摘要
利用目标三线坐标的面积约束关系和海伦 秦九韶公式判定定位区域 ,在三线坐标校正的基础上 ,提出了一种新的测距定位算法 .在没有其他有用信息的情况下 ,三线坐标校正相当于在定位直线中引入了面积约束 .仿真实验的结果表明 ,该算法具有较强抑制非直达波误差的能力 .
A new source location method is proposed based on the relation between the trilinear coordinates of the source and the area of basic triangle.Heron-Qinjiushao formula is used to calculate the area of triangles.The location region of the source is determined and the trilinear coordinates of the source are corrected by using the constraint on area of triangles.Simulation studies show that the presented method outperforms the traditional method by reducing the standard deviation for scenarios with large non-line-of-sight errors.
