有源雷达定标器用于从复图像数据中提取多通道极化合成孔径雷达（SAR）的幅相特性。本文介绍了在加州戈德斯通的一个校准场地上使用NASA/JPL DC-8飞机SAR进行的实验结果。作为实验的一部分，部署了具有可调极化特征的极化主动雷达校准器（PARC）。实验结果表明，该方法可以成功地用于极化SAR图像的校正。PARC校准程序的应用限制进行了讨论。<>
Active radar calibrators are used to derive both the amplitude and phase characteristics of a multichannel polarimetric synthetic aperture radar (SAR) from the complex image data. Results are presented from an experiment carried out using the NASA/JPL DC-8 aircraft SAR over a calibration site at Goldstone, California. As part of the experiment, polarimetric active radar calibrators (PARCs) with adjustable polarization signatures were deployed. Experimental results demonstrate that the PARCs can be used to calibrate polarimetric SAR images successfully. Restrictions on the application of the PARC calibration procedure are discussed.<>
