为解决近地告警系统测试验证的逼真度和直观性问题, 在对近地告警系统原理和测试需求分析的基础上, 提出了近地告警三维视景飞行仿真测试平台的总体方案, 考虑飞机特征和实时性因素建立逼真的飞行仿真模型, 采用合成视景方式提供三维告警包线的可视化显示, 提出了GPWS功能和性能测试评估方法, 能够为GPWS设备和算法提供全面测试。

In order to improve the fidelity and intuitiveness of the test and verification of the Ground Pro-ximity Warning System (GPWS), an overall technical solution of the test platform based on 3D scene and flight simulation for GPWS is proposed based on deep analysis of the principle and verification requirements of the GPWS.Considering the aircraft characteristics and real-time factors, a realistic flight simulation model is established, and the 3D alarm envelope is visualized by using the synthetic view.The GPWS function and performance test evaluation method is proposed, which can provide a comprehensive test for GPWS equipment and algorithms.
