摘　　要：基于冷原子重力仪的动态测量技术区别于应用相对重力仪动态测量重力值方法,具有高精度、无漂移、长期稳定测量等突出优势,然而重力仪从静基座实验走向野外动态测量,仍受体积、死区时间、噪声等多重因素的影响。综述了国内外冷原子重力仪动态测量技术的研究进展。首先论述了冷原子重力仪基本原理,分析了小型化及惯性稳定平台、隔震减震“、死区时间”补偿、组合测量等动态误差抑制技术;然后详述了冷原子重力仪在陆、海、天、空一体化动态测量开展的若干代表性工作;最后展望了冷原子重力仪测量技术新方法及军事等应用领域的前景。The dynamic measurement technique based on cold atom gravimeter is distinguished from the application of relative gravimeter dynamic measurement of gravity value method,which has the outstanding advantages of high accuracy,no drift,long-term stable measurement,etc.However,the gravimeter from the static bench experiment to the dynamic measurement in the field is still affected by multiple factors such as the volume,the dead time,the noise,and so on.This paper summarizes the research progress of the dy⁃namic measurement technology of cold atom gravimeter at home and abroad.First,it discusses the basic principle of cold atom gravimeter,analyzes the miniaturization and inertial stabilization platform,vibration isolation and damping,“dead time”compensation,combined measurement and other dynamic error sup⁃pression techniques.Second,it details some representative work carried out by the cold atom gravimeter in the integration of dynamic measurements in the land,sea,sky and space.Finally,it looks forward to the new methods and the military and other applications of cold atomic gravimeter measurement techniques.
