摘 要: | 在线捕获GEO远距离暗弱目标,实时监视轨道目标状态对于空间安全具有越来越重要的意义。在灵敏度接近14 Mv情况下,密集恒星、恒星散射光效应将极大影响目标探测。为解决上述问题,提出一种背景稠密恒星同步剔除和空间目标证认方法,利用目标短时间内规律运行的特征,实现目标的捕获、分类和在线跟踪,地面仿真和试验充分验证了方法的有效性和准确性。文中方法对于太阳系内行星、小行星探测等深空项目亦具有重要的借鉴意义。

Abstract: | In orbit capturing and real-time monitoring the status of distant dimmer space targets is of vital importance for space safety. However, when the sensitivity approaches 14 magnitude, the intensive stellar population, the stellar scattering light will reduce the detection efficiency greatly, resulting in a limited detection range and ability. To solve this problem, a simple method for space object capturing, classification and online tracking was presented, synchronously eliminating the dense background stars and sequentially extracting the possible space targets, utilizing the regular motion of a moving object in a short timespan. Ground simulations and tests validate the effectiveness and accuracy of the method. It seems that this method can also be used as a basic function for deep space projects, such as asteroid and planet exploration in the solar system. |
