Lesson 28 — Multi-Spectral Signatures

Radar was never the only sensor watching — the aircraft is still seen, heard, and felt in the infrared. Fuse every band into one picture and detection becomes a union, so the range that decides survivability is R_det = max_b R_b: you are only as quiet as your loudest band.

Multi-Spectral Signatures

The visual and acoustic bands as context, EO/IR as the band that never leaves, and the fusion rule that crowns your loudest band as the one that finds you.

Demo

Loudest Band

Give one aircraft four bands, spend decibels on the wrong one and watch detection sit still — then hit the loudest and watch the limiter jump.
