比较了空中交通警戒与防撞系统(TCAS)和自动相关监视系统(ADS-B)的监视原理,构建了TCAS/ADS-B组合监视系统,对组合监视系统的监视区域进行了划分。采用当前统计模型的数据融合算法,得到了优化的TCAS局部轨迹估算和优化的ADS-B局部轨迹估算,以及优化的融合轨迹估算。仿真结果显示,最大优化融合位置误差为100 m,证明该组合监视系统可以提高目标飞机轨迹估算的准确度,从而提高TCAS的监视精度。
比較瞭空中交通警戒與防撞繫統(TCAS)和自動相關鑑視繫統(ADS-B)的鑑視原理,構建瞭TCAS/ADS-B組閤鑑視繫統,對組閤鑑視繫統的鑑視區域進行瞭劃分。採用噹前統計模型的數據融閤算法,得到瞭優化的TCAS跼部軌跡估算和優化的ADS-B跼部軌跡估算,以及優化的融閤軌跡估算。倣真結果顯示,最大優化融閤位置誤差為100 m,證明該組閤鑑視繫統可以提高目標飛機軌跡估算的準確度,從而提高TCAS的鑑視精度。

The principle difference between Traffic Alert and Collision Avoidance System(TCAS)and Automatic Dependent Surveillance-Broadcast (ADS-B)surveillance is compared . A TCAS/ADS-B integrated surveillance system based on the current statistical model is built . The surveillance range of the integrated surveillance sys-tem is divided into sub-ranges . Using the data fusion algorithm,the optimal local track of TCAS and ADS-B,as well as the optimal fused track of the integrated system are estimated . The simulation results show that the maxi-mum optimal fused estimated position error is 100 m,which proves that the integrated system can improve track estimates accuracy,so as to improve the surveillance precision of TCAS .
