| 摘要: |
| 广东省航空护林地空通信主要采用手机为通信工具，针对手机通信存在的问题，选用超短波
电台及相关附属设备对航空护林地空通信进行了测试，测试结果表明：飞行真高在 300 m 时， PD—780 手
持机空地之间最远通信距离可达 10 km；空 MD—780G 车载台与地 PD—780 手持机之间双向通信距离最远
可达 30 km，空对地的单向通信最远可达 60 km； MD—780G 车载台空地之间的空地双向通信距离最远可
达 60 km，空对地的单向通信最远距离为 100 km；飞行真高在 600 m 时， PD—780 手持机空地之间最远通
信距离可达 30 km，空 MD—780G 车载台与地 PD—780 手持机之间的空地双向通信距离最远可达 50 km，
空对地的单向通信最远可达 80 km， MD—780G 车载台空地之间的空地双向通信距离最远可达 80 km，空
对地的单向通信最远可达 120 km。超短波的通信距离与飞行高度和电台的功率有关，飞行真高越高、电
台功率越大，则通信距离越大。建立有效的航空护林地空通信保障体系，需要建设一定数量的地面通信
中继站、统一设备型号和呼号频率、超短波电台标配降噪耳机。 |

| Abstract: |
| This paper chooses the ultra-short-wave radio station and the related auxiliary equipment to
test the airspace communication of the aviation forest protection in the light of the existing problems in the
use of mobile communication of air-to-ground communication support techniques of aviation forest protection
in Guangdong province. The test results are as follows: when the flight true height is 300 m, the maximum
air-to-ground communication distance is up to 10 km, airborne MD—780G vehicle and ground PD—780
handheld communication between the air-to-ground two-way communication distance up to 30 km, the one-
way communication to the farthest up to 60 km, MD—780G vehicle space between the air-to-ground two-way
communication distance up to 60 km, air-to-ground one-way communication maximum distance of 100 km; at
the hight of 600 m, the PD—780 handheld space between the maximum distance of up to 30 km, airborne MD—
780G vehicle and ground PD—780 handheld communication between the air-to-ground two-way communication
distance,the maximum distance of up to 50 km, air-to-ground one-way communication up to 80 km, MD—780G
vehicle space-to-ground communication, air-ground two-way communication distance up to 80 km, of the oneway communication up to 120 km. The results showed that the communication distance of ultrashort wave is
related to the flight height and the radio station power. To establish an effective air defense system for aviation
forest protection, it is necessary to build a certain number of terrestrial communication relay stations, unified
equipment model and call frequency, and standard ultrashort wave radio noise reduction. |
