摘要:

针对低空飞行器在复杂地形环境与大机动飞行下的双重遥测跟踪难题,提出了一种提高低空飞行器遥测跟踪弧段的计算模型。加载高分辨率地形高程数据和飞行器轨迹,在球面地球模型中遍历计算地面站跟踪仰角和路径遮蔽角以完成地空通视判断。考虑飞行器三维姿态变化将地面站坐标投影至飞行器弹体坐标系,结合天线方向性图提取各跟踪时刻下的飞行器遥测天线增益,进而实时更新信道参数完成地空遥测链路分析。经多次飞行试验验证,相较于传统算法,模型在运算速度、精确性和稳定性方面表现更好,仿真计算的弧段符合率均值和标准差分别达到105%、7.25%,能应用于地面站布站选址,可有力支撑低空飞行器遥测跟踪弧段全覆盖。

Abstract:

To overcome the difficulty in telemetry tracking of low-altitude aircraft operating in complex terrains with high maneuverability, this paper proposes a computational model to enhance the telemetry tracking arcs of low-altitude aircraft. High-resolution terrain elevation data and aircraft trajectories are integrated to calculate tracking elevation angles and path shielding angles of ground stations by traversing within a spherical Earth model, so as to perform line-of-sight determination between an aircraft and ground stations. Considering the aircraft’s 3D attitude, the ground station coordinates are projected into the aircraft’s body coordinate system. The telemetry antenna gain of the aircraft per tracking epoch is extracted by utilizing the antenna radiation pattern, and channel parameters are then updated in real time for air-ground telemetry link analysis. Multiple flight tests demonstrate that the model outperforms the traditional algorithm in terms of computational speed, accuracy, and stability, and the mean and standard deviation of the arc compliance rate in simulation calculation reach 105% and 7.25%, respectively. The model can be applied to optimize site selection of telemetry ground stations, thereby providing robust support for acquiring complete telemetry tracking arc data of low-altitude aircraft.

Key words: low-altitude aircraft, telemetry tracking arcs, visibility analysis, flight attitude, telemetry link, site selection of stations
