A novel model of stochastic chaotic radar waveform with stochastically stepped carrier frequencies is proposed, in which, a nonlinear system generating an unpredictable aperiodic stochastic chaotic signal (SCS) is used to control stepping of carrier frequencies. The stochastic chaotic frequency-modulation (SCFM) signal is used as the baseband noise signal, which is truly random and has a thumbtack ambiguity function (AF). SCS can be used to estimate velocity and for imaging of high-speed targets. Wideband signal is obtained by coherently synthesizing for high-resolution range (HRR) imaging. Finally, numerical simulations show the effectiveness of the proposed signal model and corresponding algorithms.
