摘要：In this study, the chaotic binary codes generated by quantum logistic map were adopted to modulate the phase of the orthogonal frequency division multiplexing (OFDM) signal，thus further designing a multicarrier chaotic phase coded radar waveform. Both the ambiguity function and the expression of the pulse compression of this waveform were deduced. In addition, pulse compression is performed on the signal using the segmented fast Fourier transform (FFT) method, which is compared with conventional pulse compression method accordingly. Simulation results suggest that by introducing multicarrier and chaotic phase modulation, the waveform can be improved in terms of complexity, randomness and coding agility. The signal designed in this study exhibits its easy accessibility in terms of signal receiving and processing due to the adopted FFT method, which is proven to be an effective low probability of interception (LPI) stealth radar waveform.
