摘　　要：针对不同传感器的测量值时间不匹配、定位精度低等问题,提出一种改进型三角定位法。引入琢-茁-酌滤波器,一方面对测量值滤波能够减小输入值误差;另一方面利用滤波得到的角速度和角加速度进行外推,将测量值进行时间配准,旨在提高定位精度。同时,分析了影响定位精度的几个因素,并进行了仿真验证。结果表明改进型三角定位法极大地提高了精度,并在传感器的布阵上给出依据,这对作战指挥决策具有重要的意义。For the questions that the time of measurement of different sensors is not matched,and the positioning accuracy is low,an improved triangulation method is proposed. Introducing α-β-γ filter,on the one hand,filtering the measurement value can reduce the input error;On the other hand,getting the angular velocity and angular acceleration obtained by filtering to extrapolate,the aim is to improve the positioning accuracy. At the same time,this paper analyses several factors that affect the positioning accuracy,and accomplishes the emulation proofing. The result shows that the improved triangulation method greatly improves the precision,and it gives the basis for the position of sensors, this is very important for the operational command decision.
