- Filter estimate, error covariance and probability of data association relative to the algorithm were deduced, and new gating techniques for target tracking in clutters were given. 推导了该算法中相关的滤波估计、滤波误差协方差和数据关联概率，并且提出了跟踪门的确定方法。
- The upper bound of minimum error covariance satisfying all the uncertainties is found and the optimal problem is solved in the framework of linear matrix inequality (LMI). 首先，根据噪声方差不确定模型，找到满足所有不确定性的最小方差上界，在线性矩阵不等式(LMI)框架下求解优化问题，得到近似到达代价的表达形式；
- Because of the computer word length, filter algorithm is prone to accelerate error.The error covariance will be out of symmetry, as a result, instability will appear in the value calculation. 摘要由于计算机有效字长的限制，滤波算法在计算机上实施时易于产生误差积累，误差协方差失去正定性或对称性，从而出现数值计算中的不稳定现象。
