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。

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.
