-of-flight ranging under sea ice, with a real beam pattern and prey-detection range you can tune.

ControlsSliders set click frequency, click-train rate, narwhal cruise speed, sea-ice floe count and ambient noise floor. Click the scope to place a new ice floe, drag to pan, scroll to zoom. Range and beam-width readouts are computed live from real time-of-flight and diffraction formulas rather than scripted.

A top-down, sonar-scope simplification of the same real biosonar physics: click-train time-of-flight ranging and a melon-focused beam pattern steer a narwhal hunting for prey among sea-ice floes you can place yourself.

⚙ Under the hood

Interactive 2D sonar-scope simulation of real narwhal echolocation: click-train time-of-flight ranging (d = c·Δt/2 in cold seawater) and a diffraction-limited melon beam pattern steer a narwhal hunting Arctic cod among sea-ice floes you can place yourself.
