行防撞。为了解决飞机编队飞行防撞以及与民航飞机TCASⅡ兼容的问题，给出了一种基
于二次雷达(SSR)和ADS-B混合监视的机载编队防撞系统的设计方案。该方案采用了TCAS主动
监视和被动监
视相结合的方法，利用唯一的24位S模式地址来识别和归类目标飞机，将TCAS的监视数据和A
DS-B的监视数据进行数据融合来完成对目标飞机的监视和跟踪。通过将大型编队划分为多个
编队单元的方法，由长机负责保持各个编队单元之间的安全间距。采用收发器将长机产生的
位置保持和碰撞避免的操纵指令通过高频数据链路传送给各个编队单元，各个编队成员按照
操纵指令调整自己飞机的位置，完成对整个编队的位置保持和碰撞避免的集中控制和分散执
行。该方案可以为机载编队防撞系统的设计和实现提供参考和帮助。 |

| Abstract: |
| The Traffic Alert and Collision Avoidance System (TCASⅡ) which is wid
ely used in civil aviation is not suitable for formation flight due to the perfo
rmance limitations of equipment. In order to solve the problem of collision avoi
dance in formation flight and the product compatibility between collision avoida
nce system and TCASⅡ of civil aviation, a design scheme of collision avoidance
system based on Secondary Surveillance Radar(SSR) and ADS-B hybrid surveillance
for formation flight is presented.
A hybrid surveillance method of active TCAS surveillance and passive TCAS survei
llance is used in this design,and the identification and classification of ob
ject airplanes is accomplished by using unique 24 bits mode S address. ADS-B dat
a and TCAS surveillance data are fused based on the data fusion algorithm to mon
itor and track those object airplanes. A large scale formation is split into mul
tiple smaller cells with a cell leader, while a master leader is responsible for
maintaining safe separation between these multiple cells. Steering commands gen
erated by the maser leader to maintain separation and avoid collision are transm
itted to cell leaders by high speed digital communication link through a transce
iver. Individual formation member uses these steering commands to positioning it
self with respect to the leader. So the large scale formation to maintain separa
tion and avoid collision can be realized by using centralized control and decent
ralized execution of multiple aircraft formation cells. The scheme design provid
es some references and assistance for design and produce collision avoidance sys
tem used in formation flight. |
