将两方位两要素法的数学模型应用于三方位一速度法计算目标运动要素时的计算量非常大,计算公式也比较繁琐.本文通过对三方位一速度的图解法进行研究,给出了三方位一速度计算目标运动要素的1种算法.该算法能准确地计算出目标的运动要素,且计算量较小,效率更高.%The mathematical model for solving the factors of target motion with two bearings plus two known factors is also used for solving the factors of target motion with three bearings plus known speed, but the amount of calculating is very large. And the formula is fussy. The graphic method of solving the factors of target motion with three bearings plus known speed is studied,and an algorithm is proposed in this paper. Using this algorithm, the factors of target motion can be solved correctly. The amount of calculating is smaller. So the algorithm is more efficient.
