中文摘要：
利用地基多普勒天气雷达数据,提出机载雷达扫描的模拟仿真算法,并建立了仿真扫描的理论模型。该模型利用数据分层几何投影,处理速度较快、精度较高,可应用于扇形扫描和圆锥扫描。在理想情况下,设计了消除地物回波的算法及多普勒速度退模糊的算法。试验表明,仿真回波可应用于机载气象雷达实际观测前的扫描方式可行性研究,有助于分析机载雷达探测的云雨回波特性。
英文摘要：
Based on ground base radar data,the simulation algorithm of airborne radar is proposed and an ideal model of simulation scanning patterns is also established.The algorithm is quicker and precise with the geometrical projection of divided data levels.The algorithm can be used in both sector scanning and taper scanning.At ideal conditions,this paper also discusses the algorithm of the ground echo eliminating as well as the Doppler velocity dealiasing.The results show that simulated echo could be applied to the feasibility study of scanning types before the real flight observation of airborne Doppler weather radar,and helps analysis its cloud and rain echo characteristics.
