Abstract
Techniques are provided for utilizing time reversed reference signals for radio frequency (RF) sensing operations. An example method for performing radio frequency sensing operations includes transmitting a radio frequency reference signal, receiving channel information associated with the radio frequency reference signal, generating a time reversed radio frequency sensing signal based at least in part on the channel information, and transmitting the time reversed radio frequency sensing signal.
