<summary><strong>📡 Multistatic Sensing (ADR-029/030/031 — Project RuvSense + RuView)</strong> — Multiple ESP32 nodes fuse viewpoints for production-grade pose, tracking, and exotic sensing</summary>
381+
382+
A single WiFi receiver can track people, but has blind spots — limbs behind the torso are invisible, depth is ambiguous, and two people at similar range create overlapping signals. RuvSense solves this by coordinating multiple ESP32 nodes into a **multistatic mesh** where every node acts as both transmitter and receiver, creating N×(N-1) measurement links from N devices.
383+
384+
**What it does in plain terms:**
385+
- 4 ESP32-S3 nodes ($48 total) provide 12 TX-RX measurement links covering 360 degrees
386+
- Each node hops across WiFi channels 1/6/11, tripling effective bandwidth from 20→60 MHz
387+
- Coherence gating rejects noisy frames automatically — no manual tuning, stable for days
388+
- Two-person tracking at 20 Hz with zero identity swaps over 10 minutes
389+
- The room itself becomes a persistent model — the system remembers, predicts, and explains
