摘　　要：提出了一种基于连续波(CW)雷达的目标二维运动轨迹的测量方法。在现有径向位移和方位角测量的基础上,通过构建几何模型,进一步推导了横向位移的测量方法和相关运动参数的理论精度,实现了目标二维运动轨迹的测量。对近距离单摆摆动轨迹进行测量,其结果符合运动学规律,径向位移和横向位移测量精度分别为12μm和2.2 mm,验证了所提方法的有效性和精确性。在近距离目标运动参数测量与轨迹分析上有较好的潜在应用价值。An accurate measurement method based on continuous wave（CW） radar for two-dimensional（2 D）motion track of target is proposed.On the basis of existing radial displacement and azimuth measurement,deduces transversal displacement measurement method and theoretic precision of correlative motion parameters by building geometric model,2 D motion track measurement of target is realized.Swing track of close range simple pendulum is measured,and the result accords with kinematics regularity,measurement precision of radial displacement and transverse displacement are 12 μm and 2.2 mm,respectively,verify the effectiveness and accuracy of the method.This method has good potential application value in movement parameters measurement and track analysis of close range target.
