Abstract
This paper explores enhancing WLAN Sensing for MIMO radars by using existing algorithms and protocols already implemented in the standard for communication purposes. By integrating MU-MIMO precoding for beam steering, the spatial awareness of WLAN Sensing is enhanced. The paper includes a comprehensive signal model for Wi-Fi signals as MIMO radars, proposes a precoder for improved sensing, and validates these methods through numerical analysis and experimental results. The research highlights the potential of leveraging communication technologies for advanced radar sensing applications, offering a significant step forward in WLAN sensing capabilities.
