Web1 is a chirp, and 2 is the phase variation due to the stepped variety of the carrier frequency of the signal. Thus, the signal processing is implemented by the fol-lowing two steps: (1) the pulse compression of the chirp at each PRT gives the coarse range proﬁles; (2) the inverse dis-crete Fourier transform (IDFT) of the coarse range proﬁle A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph…
