Abstract
An apparatus configured to provide for detection and ranging of a remote object, the apparatus configured to perform the following: based on a first reflected signal comprising a reflection from the remote object of a first frequency varying detection signal that varies in frequency over a first bandwidth; and based on a second reflected signal comprising a reflection from the remote object of a second frequency varying detection signal that varies in frequency over a different second bandwidth; determine a first estimated range based on a first beat frequency signal comprising the first reflected signal mixed with the first frequency varying detection signal; determine a second estimated range based on a second beat frequency signal comprising the second reflected signal mixed with the second frequency varying detection signal; determine a range of the remote object as a function of the first estimated range and the second estimated range.
