A double-angle polarizing atmospheric corrector(DPAC) on an airborne platform is established for the quantification of remote sensing data.This sensor acquires spectral,angle and polarization information in image areas by time synchronization and space covering to implement the high-precision retrieval of aerosols and water vapors.Then,by taking these atmospheric parameters obtained by atmospheric retrieval as an input,the high-precision atmospheric correction for optical remote sensing images is achieved with a radiation transfer model.The DPAC has two detecting directions,one is along the nadir angle(0°) and the other is a forward angle(55°).It covers 8 wavebands ranging from 0.49 μm to 2.25 μm,among which five wavebands are designed for polarizing measurement.To overcome the polarization measurement errors caused by detection target inconsistent,the higher precision and integrated structure is designed to ensure the field overlap accuracy of polarization detection channels.The results of lab calibration and test show that the viewing field coincidence is better than 95% and the polarization accuracy is better than 1%(DoLP=03),which meets the requirements of the DPAC for specifications.
