摘要

本文研究了利用三波束多普勒激光雷达估计车辆速度时的精度稀释问题。这种系统已被提议作为机载重力测量系统中差分GNSS速度解决方案的补充或替代。通过解析推导出激光雷达波束的最佳方向，并通过数值模拟得到波束姿态，使估计垂直速度的误差协方差最小。

Dilution of Precision in the Problem of Estimating the Aircraft Velocity by Means of Three-Beam Lidar Measurements

The paper presents our study on the dilution of precision in the problem of estimating the vehicle’s velocity using a three-beam Doppler lidar. Such a system has been proposed as an addition or replacement to the differential GNSS velocity solution in an airborne gravimetry system. We analytically derive optimal directions of lidar beams and use numerical simulation to obtain their attitude which minimizes the error covariance of estimated vertical velocity.
