| Abstract: |
| In order to evaluate the real ability of marine HF groundwave commun
ication system, the technology of antenna modeling is combined with HF ground-w
ave propagation model. Method of moment (MoM) is used to compute the radiation c
haracteristic of shipboard whip antenna. The modeling results of directivity pro
perty and the radiation efficiency as well as the measured VSWR property are in
troduce into HF ground-wave propagation computation formula. The computation res
ult
indicates that there has a best operation frequency band, corresponding differe
nt communication distance, to obtain a stronger signal at reception position. |
