摘　　要：远距离高精度的距离测量和目标定姿是航天遥感、目标识别、导航控制等领域的关键技术。从理论和实验上研究了利用热光二阶关联在深菲涅耳衍射区进行测距的方法,测距的精度优于0.5 mm,并采用原理证明模拟实验验证了利用该测距方法实现测姿的可行性。此方法可作为传统激光测距技术的补充,并可以实现远距离高精度测距。此方法具有可利用恒星等自然光源实现测距与测姿以及对能量等资源需求较少的优点,为卫星定位等空间测距需求提供了一种新的解决方案。Long-distance and high-precision range and attitude measurements are key technologies in fields such as aerospace remote sensing,target recognition,and navigation control.Here,we theoretically and experimentally study the second-order correlations of the thermal light field for deep Fresnel-zone ranging,and we achieve a precision of 0.5 mm.In addition,we demonstrate with a proof-of-principle simulation experiment that this ranging method can be utilized to measure the target attitude.This method,which can achieve high-precision range measurements over long distances,can be used as a supplement to traditional laser-ranging technology.This method can employ natural light sources such as stars light to measure distance and attitude,and has less demand for energy and other resources.It can provide a new solution for satellite positioning and other space ranging needs.
