To build a comprehensive calibration field for airborne sensors

a set of artificial targets were designed during 2008 and 2009.The targets include resolution bar target

siemens star target

reflectance 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 flexibility of airborne remote sensing.To test optical characteristics of the targets

in-situ spectral measurement and bidirectional reflectance factor（BRF） measurement were conducted on reflectance 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 field in future.
