摘要
A method for determining the range of an object includes transmitting successive radar chirps, adding a frequency offset to the successive radar chirps, the frequency offset being a fraction of a range frequency bin, receiving return signals, constructing frequency transforms from each of the return signals, adding each of the frequency transforms together to create a composite frequency transform, and interpolating the range of the object from a frequency peak detected in the composite frequency transform.
