首先本文介绍了天文导航的基本原理，然后提出利用短波红外技术检测星体图像， 在对星体图像进行小波变换的基础上，利用多尺度分析方法，确定图像自适应阈值，实现图像小波域的去噪，达到星体目标检测的目的，该方法能够更好地提高星体检测精度，从而提高系统设备的导航精度。通过试验验证表明，该系统检测精度满足试验测量要求。

Research and Application of Astronomical Detection System Based on Shortwave Infrared

Firstly, the paper introduced the principle of celestial navigation, and then put forward to detecting star images by using the shortwave infrared. Based on wavelet transform, a new algorithm of infrared small target detection is presented. The multiple scale wavelet analysis is employed, and adaptive threshold is determined to realize image de-noising in wavelet realm. The method has higher star detection accuracy, So as to improve the navigation precision of the system. The practices show that the measure request is contented.
