航向误差对解算目标运动要素误差的影响

摘要

To solve the problem that UUV needs to calculate the target motion element when carrying out underwater operations ,this paper analyses the influence of the course error on the calculation of target motion element and establishes a second‐order error model .The model is used for analyzing the influence of the course error on calculating target motion element error .It is proved that the method can take into account not only the navigation error but also the none‐liner problem in calculating target motion elements and also that the method is practicable and useful in providing course information .%针对UUV在水下探测时需要对水下移动目标的运动要素进行测定的问题，通过对四方位测定目标运动要素方法进行分析建立了其二阶误差分析模型，并在该模型基础上分析航向误差对解算目标运动要素误差的影响。结果证明：该分析模型可实现对航向误差影响的有效分析。
