摘要
针对小样本情形下用传统方法估计精度难以得到满意结果的情况,提出了用递推Bayes估计法来估计落点精度和密集度的方法,将先验信息和后验信息相对化.给出了递推Bayes估计的递推表达式.最后经仿真比较,证明了此种方法相对于矩估计法有更高的精度.
Because of the difficulty of getting reliable data by classical method, a method to estimate landing precision and concentration by Bayesian method of dynamic recurrence was introduced, in consideration of the relativity of prior and posterior information. The expression of recurrence estimate was developed. At last, the result of simulation showed that this method had higher degree of accuracy than moment estimator method.
