A computer-implemented method for preemptive obstacle detection and tracking in an environment includes the steps: a) constructing a power-angle measurement profile based on signal power indicators (SPIs) within a time interval, the SPIs including a measured power of each signal received via a reconfigurable intelligent surface (RIS) of a plurality of RISs located within the environment; b) mapping a reduction in the measured power in the power-angle measurement profile to a first RIS associated with a first angular sector of the environment to predict a presence of an obstacle therein; and c) updating a coordination plan associated with the RISs based on feedback to track the obstacle. Steps a)-c) are iteratively repeated to predict a presence of the obstacle in further angular sectors. A predicted trajectory of the obstacle is extrapolated over time based on the predicted presence of the obstacle in the angular sectors.
