| Abstract: |
| The frequency choosing is always the bottleneck for upgrading t
he HF communication capability, and the networking HF communication has put forw
ard higher requirements of suitability and time-effectiveness when choosing the
high quality frequencies.According to the frequency management and using requ
irements of the large regional network of HF communication, the
strategy is proposed that combines the loss model, the Chirp detection data and
the Modem detection data to calculate the area coverage of the frequency.Based on t
he calculation results of the regional center station,the assignment
and dynamic adjustment of the pilot frequency and operational frequency is real
ized,the purpose that high-quality frequency is unifiedly managed and shared is achi
eved, and the performance of the large regional network of emergency HF commun
ication is improved. |
