在二维平面上,对于匀速直线运动目标,如假定静止单站能够在目标移动路径上等间距的连续三次获取目标的方位信息,则即能由目标的移动轨迹线方程和测站与目标间的方位线方程,导出目标航向角的解析表示式。模拟计算验证了公式的正确性,而误差分析则再次证实,仅基于纯方位测量所获得的解的精度是较低的。 In a two-dimensional plane, for a stationary linear target, assuming that the stationary single station can obtain the target’s azimuth information three times in a row at equal intervals on the target moving path, the moving trajectory equation of the target and the target- Of the azimuth line equation, derived target heading angle analytic expression. Simulation calculations verify the correctness of the equations, while error analysis again confirms that the accuracy of the solution obtained on purely azimuth measurements is lower.
