摘要
基于两部组网雷达与空域目标构成的空间几何三角关系,综合利用组网雷达对目标的测量信息,使用正弦定理、余弦定理解算空域目标位置,提出了两种雷达组网三角融合定位算法融合解算空域目标位置;并使用全微分方法分析组网三角定位算法误差构成,利用期望分析方法完成了组网三角定位算法误差一阶矩和二阶矩解算。仿真结果表明:组网三角定位精度明显优于单部雷达。
Based on space triangle relation reformed between airspace target and two networked radars,using measurement information and law of sines & cosine to resolve the position of airspace target,the algorithm of radar networking triangle fusion location (ARNTFL) is proposed in the paper.Error composing is analysed by using the method of differential and first-order and second-order moment of ARNTFL is completed by using expectation analysis.Simulations demostrated that location precision of ARNTFL is obvious better than single radar.
