摘要
通过研究多基地雷达定位的马尔可夫算法,提出了一种适用于大数据量情形的简化目标定位方法,解决了因算法简化而衍生的测量误差协方差矩阵非正定问题。通过实例仿真,对定位结果的"定位精度的几何稀释"曲线进行分析,证明了本算法能够保证定位结果有效,并提高了运算效率。
Through studying on Markov estimation algorithm for multistatic radar positioning, a simplified positioning algorithm is proposed to solve the problem that error covariance matrix is non-positive definite. Simulation and analysis of the GDOP（Geometrical Dilution of Position） curve prove that this positioning algorithm is effective, and the computation efficiency is remarkably improved.
