固定单站对移动目标航向角的一种测算方法

假设移动目标匀速直线运动,利用径向距离的程差与目标飞行距离之间的近似关系,由时差方程即能证明被测目标相邻飞行距离之比是与观测站相邻时差之比相等的.利用这一附加关系,就能在时差与方位测量的基础上,直接由几何关系解出在相邻飞行距离不等情况下的目标航向角.从工程实际出发,所给出的结果为完整解决相邻目标飞行距离不等时的固定单站...

A measuring method of course angle for mobile target with fixed station

Provided that the target is uniform motion alone straight line and making use of the approximation relation between path length difference of radial distance and air-distance of target,a identical relation,that the specific value of adjacent air-distance of target is equivalent to the one of adjacent time difference of observation station,can be certified from the time difference equation.By use of this auxiliary relationship,the course angle of target when the adjacent air-distance is unequal can be solved from geometric relationship based on the measurement of time difference and direction.From the viewpoint of the engineering design,the result can supply the efficacious technical support for solving the passive location problem of fix single station when the adjacent air-distance is unequal.
