This paper introduces the development study of Reflector board ( cooperative target) reflectivity measuring instrument.

本文介绍了反光板（合作目标）反射率测量仪的研制。

Usually, conventional incoherent weather radar is used to provide only the information on the position of a weather target and its radar reflectivity by detecting echo intensity.

通常非相干的常规天气雷达的应用仅仅是通过雷达回波强度的探测来提供天气目标物的位置和其反射率的信息。

The visibility measurement error caused by non-blackbody target is analyzed. It is shown that the relative measurement error increases along with the increase of the visibility and the target's reflectivity. To ensure the measurement precision, the target with reflectivity low enough is required.

作者对非黑体目标引起的测量误差进行了分析，结果表明相对误差随着目标物反射率的增加和能见度的升高而增大，为了保证测量精度，需要采用反射率足够低的目标物。

It is always the emphasis to improve the resolution for reconstructing target reflectivity in research of inverse synthetic aperture radar ( ISAR) imaging.

提高图像分辨率一直是ISAR研究的重要内容，常规的ISAR成像算法在这方面存在着不足。

Some different thickness aluminum reflective films were produced on silicon substrate by using the electron-beam evaporation method and high purity aluminum target. The reflectivity curves of Al film in the visible light region were measured, the density and conductivity of films were analyzed.

采用电子束蒸发的方法，以高纯度的Al为靶材，硅片为衬底，制备了不同厚度的Al反射膜，并测量了在可见光范围内反射率曲线，分析了薄膜的致密性和电导率。
