Abstract: Some embodiments of the present disclosure provide for configuring devices to passively identify themselves even while not actively engaged in accessing a network. Upon receipt of a sensing signal, passive device components of a given device form a backscatter signal that is an altered version of the sensing signal. The source of the sensing signal, or an appropriately configured network node, upon receipt of the backscatter, may identify the given device by the nature of the alteration. The source of the sensing signal, or the appropriately configured network node, may then be considered to have gained information on the existence of the given device as well as a general location for the given device. The network may enlist the help of other devices to sense the environment and, by doing so, may ultimately achieve a greater degree of resolution of the sensed environment.

Abstract: Disclosed are methods and systems for a WLAN device operating on DFS channels to calibrate the PRI as well as delays between partial pulses of received radar pulses that are impaired due to channel and filtering effects. The calibrated PRI may approximate the PRI of the transmitted pulses. The calibrated delay between the partial pulses estimates the interval between two partial pulses that originally belong to the same transmitted pulse. Using the calibrated PRI and the calibrated delay between partial pulses, the WLAN device may reconstruct the original pulses from received impaired pulses even when the impaired pulses are delayed and partial pulses of the original pulses. The WLAN device may use the calibrated results to correct the shortened PW and varying PRI of the impaired pulses to restore the partial pulses to their full PW with a relatively uniform PRI, increasing the probability of detecting the radar signals.
