Abstract
A range sensing apparatus includes a modulator that applies a frequency chirp to a light source, causing a nonlinear variation in a frequency of an outgoing beam towards a target. A detector receives both a portion of the outgoing beam and a reflection of the outgoing beam from the target. A processor, which linearizes the frequency chirp, extracts characteristic signals with and without linearization of the chirps to identify a range and velocity of the target.
