Design and optical characteristics test of airborne remote sensing calibration targets
航空遥感载荷验证靶标设计与光学特性测量

To build a comprehensive calibration f ield for airborne sensors, a set of artif icial targets were designed during 2008 and 2009. The targets include resolution bar target, siemens star target, refl ectance target, MTF(modulation transfer function) target, and spectral characteristic target for spatial-resolution evaluation, radiometric and spectral calibration of optical sensors. The targets can be washed, spliced, and reused, corresponding to high resolution and high fl exibility of airborne remote sensing. To test optical characteristics of the targets, in-situ spectral measurement and bidirectional refl ectance factor (BRF) measurement were conducted on refl ectance target, MTF target and spectral characteristic target. The results show that, the targets have good spectral, lambertian and contrast characteristics, which can be used in airborne sensor calibration experiments and related applications. In this paper, the design and optical characteristics test of the targets are introduced in detail, which set an example for the design of aerospace and airborne remote sensing calibration f ield in future.
