| Description: |
The combination of EHF (Extremely High Frequency) and magnetic field provides an effective method for solving communication “blackout,” but the specific impact of the magnetic field on the modulation mode of EHF signals in the plasma sheath needs further quantitative analysis. The propagation characteristics of the modulated EHF signal in the time-varying magnetized plasma sheath and the selection and limitation of modulation modes by magnetic fields were numerically studied in the present study. The plasma sheath was obtained using the hypersonic hydrodynamic model adopted by previous researchers, and the signal propagation was based on the scattering matrix method. The relevant frequencies are the atmospheric window frequencies. The results show that not only does the signal attenuation but also the signal offset change with time. The influence of the magnetic field intensity, signal polarization mode, carrier frequency, and modulation mode on bit error rate performance is introduced. Through comparison and analysis, it was found that the magnetic field has selectivity and constraint on the modulation mode. |
