An Experimental Prototype for Multistatic Asynchronous ISAC

Abstract

We prototype and validate a multistatic millimeter-wave (mmWave) Integrated Sensing And Communication (ISAC) system based on IEEE 802.11ay. Compensation of the clock asynchrony between each transmitter (TX) and receiver (RX) pair is performed using the sole line-of-sight (LoS) wireless signal propagation. As a result, our system provides concurrent target tracking and micro-Doppler (μD) estimation from multiple points of view, paving the way for practical multistatic data fusion. Our results on human movement sensing, complemented with precise, quantitative ground-truth (GT) data, demonstrate the enhanced sensing capabilities of multistatic ISAC, due to the spatial diversity of the RX nodes.
