摘要
航空遥感观测试验用于保证探测数据与产品的真实有效,对于星载遥感技术的发展起着至关重要作用。为验证陆地水资源卫星主载荷主被动一体化微波探测仪在轨工作,研制了微波主被动一体化探测仪器,开展机载校飞试验,验证卫星载荷的设计及探测数据精度。为保证真实性检验的充分性,考虑载机空间的局限,机载L波段主被动复合探测器的设计指标与星载仪器尽可能一致。针对回波时间短带来垂直下方强干扰的问题,机载样机采取硬件机械扫描、软件时序校正的措施。经集成测试,结果表明机载L波段主被动复合探测器满足设计要求,可用于验证星载仪器工作,探测数据可用于反演应用。
Aerial remote sensing observation test is used to ensure the truth and effectiveness of detection data and products,which plays a vital role in the development of space borne remote sensing technology.Aiming the technical index of the main load of the land water resource satellite,the inversion precision of data are verified by airborne flight calibration test.In order to ensure the adequacy of authenticity inspection,the design index of the airborne detector is as possible with the space borne instrument under the limitation of the space layout of the onboard aircraft,and the resolution determined by different platform is also designed in the same proportion.The integrated test results show that the airborne detector meets the design requirement,which can be used to verify the space borne instrument,and the data can be used to verify the accuracy of the inversion algorithm.
