摘要: 利用流体力学原理及三角谐波函数,建立简单实时的典型强切变风场仿真模型。以机载X波段相控阵天气雷达参数性能和观测方式为依据,给出雷达水平扇扫和垂直扫描下的风场径向速度仿真数据通过分析仿真数据,指出了机载天气雷达在不同飞行高度上探测强切变风场的特征。利用一次强飑线天气的实际雷达观测资料对比分析了强切变风场仿真数据的可信度。强切变风场的仿真模型数据可作为机载雷达回波信号仿真实验中的相位参数模拟数据,仿真实验结果还可为后续的实际飞行观测提供理论分析和方法依据。

Abstract: The fluid mechanics principle and the triangle harmonic function were used to establish a simple and high real-time typical strong wind-shear field model. The simulation data of wind field velocity in horizontal fan-shaped scanning mode and vertical scanning mode based on the parameter and detecting mode of airborne phase array weather radar was proposed. The different characteristics of strong wind shear detected by airborne weather radar on the different altitude were proposed through simulation data analysis. The simulation data credibility of strong wind shear field was analized based on weather radar velocity of a strong squall line process. The wind field model data could apply to the phase parameter simulation in the airborne radar signal processing. The analysis result of the wind field simulation data could also provide the theoretical guidance to actual flight experiment.

Key words: airborne weather radar, wind field simulation, fluid mechanics, wind-shear
