摘要
不同飞行平台的运动特性存在较大差异,对加载SAR的运动补偿要求也有所不同。文中通过建立非理想运动模型,定量分析了某型运输机、某型无人机和某型无人飞艇的飞行航迹数据,估计了不同飞行平台的运动参数,得出某型运输机相对适于作为SAR平台,飞艇SAR运动补偿难度最大。无人机由于性能差异大,运动补偿要求需要具体情况具体分析。
The motion characteristic of different aerocraft is different, so SAR motion compensation requirement based on different aerocraft is different. This paper builds an aerocraft nonideal moiotn model, quantificationally analysed flight path data, estimates different aerocraft＇s motion parameter. It is gained that the aerotransport best suits the SAR platform, the airship SAR＇s motion compensation is the most difficult, unmanned aircraft＇s motion characteristic has lots of differences, which motion compensation re- quirements should be particularly analysed.
