IMAGING WITH WIRELESS COMMUNICATION SIGNALS

Abstract:

Methods and systems for estimating a distance to an object are described. In an example, a device can receive a reflected signal of a modulated signal being used in a wireless transmission of data. The reflected signal can be a reflection of the modulated signal from at least one object. The device can estimate a distance to the at least one object based on the modulated signal and the reflected signal. Further, the device can use the estimated distance to image a scenery including the at least one object.
