摘要
针对民用飞机高强度试飞任务中地面测试系统快速部站的挑战,结合复杂试飞环境与试飞实施周期压缩的需求,采用信道建模及改进的图像结构相似性评估方法,实现高精度信道建模与空域环境动态评估。研究了山区、海域等多场景下信道模型的建立,对QPSK调制方式下的误码率及星座图性能进行了仿真分析;将遥感地形与多种图像视觉算法相结合,针对不同机场空域进行角点检测与相似度评估,动态优化遥测收发增益配置。研究结果表明,通过仿真与实测验证可有效提升遥测通信部站效率,缩短地面站建设周期,并为试飞场地选择与设备部署提供依据。
To address the challenge of rapid ground test system deployment for high-intensity civil aircraft flight test missions,and considering the complex flight test environment and the need to compress the flight test implementation cycle,channel modeling and an improved image structural similarity evaluation method are employed to achieve high-precision channel modeling and dynamic airspace environment evaluation.The establishment of channel models in multiple scenarios such as mountainous and maritime areas was studied,and the bit error rate and constellation diagram performance under QPSK modulation were simulated and analyzed.Remote sensing terrain data was combined with various image vision algorithms to perform corner detection and similarity evaluation for different airport airspaces,dynamically optimizing telemetry transceiver gain configuration.The research results indicate that through simulation,actual measurement,and verification,the efficiency of telemetry communication station deployment can be effectively improved,the construction period of ground stations can be shortened,and a basis for flight test site selection and equipment deployment can be provided.
