| Abstract: |
| Objective To master impacts of solar storm on performance of shortwave electronic equipment and corresponding solutions and provide reference for system design. Methods The forms of solar storms were analyzed and influences of solar storm on shortwave beyond visual range radar, short wave communication, etc. were given from ranging coverage, object detection, positioning accuracy et al. Results The ionosphere SID and ionospheric storm could interrupt shortwave communication and narrow shortwave spectrum of communication. Strong ionospheric absorption could decrease the sky-wave over-the-horizon radar range and target location accuracy and electron concentration. The inflated rapid change of the ionosphere affected the over-the-horizon radar detection performance and positioning precision. Negative phase ionospheric storm narrowed the available spectrum of the sky-wave over-the-horizon radar severely. During geomagnetic storms, strong electromagnetic field, mutation of voltage and current may burn electronic equipment for sky-ground wave over-the-horizon radar. Irregular phenomenon of ionosphere had serious influences on over-the-horizon radar. Conclusion The solar storm is both advantageous and disadvantageous to performance of electronic equipment. It should be treated respectively. During system design, it is required to take full consideration on influences of solar storm and take corresponding measures to reduce influences of solar storm when it appears. |
