is presented. The SFNS is similar to the stepped-frequency chirp signal (SFCS), which is
also composed of a burst of subpulses with their carrier frequencies linearly increased or
decreased, but each subpulse is a noise signal instead of a chirp signal. The noise signal of
each subpulse is realized by Logistic mapping, ie it is a kind of chaotic signal or random like
signal. Range compression for SFNS can be as same as that for SFCS when matched …
