论文摘要
在这项工作中，提出了一种使用双轴相关干涉雷达直接在三个维度中直接测量目标速度的方法。最近的进步表明，通过在空间多样化的光圈位置测量的信号来实现目标的角速度的测量。通过利用多个正交基线并使用常规的多普勒速度方法获得径向速度，只能使用三个接收天线和一个单个发射器即可获得完整的三维速度矢量，而无需跟踪。 $ \ text {41.8 GHz} $带有$7.26λ$天线基线的双轴干涉雷达以及对目标移动的测量值与雷达阵列平面平行，以及与径向和切线速度的组件相似的目标移动。这些实验实现了$ \ text {41.01 mm} \ cdot \ cdot \ cdot \ text {s}^{ - 1} $（$ 10.5 \％$）的总速度根平方错误的目标（$ 13.5 \％$）用于目标移动，该目标与径向运动和切向运动相对于阵列的组成部分；每个实验分别实现了估计的轨迹角度RMS $ 10.42^\ CIRC $和$ 5.11^\ CIRC $。
In this work, a method for directly measuring target velocity in three dimensions using a dual axis correlation interferometric radar is presented. Recent advances have shown that the measurement of a target's angular velocity is possible by correlating the signals measured at spatially diverse aperture locations. By utilizing multiple orthogonal baselines and using conventional Doppler velocity methods to obtain radial velocity, a full three-dimensional velocity vector can be obtained using only three receive antennas and a single transmitter, without the need for tracking. A $\text{41.8 GHz}$ dual axis interferometric radar with a $7.26λ$ antenna baseline is presented along with measurements of a target moving parallel to the plane of the radar array, and of a target moving with components of both radial and tangential velocity. These experiments achieved total velocity root-mean-square errors of $\text{41.01 mm}\cdot\text{s}^{-1}$ ($10.5\%$) for a target moving along a plane parallel to the array, and $\text{45.07 mm}\cdot\text{s}^{-1}$ ($13.5\%$) for a target moving with components of radial and tangential motion relative to the array; estimated trajectory angle RMSEs of $10.42^\circ$ and $5.11^\circ$ were achieved for each experiment respectively.
