N2 - A frequency-domain sparse multifunctional anti-jamming waveform design and processing method is introduced. The anti-jamming waveform is transmitted using wide-to-narrow band transmission technique. By constructing the integrated Hidden Markov Model (HMM) for radar-jammer joint state, the jamming sub-band is predicted, and the corresponding receiving sub-band is determined to effectively mitigate the impact of jamming. Simulation experiments were conducted, demonstrating the pronounced efficacy of the proposed anti-jamming waveform in mitigating jamming effects.
