摘要
空间目标探测与识别技术是空间资源开发、空间安全等方向应用的前提条件,同其他方式相比,激光探测具有其突出的优势。当前传统的空间监视网是以微波雷达和光学望远镜为基础,激光探测与之相比具有系统简单、效费比高、能探测空间目标多种特征参数的优点。介绍了激光探测空间目标中的空间目标轨道确定、几何形状估计、对装配的光学设备检测和对空间目标的振动识别等几种目标识别技术。最后分析了激光探测在空间目标识别中存在的问题和发展的方向。
Space targets detection and identification is a key technology in space applications such as space security,attack-warning,debris detection ect.Among various detection tools,laser technology has its special advantages under certain condition.Cempaved with the conventional space surveillance network which is composed of radar and optical telescope,laser system can get mone information about the torget meanwhile boasts mone compact size,higher efficiency.The paper introduces how to use laser to determine the orbit of the space target,how to estimate the target′s shape through the return signal,and how to measure the vibration spectrum of the target.Also introduced is the development and future of the space target detection and identification by laser.
