Abstract: A method for measuring a separation distance to a target object using a communication signal includes transmitting from a first device, via a transmitter of the first device, a communication signal including a first bit pattern encoded therein. The method also includes receiving, via a processor on the first device, a copy of the communication signal prior to encoding and receiving, via a receiver of the first device, an echo based on the transmitted communication signal. The received echo is decoded and the method includes identifying, via the processor, the first bit pattern in the copy of the communication signal and identifying, via the processor, the first bit pattern in the decoded echo. Then the method determines, via the processor, a time of flight of the first bit pattern based on identifying the first bit pattern in each of the copy of the transmitted communication signal and in the received echo, and performs, via the processor, an action based on the determined time of flight.

Abstract: A method (e.g., a method for measuring a separation distance to a target object) includes transmitting an electromagnetic first transmitted signal from a transmitting antenna toward a target object that is a separated from the transmitting antenna by a separation distance. The first transmitted signal includes a first transmit pattern representative of a first sequence of digital bits. The method also includes receiving a first echo of the first transmitted signal that is reflected off the target object, converting the first echo into a first digitized echo signal, and comparing a first receive pattern representative of a second sequence of digital bits to the first digitized echo signal to determine a time of flight of the first transmitted signal and the echo.

Abstract: A sensing system includes a first radar sensing assembly and an analysis system. The first radar sensing assembly measures plural distances to a first target location at different times using radar. The analysis system receives the plural distances from the first radar sensing assembly and quantifies movements of a target object at the first target location at the different times by calculating differences in the plural distances measured by the first radar sensing assembly. The analysis system generates one or more first quantified activity level values indicative of the movements of the target object at the first target location using the differences in the plural distances that are calculated.
