Mesh FM Triangulation — Phantom 98.1 MHz Heterodyne Station (Three.js)
Three.js demonstration of RF heterodyne triangulation: two out-of-band carriers (915.0 MHz + 1013.1 MHz) intersect and difference-mix into a 98.1 MHz FM station that exists only at the phase-locked crossing point. Shows the two carrier wavefronts, the beat-envelope waveform panel, the phantom station, a per-target Node-2 phase correction (309.6°) that retunes as the target moves, and a probe grid proving the signal is spatially localized. Runnable Python (mesh_fm_triangulator.py) included.
