摘要： A new methodology for detecting, localizing, tracking, and counting objects. The method for state/space estimation includes arranging in a space a first pair of radio frequency sensors in a network of nodes. The first pair of radio frequency sensors is calibrated to determine a first fading condition associated with the first pair of radio frequency sensors. A signal strength of at least one signal sent between the first pair of nodes is measured. A first likelihood model is determined based on the first fading condition. A first posterior distribution is estimated based on the signal strength of the at least one signal using the first likelihood model for purposes of determining object information within the space.

摘要： Systems and methods are provided for device-free motion detection and presence detection within an area of interest. A plurality of nodes, configured to be arranged around the area of interest, form a wireless network. The plurality of nodes transmit wireless signals as radio waves and receive transmitted wireless signals. The received signal strength (RSS) of the transmitted wireless signals between the plurality of nodes are measured and a value is reported. A computing device receives the reported values for the measured RSS and tracks the reported values over time. The computing device processes the reported values using an aggregate disturbance calculation to detect motion and presence within the area of interest. The computing device may notify notification device of a detected disturbance within the area of interest.
